Jung Sung-gon wore the KT Wiz uniform with the 14th overall pick in the 2nd round of the 2015 KBO Rookie Draft. He played an active part at KT until the 2019 season, and after completing military service at Sangmu, he moved to SSG through a trade for the 2022 season.
Jung Sung-gon played in just two games last season, recording an average ERA of 10.13 with 2⅔ innings, 3 runs (3 ERA), 1 hit (1 home run), 4 walks and 3 strikeouts. He averaged only 135 km/h on his four-seam fastball. He was different from the way he threw the ball in the mid-140s during KT.
This season, Jung Sung-gon changed the pitching mechanism using sports science in the Future Team. He was against changing the pitching mechanism, but he came to think positively after seeing the change.
Jung Sung-gon’s problem, as seen through the biomechanics program, was that he could not transmit 100% of his power. Jung Sung-gon’s physical ability was very good. However, it was recorded that when he continued his pitching motion, his elbows lost strength. Afterwards, Jung Sung-gon corrected the pitching motion and repeatedly measured the record.
Jeong Seong-gon recorded the highest speed of 135 km/h on April 20th. However, on June 15, he threw a fast ball of 149 km / h in live pitching. On the 16th of last month, Jeong Seong-gon said, “I want to throw it quickly (in a real game). I don’t want to show my changed appearance to others. I want to evaluate myself and confirm it.”
Jung Sung-gon appeared in two Futures League games on June 28 and July 2. He pitched two scoreless innings. His four-seam fastball topped out at 153 km/h. The maximum speed of the slider is 136 km/h.
An SSG Future Team official said, “Jeong Seong-gon recorded an average speed of 147 km/h with his four-seam fastball. He handled the hitter with just the power of his four-seam fastball.”
SSG coach Kim Won-hyung met with reporters on the 4th and said about Jung Sung-gon, “I am happy to record high speed in the Futures League. I want to see it in person.” Jung Sung-gon plans to show his ability by climbing the mound for the first team starting from the game he is losing.
