The 'unlucky submarine' Choi Won-jun (Doosan Bears) has failed again to achieve his first win. He has gone winless in 8 consecutive games since the opening.

Choi Won-jun started the fifth game of the season against the LG Twins in the 2025 Shinhan SOL Bank KBO League at Jamsil Stadium in Seoul on the 6th, pitching 5 innings with 6 hits allowed (2 home runs), 1 walk, 3 strikeouts, and 5 earned runs, putting himself in a losing position.

In the top of the first, Choi Won-jun allowed a sacrifice fly to Austin Dean, and in the top of the second, he gave up a solo home run to Park Dong-won, heading into the top of the sixth trailing 1-2.

He was unstable from the start. He allowed consecutive hits to lead-off batters Hong Chang-ki and Park Hae-min, putting himself in a crisis with runners on first and second base, and surrendered a three-run homer to Austin. The fifth pitch thrown in a favorable count of 1B-2S was a curveball (122 km/h) that was high, resulting in a 130m left-center field home run.

Choi Won-jun faced the next batter, Moon Bo-kyung, and allowed a single to left before being replaced by Lee Young-ha. Lee Young-ha managed to overcome a crisis with 1 out and runners on first and third base after Park Dong-won's sacrifice bunt and Kim Hyun-soo's infield single, striking out Oh Ji-hwan on a swinging strikeout and stopping Moon Seong-joo with a line drive to second base, but he could not erase Choi Won-jun's losing plight.

Before the game, Choi Won-jun had recorded 3 losses without a win in 7 games with an earned run average of 3.93. He was challenged for his first win again after 7 games and 8 tries, but victory eluded him once more that day.
