Joba Chamberlain rejoined the Yankees on Aug. 1, but he didn't resemble the flame-throwing reliever they had been looking for all season.

A month later, he may be.

Chamberlain had one of his most dominant — and important — outings in years in yesterday's 13-3 win over the Orioles. He pitched 1 ²/3 hitless innings and tied a career high by striking out four in a relief appearance, matching the number he had on Sept. 21, 2007 in Toronto.

And this time, it came at a critical point in the victory.

"It was a big turning point in the game," said Chamberlain, who bailed out Freddy Garcia after the veteran fell apart in the fourth.
