Flexen's Return Powers Jamsil
Doosan Bears are picked to win at home against KIA Tigers, supported by Chris Flexen's back-to-back preseason dominance, the team's 5-1 preseason record, and Jamsil home advantage in the stadium's historic final season. KIA's ace James Naile presents the principal threat — his 2025 ERA of 2.25 gives him the tools to shut down any lineup — but KIA's 2-1-4 preseason form and ongoing infield reconfiguration (Kim Do-young at SS, new additions Castro and Dale) suggest they have not yet reached optimal form. At an estimated 1.90 odds, the model probability of 56% exceeds the implied probability of 52.6%, yielding a modest positive edge of 3.4 points. This is a small-stake preseason play only.
On March 22, 2026, the Doosan Bears and KIA Tigers meet at Jamsil Baseball Stadium for the second game of a back-to-back preseason series. Jamsil opened on March 21 for the first time this spring, making this one of the final tuneups before the KBO regular season opener on March 28.
Doosan enters with renewed optimism under first-year manager Kim Won-hyung, anchored by the return of Chris Flexen — six years after his dominant 2020 KBO stint — alongside re-signed ace Zach Logue. The addition of infielder Park Chan-ho via free agency further strengthens the club. KIA, the 2024 KBO champions who regressed in 2025, are attempting a bounce-back season built around the surprise re-signing of ace James Naile, the re-signing of veteran Yang Hyun-jong, and the ambitious shortstop transition project for star third baseman Kim Do-young.
Both teams have been active in the preseason. Doosan sits near the top of preseason standings at 5-1 (as of March 17), while KIA has been inconsistent at 2-1-4, still working through their 4th and 5th starter competitions. The stakes for this game are low in terms of standings, but high in terms of final lineup and rotation fine-tuning before opening day.
News & Trends
Flexen struck out 8 batters in 3.1 innings against Kiwoom on March 12 and followed with 8 Ks in 4 innings against Hanwha on March 17. His return to Doosan's rotation appears seamless and gives the Bears a genuine ace entering the season.
Logue went 10-8 with a 2.81 ERA in 2025 and posted an outstanding 2.14 ERA in the second half, tops among lefty starters in that stretch. Doosan retained him at $1.1 million total, forming a formidable 1-2 rotation punch with Flexen.
The former KIA shortstop joined Doosan via free agency, filling a critical infield need. Park is a quality defender and on-base threat projected to bat second in the Doosan lineup, immediately upgrading their offensive table-setting.
Son of MLB legend Mike Cameron, Daz posted .282/.361/.593 with 18 homers in Triple-A in 2025 (OPS .954). Doosan expects him to provide power and excellent outfield defense in the foreign hitter role.
As of March 17, Doosan leads the preseason at 5-1, demonstrating balanced performance across pitching and offense. The team's atmosphere under new manager Kim Won-hyung has been described as positive by media covering the camp.
Jamsil Baseball Stadium, open since 1982, will be demolished after the 2026 season to make way for a new 35,000-seat domed stadium by 2031. This creates a powerful emotional incentive for Doosan players and fans alike throughout the season.
Reliever-turned-starter Lee Young-ha, who re-signed for 5.2 billion KRW in FA, is working back into the rotation. Manager Kim guided Lee as a rotation pitcher during his coaching days, making the transition natural for the club's 4th starter slot.
Naile went 8-4 with a 2.25 ERA in 27 starts in 2025, logging 164.1 innings and 152 strikeouts. He was expected to pursue MLB opportunities but surprisingly chose to stay in Gwangju. His retention is the single most important KIA offseason development.
Oller is rated as having superior raw stuff compared to Naile but has a history of inconsistency and injury. Re-signed for $1.2 million, he forms the back end of a formidable top-2 foreign pitcher combo for KIA.
The only KBO pitcher to ever throw 150+ innings for 11 consecutive seasons, Yang has been KIA's top Korean starter for over a decade. His 2025 season showed the effects of aging, but his leadership and durability remain valuable.
KIA's primary shortstop Park Chan-ho signed with Doosan in free agency, creating a significant hole. KIA's response involves transitioning Kim Do-young to short and adding Australian infielder Jarryd Dale on the Asian quota slot.
Manager Lee Bum-ho officially launched the conversion of star third baseman Kim Do-young to shortstop. Kim played the position in high school and briefly in his pro debut but has been at third since. Defensive errors early in the season are a real possibility.
KIA sits near the bottom of preseason standings at 2-1-4 as of March 17. The 4th and 5th starter competitions remain unresolved, and the new infield alignment has yet to stabilize. Opening the season on the road at SSG adds pressure.
KIA is the only KBO franchise entering 2026 with two foreign hitters and zero foreign pitchers (Asian quota Dale is a position player). This is an unconventional roster construction that adds offensive depth but creates uncertainty in the back of the rotation.
The 2026 Shinhan SOL Bank KBO League is the league's 45th season. LG Twins are defending champions. Teams are finalizing lineups and rotations this week, making these final preseason games critically important.
