Jung Woo-young, who debuted in 2019, took the Rookie of the Year title with a sinker that quickly curves toward the body of a right-handed hitter, and has grown into the league's best bullpen by increasing his speed.
He averaged 143.57 km in 2019 and is 151.24 km this season, a whopping 8 km in three years.
Last month he hit 157km/h, the fastest speed ever.
Among the major league sidearms, Justin Lawrence of Colorado is the only pitcher with a faster sinker than Jung Woo-young.
Last winter, I increased my weight by 14 kg and muscle mass by 5 kg due to severe weight training, which led to a rapid improvement in speed.
