Wilkerson leaves with concussion after hitting wall

ARLINGTON, Texas -- Texas Rangers left fielder Brad
Wilkerson left Thursday night's game against Baltimore with a mild
concussion after catching a flyball and then crashing hard into the

After the game, Wilkerson said he had a dull headache and a sore
right shoulder -- the same one that bothered him last season in
"I'm kind of worried about it, but I'll wait until (Friday) to
see what's going on," Wilkerson said.
Wilkerson also hit his face on the wall that includes metal
grates protecting the out-of-town scoreboard. He slammed into it so
hard that he knocked a panel out of the scoreboard.
"I haven't hit a wall that hard," Wilkerson said. "The ball
got up on me quick. ... I was at full speed."
Wilkerson's catch in the fifth inning started a strange
inning-ending double play. Drew Meyer pinch hit for Wilkerson in
the bottom of the inning.
Nick Markakis hit the ball that Wilkerson tracked down. While
Wilkerson sat dazed on the warning track, Corey Patterson never
tagged up from first base.
"For about 5 seconds there, I was `what? what?'," Wilkerson
Orioles manager Sam Perlozzo said Patterson wasn't sure if the
ball had been caught.
Center fielder Adrian Brown asked for the ball, but Wilkerson
got up and threw it to second baseman Mark DeRosa. Patterson was
tagged when he stopped a couple of steps shy of second base after
wandering between the bases while Wilkerson was down.
Wilkerson was 2-for-2 and scored twice. He is hitting .440
(11-for-25) during a seven-game hitting streak that has raised his
average 60 points to .255.
