“I want to see it in person.”

The SSG Landers called up Sung-geon ahead of the rain-canceled game against the KIA Tigers at SSG Landers Field in Incheon on April 4.

Jeong was drafted by the KT Wiz with the 14th overall pick in the second round of the 2015 KBO Rookie Draft. He played for KT until the 2019 season and completed his military service with the Sangsang before moving to SSG via trade in the 2022 season.

Jung appeared in just two games last season, allowing three runs (three earned), one hit (one home run), four walks and three strikeouts in 2⅔ innings with a 10.13 ERA. His four-seam fastball only averaged 135 km/h. It’s a far cry from his mid-140s fastball in KT.

This season, Jeong changed his pitching mechanics using sports science at the Future Team. He was initially against the idea of changing his pitching mechanics, but after seeing the changes, he became positive about it.

His problem, as identified by the biomechanics program, was that he couldn’t deliver 100% of his power. His physical performance was very good, but he was losing power from the elbow as he continued his pitching motion. He modified his pitching motion and took repeated measurements.

On April 20, Jung recorded a top speed of 135 km/h. However, on June 15, he threw a fastball of 149 km/h in a live pitching session. On June 16, Jung said, “I want to throw quickly (in a live game). I don’t want to show other people how I’ve changed. I want to evaluate myself and check myself.”토스카지노

Jung made two appearances in the Futures League on June 28 and July 2. He pitched two scoreless innings. His fastball topped out at 153 km/h. His slider topped out at 136 km/h.

A representative from the SSG Future Team said, “Jung-geon had an average fastball velocity of 147km/h with his four-seam fastball. He was able to handle hitters with just the power of his fastball.” “Not only his fastball, but also his angle and delivery have improved a lot,” he said.

SSG manager Kim Won-hyung met with the press on the 4th and said about Jung Sung-gon, “I’m happy that he recorded a high velocity in the Futures League, and I want to see it myself.” “A pitcher’s velocity increase leads to confidence. It should be seen as a competitive advantage.” Jeong plans to showcase his abilities by taking the mound for the first team from games he is losing.
