In this WBC, Korean pitchers had a hard time adapting to the WBC official ball. It was slippery and had a lower seam than the official ball of the KBO League, so it often fell out of the hand. During the WBC tournament, pitchers who were said to be very good were sometimes seen throwing balls that fell out.
Foreign pitchers use such a ball before throwing a new official ball in Korea. Most foreign pitchers quickly adapt to the Korean official ball, which is easy to grip, and show satisfaction. However, KT Wiz’s new foreign pitcher, Bo Shul-seo, says he is still adjusting to the official ball.
He says the changeup is a problem. On the 24th, in an exhibition 스포츠토토game against the LG Twins held at KT Wiz Park in Suwon, Schulser started and recorded 4 hits, 4 strikeouts and 1 run in 4 innings. Four dunes are three.
He threw 59 of them, including a 150 km fastball, a 142 km cutter, a 135 km changeup and a 127 km curveball.
When I asked Schulser how the KBO League official ball was, he said, “I feel a big difference in the changing ball.” Schulser said, “I use a split changeup that catches the changeup with my fingers open.”
Shulser mainly uses fastballs of over 150 km, cutters and changeups that fall slightly. The 4th pitch is a curve. Schulser said, “I like the straight ball and the cutter, and the curve is also good because it has good spin.” In the United States, the difference between my fastball and changeup rotation speed is over 1,000, but this is not the case in Korea. You have to adapt,” he said.
Schulser, who was mainly active as a bullpen pitcher in the United States, said that that’s why he pays a lot of attention to body care. Schulser said, “I’ve never pitched 140 or 150 innings in the US, but I have to do a lot of innings here this year. That’s why stamina seems to be very important.” “KT’s training coaches are taking good care of me. The program has been of great help to me.”