Starting in 2026, each KBO team may carry one additional player from an Asian or Australian league alongside the usual three foreigners. This has expanded roster options for all clubs, including both Doosan and KIA.
KBO shortened the pitch clock by 2 seconds for 2026. This puts more pressure on pitchers to work quickly and may slightly benefit agressive hitters who thrive against less deliberate deliveries.
Doosan conducted their entire spring camp at Blacktown International Sports Park in Sydney from January 19 to February 19, using match-based preparation to build competitive readiness. Players have credited the trip with building team chemistry.
Three candidates are competing for the final two rotation spots: Lee Ui-ri (returning from surgery), Kim Do-hyun (second full year), and Hwang Dong-ha (former 5th starter). Resolution of this competition is critical for KIA's early-season stability.
New Doosan manager Kim Won-hyung, a former pitching coach, has stated he will maintain a pool of 6-7 rotation candidates rather than locking into exactly five starters. This approach reduces injury risk and keeps competition high throughout camp.
Australia's Jarryd Dale, signed for $150,000 on the Asian quota slot, is a versatile infielder who reached Triple-A with the Padres. He will handle shortstop duties while Kim Do-young transitions, providing temporary stability in the infield.
The biggest positive news for Doosan is the seamless return of Chris Flexen. His back-to-back dominant preseason starts have dispelled any concerns about rust after six years away from KBO. Combined with Logue's proven form from 2025, Doosan enters the season with arguably one of the most reliable foreign 1-2 rotation combos in the league. Park Chan-ho's arrival from KIA also directly strengthens one of Doosan's historically weaker positions.
For KIA, the best news is Naile's decision to stay. His 2.25 ERA in 2025 was among the best in the entire KBO for foreign pitchers, and his retention gives KIA an ace capable of winning any individual game. However, the departure of Park Chan-ho, the uncertainty surrounding Kim Do-young's shortstop experiment, and the unresolved 4-5 starter situation introduce instability. KIA's preseason 2-1-4 record signals the team has not yet found its optimal configuration, which could translate to a slow start to the regular season.
Key Players
Returning to Doosan after six years, Flexen posted dominant preseason numbers: 8 Ks in 3.1 IP vs Kiwoom (March 12) and 8 Ks in 4 IP vs Hanwha (March 17). His 2020 KBO season featured an ERA of 3.01, postseason heroics, and a Korean Series appearance. He arrives in top form.
Logue went 10-8 with a 2.81 ERA in 2025, including a 2.14 ERA in the second half (No. 1 among lefties in that stretch). His proven performance gave Doosan confidence to re-sign him at $1.1M, providing the stable second starter they needed.
The former KIA shortstop brings polished defense and plate discipline to Doosan's lineup. Doosan's infield was a weakness in recent seasons; Park's arrival directly addresses that. He is expected to bat second and serve as a catalyst for the Bears' offense.
Doosan's Korean ace holds down the third spot in the rotation. His curveball-changeup combination is among the best in the league and he has shown ability to deliver in high-pressure games. A reliable arm bridging the gap between the foreign 1-2 starters and the back-end competition.
Naile was arguably the best foreign pitcher in the KBO in 2025 with an ERA of 2.25 across 27 starts, 164.1 innings, and 152 strikeouts. His surprise re-signing for $2M makes KIA's rotation the envy of the league at the top. He can absolutely dominate a Doosan lineup.
Analysts consider Oller's raw stuff superior to Naile's, but he has been held back by inconsistency and injury history. Re-signed for $1.2M total, he can be a dominant No. 2 when healthy and on form. His health and consistency will determine how formidable KIA's rotation truly is.
A KIA legend with 186 career wins and three Korean Series titles, Yang remains the primary Korean ace despite aging curve signs in 2025. His KBO-record 11 consecutive 150-inning seasons speak to his durability, and he re-signed for 2+1 years at 4.5 billion KRW to continue anchoring the KIA rotation.
One of the KBO's elite offensive players, Kim Do-young is KIA's most impactful bat. His ongoing shortstop transition adds a layer of uncertainty to his 2026 value — if the defensive experiment fails early, it could disrupt the team's rhythm. On offense, he is capable of carrying the KIA lineup.
The marquee pitching matchup hinges on whether Naile (KIA) or Flexen (Doosan) draw the start. Both are elite by KBO standards: Naile with his 2.25 ERA from 2025, Flexen with his dominant preseason returns. At the plate, Doosan's lineup has been upgraded by Park Chan-ho's arrival, while KIA's lineup power rests heavily on Kim Do-young, who is still finding his footing at shortstop. This preseason game will likely see controlled innings from both aces, meaning bullpen performance and bench depth may ultimately decide the outcome.
In a direct pitching comparison, KIA holds a slight edge at the very top with Naile's 2025 ERA of 2.25 representing the gold standard for foreign pitchers in the league. However, Doosan's combination of Flexen and Logue creates more depth and reliability from the 1-2 spots. If this is a preseason tuneup where aces pitch limited innings, the bullpen and bench talent become equally important, and both clubs have invested significantly in those areas.
