The Los Angeles Dodgers’ superstar signing from the Japanese league, Yoshinobu Yamamoto, wrapped up his final spring appearance yesterday as the Dodgers lost 8-1 to the Mariners. The next step for this star-studded Dodgers team is the Gocheok Sky Dome in South Korea, where they will play the San Diego Padres in MLB’s opening regular season series, beginning on March 20. Yamamoto is scheduled to start the second and final game of that series, and his major league debut is as excitedly anticipated as any in recent memory.
On February 28, Yamamoto started off his spring as flawlessly as the Dodgers organization could have asked for, pitching two scoreless innings and striking out three against the Texas Rangers. Since then, though, he has struggled dearly, pitching to a 10.57 ERA and 2.35 WHIP in 7.2 innings. Those back-to-back poor outings have raised concern amongst certain members of the baseball community, which has now has us all asking the important question: How worried should the Dodgers be about Yamamoto’s struggles this spring?
To answer this question, let’s take a closer look at what exactly went right and wrong for Yamamoto this spring:
What went right: Yamamoto, as promised, was a strikeout machine this spring. In 9.2 Innings, he struck out 14 batters, and his strike percentage was .800. Another thing that went right for Yamamoto this spring was his ability to deceive hitters the first time through the order. In his most recent outing against the Mariners (where he ended up getting hit pretty hard), he started off the game exceptionally well, striking out five batters through three shutout innings, including striking out the side in the first. After that, though, things went downhill quickly.
What went wrong: As his second and third starts went on, Yamamoto’s command got increasingly worse, and the amount of hard contact he gave up went up exponentially. In his two outings after his impressive debut against Texas, hitters hit .389 against him. This seems like a common issue amongst pitchers coming from a different professional league over to the MLB, as there aren’t hitters of this quality anywhere else in the world.
