The noticeable drop in the velocity of his four-seam fastball in the first inning was the first sign that something wasn’t right with Dodgers right-hander Yoshinobu Yamamoto on Saturday night.
The flashing red lights then came in the bottom of the second inning, when reliever Michael Grove began warming in the Dodgers’ bullpen even though Yamamoto had given up only one hit in two scoreless innings against the Kansas City Royals.
Yamamoto, whose start was pushed back two days to give him extra rest after he threw a season-high 106 pitches while shutting out the New York Yankees on two hits through seven innings on June 7, was then pulled after two innings, the team announcing that he was experiencing triceps tightness.