Offensively, Doosan's addition of Park Chan-ho and Daz Cameron represents a meaningful upgrade. KIA still has Kim Do-young as their offensive centerpiece, but losing Park Chan-ho from the middle of their lineup and infield creates a gap that new signings Harold Castro and Jarryd Dale will need to fill. The positional switch for Kim Do-young, while strategically sound long-term, introduces defensive variance in the near term. These factors collectively suggest Doosan has the more stable team configuration heading into opening day.
Strength Comparison
KIA holds a narrow edge in pure pitching quality, driven by Naile's elite ERA and Yang's veteran experience. However, Doosan's 1-2 rotation (Flexen/Logue) provides comparable reliability and depth. Offensively, Doosan's roster upgrades (Park Chan-ho, Daz Cameron) have narrowed or erased KIA's previous advantage. On defense, KIA is in flux due to Kim Do-young's position transition, slightly tilting that category toward Doosan. Momentum strongly favors Doosan: their 5-1 preseason record, the energy of a new manager, and the historic significance of Jamsil's final season all contribute to a positive environment. KIA's 2-1-4 preseason record and unresolved roster questions register as below-average momentum.
When weighing the full team picture, Doosan enters this preseason finale in a stronger overall position than KIA despite having a slightly weaker ace at the very top. The key differentiator is organizational stability. Doosan has resolved its top-line roster questions, the new manager's vision is clear, and the team's culture is energized by both the Flexen reunion and the farewell-season narrative at Jamsil.
KIA's ceiling remains higher on paper — a healthy Naile, Oller, and Yang rotation powering a Kim Do-young-led offense is a genuine contender. But as of this March 22 preseason game, too many variables are still in flux for KIA. Their 4th and 5th rotation spots are undecided, Kim Do-young is adapting to a new position, and the new batting order configurations with Castro and Dale are untested. These uncertainties, combined with Doosan's home advantage and superior preseason form, tip the balance in Doosan's favor for this specific game.
Key Factors
Jamsil is Doosan's turf and the team traditionally performs well there. With this being the stadium's final season, players have extra motivation. The crowd energy in late-preseason home games at Jamsil is historically strong.
Doosan's 5-1 preseason record through March 17 is the strongest in the league. Flexen's consecutive dominant starts and balanced team performance signal that the Bears are the best-prepared club entering the regular season.
Naile's 2025 ERA of 2.25 across 27 starts remains the most dominant single-pitcher metric in recent KBO history for foreign players. If he starts this game, KIA has the tools to shut Doosan down completely.
The departure of Park Chan-ho and Kim Do-young's mid-season shortstop experiment introduce meaningful defensive variance for KIA. Early-game errors or miscommunications in the infield can quickly lead to unearned runs in KBO-level competition.
Manager Kim Won-hyung's pitching coach background gives Doosan an analytical edge in managing the rotation and bullpen. His flexible 6-7 starter pool approach keeps the pitching staff sharp and reduces injury risk during the transition to the regular season.
This is a preseason contest. Both managers will prioritize development objectives over winning, meaning lineup configurations, pitch counts, and substitution timing will all differ from a regular-season game. Outcome predictability is inherently limited.
Synthesizing all key factors, Doosan's home field advantage, superior preseason momentum, and resolved roster configuration give them a moderate edge over KIA in this final preseason matchup. Flexen's return has been the story of Doosan's spring: two dominant outings signaling that the 2020 version of himself is back, which gives Doosan a legitimate ace capable of matching Naile's ceiling.
The risks are notable, however. KIA can win this game comfortably if Naile pitches a full, dominant game and Kim Do-young finds his offensive groove. The preseason format amplifies variance — a single bad bullpen inning or an infield error can swing a low-scoring contest. Given these considerations, Doosan is the slight favorite at home, but this is a game where a margin of probability rather than certainty defines the prediction.

Risk Assessment
HighPreseason games carry high inherent unpredictability. Managers may use alternative lineups, restrict pitch counts, and rotate through multiple pitchers regardless of game state. Standard win probability models are less reliable in this format.
Neither team has publicly confirmed their starter for March 22. If a second-tier arm starts instead of the ace-level starters, the entire pitching matchup analysis changes significantly.
Kim Do-young's shortstop transition and Jarryd Dale's KBO debut introduce defensive risk for KIA. Multiple errors in a single game can create unearned run scenarios that distort the true competitive outcome.

Final Verdict: Doosan Bears are the recommended pick in this preseason contest against KIA Tigers. The three primary supporting arguments are: Flexen's back-to-back preseason dominance (16+ combined strikeouts), Doosan's league-leading 5-1 preseason record, and the home-field advantage at Jamsil combined with the unique motivational factor of the stadium's final season. KIA's counter-argument rests almost entirely on Naile's ace-level potential, but the team's 2-1-4 preseason record and ongoing infield transition suggest they are not yet operating at peak efficiency.
At an estimated odds of 1.90, a Doosan win carries a calculated edge of approximately 3.4 percentage points over the implied probability, representing modest but positive expected value. This remains a preseason game with elevated uncertainty — position this as a small-unit speculation rather than a high-conviction wager.
