Los Angeles Angels ace Jered Weaver was taken out of Monday's game after just 12 pitches with a lower back injury.
Apparently, Weaver injured his back while throwing a first-inning strike to the Yankees' Robinson Cano.
After delivering the pitch, Weaver jumped off the mound in pain. Manager Mike Scioscia and a trainer came out to the mound, and after Weaver threw a warmup pitch to catcher Bobby Wilson, it was evident Weaver could not stay in the game.
The severity of the injury is unclear, and it's unknown whether Weaver will be sidelined.
Right-hander Bobby Cassevah took Weavers place on the mound.
Weaver (6-1) is having a standout season. He pitched a no-hitter earlier this season, and began the game tied for second in the American League in wins. He entered the game with a 2.61 earned-run average, which is among the league leaders. Opponents were hitting just .190 against him.
However, he left Monday's game with his team trailing 1-0, and he failed to retire any of the three batters he faced. Derek Jeter and Curtis Granderson singled, and Alex Rodriguez reached on an error, allowing Jeter to score.
Cassevah came in to face Cano, the cleanup hitter, with the count 1-1 and struck him out, but the Yankees scored two more runs in the inning to take a 3-0 lead after half an inning.
Weaver will not be the losing pitcher, though, because the Angels scored four runs in the bottom of the first.
