Reddick exits, but 'good to go' post-plunking

OAKLAND -- A's right fielder Josh Reddick had to exit Wednesday's 5-4 win over the Royals on Wednesday after getting hit by a pitch leading off the bottom of the eighth inning, but he said he should be "good to go" for Friday night's series-opener at Seattle.

With the game tied at 4, Kansas City turned to reliever Jose Mijares, who hit Reddick with what appeared to be a breaking ball in the back of his right shoulder, as he turned to avoid getting hit in the face, and the ball caromed into the back of his jaw. Reddick landed hard on the ground and stayed there while trainers examined him.

"The way I went to avoid it, my right arm went up and tried to block my face, but the way it was spinning it kind of came up and hit right off the back of the jaw," Reddick said. "Went down. When I closed my eyes and opened them up, I saw a little bit of spotty light.

"So we just wanted to be safe and get me out of there and just run all the tests. Everything came back great, so I'll take the off day and work out a little bit. Go in there Friday, and I should be good to go."

Reddick walked back to the dugout and was replaced by pinch-runner Coco Crisp.

The A's also lost starting shortstop Cliff Pennington after he fouled a pitch off his left knee cap in the bottom of the sixth, but A's manager Bob Melvin said Pennington should be able to play Friday night. Eric Sogard replaced Pennington in the top of the seventh.
