“(Yoon) Yeong-cheol has a lot of ‘weighted pitches’.”
KIA Tigers coach Kim Jong-guk used the expression ‘weighted pitches’, referring to rookie pitcher Yoon Young-cheol (19), who started against SSG the day before the away game against Doosan Bears held at Jamsil Stadium on the 12th.
‘Weighted pitches’ is a word that indicates the effect that even if a pitcher throws the same 100 pitches, 100 pitches with runners throw more fatigue than 100 pitches with no runners.
As a result of the KIA data analysis team’s analysis, Yoon Young-chul said that he was throwing a lot of balls in the presence of runners. In fact, Yoon Young-cheol had 50 at-bats with runners up until the 12th. The runner-free situation was 52 at-bats. The ratio is almost 1:1 .
On the other hand, Kiwoom Heroes’ Ahn Woo-jin, the league’s top pitcher, had 101 at-bats without runners, more than 66 at-bats with runners. The same goes for NC Dinos Eric Peddy. 111 at-bats without runners are more than 63 with runners. As such, the league’s top pitchers have a 1.8:1
ratio of no runners to runners . Yoon Young-cheol, whose ratio is 1:1, has the task of not creating many situations with runners.
Director Kim said, “Young-chul has a lot of weighted pitches. So he thinks the number of pitches is less than 100.”
Usually, starting pitchers throw 90 to 100 pitches on average, but Yoon Young-cheol has a lot of weighted pitches, so even if he throws only 90 pitches, he has similar fatigue to throwing 100 pitches. For that reason, KIA only entrusted Yoon Young-chul with 90 pitches once, and he gets off the mound before 90 pitches each time. 안전놀이터
Still, manager Kim said, “Yoon Young-cheol is doing well as a fifth starter.” “You are now a 20-year-old rookie. (On the day Yoon Young-cheol starts), he thinks about 5 innings and 3 runs, but he is doing just that,” he smiled.
Yoon Young-cheol started 5 games and recorded 1 win (1 loss) with an ERA of 4.30. Yoon Young-cheol is the only pitcher among the rookies in the 10 professional baseball teams who is in a solid starting rotation.
KIA is nurturing high-end rookies with great care. He analyzes the pitching situation in various ways using data rather than simply matching numbers and manages it carefully accordingly. Under that management, Yun Young-chul is growing up.
