Joba Chamberlain has some poor postseason luck.

In 2007, he was swarmed by midges in Cleveland. On Thursday, he was drilled by a bat shard.

Pitching in relief in the 12th inning of Game 4 of the Yanks-O's ALDS, Chamberlain was drilled by a Matt Wieters bat shard and had to be removed from the game.

Chamberlain pitched a scoreless 11th and started the 12th against Wieters. He broke Orioles catcher's bat with his second pitch -- a 93 mph fastball. The ball landed in left field for a single, but the bat shard flew back at the mound and hit Chamberlain in his elbow -- the same elbow that was repaired by Tommy John surgery.

Chamberlain was in immediate discomfort. The elbow swelled up significantly. He attempted a few warmup pitches but Joe Girardi chose to remove him from the game.

The Yankees announced that Chamberlain suffered a contusion to his right elbow. X-rays were negative and Chamberlain will be re-evaluated on Friday.

Rookie David Phelps replaced Chamberlain, making his first postseason appearance.
