A Career Born from Draft Day Gasps
Yusuke Oyama was drafted first overall by the Hanshin Tigers in 2016 from Hakuoh University, a surprise pick that drew audible gasps from the draft venue. Originally planned as a second pick, manager Tomoaki Kanemoto changed the plan on draft day. The crowd's reaction at the draft fueled Oyama's determination. In his rookie 2017 season, he became the team's 101st cleanup hitter in September, the first rookie in the four-spot since 1964.
Cleanup Maturation and the 2023 Championship
Oyama's breakout came in 2020 with .288/28 HR/85 RBI, the second-most home runs in the league despite Koshien's pitcher-friendly dimensions. In 2023 under manager Akifu Okada, he started all 143 games as the cleanup first baseman, the first Tiger to do so since Kanemoto in 2009. He won the OBP title with 99 walks and delivered a bases-loaded walk-off hit in Japan Series Game 4 as Hanshin won their first championship in 38 years.
2024 Struggles and the FA Decision
The 2024 season brought adversity: a demotion to the minors in June for the first time in six years, followed by a move to the fifth spot in the batting order from July. He finished with .259/14 HR/68 RBI in 130 games. After the season, Oyama declared free agency. Despite the Yomiuri offering over 2.4 billion yen over six years, he chose to stay with Hanshin for 1.7 billion over five, saying 'I can't forget that earth-shaking emotion. I want to win it all one more time.'

2025 Pennant and the Tigers' Cleanup Lineage
In 2025, Oyama hit .264 with 13 home runs and 75 RBI across 141 games, reaching career milestones of 1,000 hits and 150 home runs while earning his second Best Nine and Golden Glove awards. His nine-year career totals of .268/150 HR/626 RBI place him firmly in the Tigers' cleanup lineage of Fujimura, Tabuchi, Kakefu, Bass, and Kanemoto. From draft-day gasps to an FA commitment worth billions less than the alternative, Oyama's story is one of loyalty rewarded.
Koshien's Wind and Opposite-Field Hitting
Koshien Stadium features a distinctive breeze blowing from right field to left field, commonly called the hamakaze, which is known to suppress home runs by right-handed batters. Oyama, a right-handed hitter calling Koshien home, refined his opposite-field hitting technique to counter this disadvantage. Balls driven to right field catch the tailwind and travel farther. Though not typically classified as a pull hitter, Oyama has maintained a higher-than-league-average ratio of home runs to the right-field side. This technical adaptation effectively reverses the usual disadvantage a right-handed batter faces at Koshien and has been cited as a key factor behind his consistent home run production at the home ballpark.
Defensive Position Changes and Evaluation as First Baseman
Oyama was initially deployed at third base after joining the Tigers. He secured the starting role at third under manager Kanemoto, but from 2020 onward transitioned to first base. At third, his strong throwing arm was an asset, while first base demands wide range and flexible handling of short hops. After the conversion, Oyama earned praise for his reliable receiving of throws from fellow infielders and won the Golden Glove Award at first base in 2023, a rare achievement for a homegrown Tigers first baseman. The positional switch also allowed him to concentrate more on hitting, and is considered to have contributed to his increased home run production from 2020 onward. His case exemplifies how reducing defensive burden can translate into improved offensive output.
Walk Rate as a Measure of Plate Discipline
One defining trait of Oyama's hitting is his ability to draw walks. In 2023 he recorded 99 bases on balls, the most in the league, and won the highest on-base percentage title. This batting eye was not acquired overnight but improved steadily throughout his professional career. A high walk rate forces opposing pitchers to throw more pitches, hastening bullpen fatigue and increasing scoring opportunities for the entire team. Moreover, walk rate serves as an indicator of swing decision quality, reflecting superior recognition of the strike zone. By combining power hitting with this level of plate discipline, Oyama has maintained his reliability as a middle-of-the-order hitter.
