Mark Trumbo capped a big night with a walk-off home run in the bottom of the ninth to give the Los Angeles Angels a 9-8 victory over the New York Yankees Monday night at Angel Stadium in Anaheim. The home run was one of three hits for Trumbo, who fell just a single shy of the cycle.

It was the third career walk-off home run for Trumbo and his second career game with three extra-base hits.

But the story after the game was the same as the story at the beginning of the game: the health of Jered Weaver. The Halos' ace left after throwing just 12 pitches in the first inning. He allowed a pair of singles followed by a potential double play grounder that was booted by Erick Aybar. Then on his first pitch to Robinson Cano, Weaver suffered a back injury.

"As I released the ball, I couldn't bend over," Weaver said. "It felt like somebody came up from behind and stabbed me."

Weaver, who felt stiff after the game and still could not move around much or bend over, will have an MRI exam on Tuesday morning. Even if the Angels don't need to make a roster move for Weaver, they might need to add a pitcher before Tuesday's game as their bullpen was taxed in relief of Weaver.

"We're going to look at a couple of things tonight and tomorrow, and see what we need. We had a lot of innings out of our pen tonight," said manager Mike Scioscia on possibly dipping into the minor leagues for a pitcher or two. "We have some arms down there that we'll consider."

The win was the seventh straight for the Angels, and moved them to .500 for the first time since the second game of the season. Did reaching the break even point have any significance to manager Mike Scioscia?

"Absolutely none," he said after the game, as the Angels remain six and a half games behind the Texas Rangers in the American League West.
