Yankees rookie sensation Joba Chamberlain was suspended for two games and fined $1,000 Friday, a day after he threw two 98-99 mph pitches over the head of Boston's Kevin Youkilis.

Chamberlain, ejected by plate umpire Angel Hernandez, claimed the ninth-inning pitches slipped and "there was no maliciousness or bad intention."

The umpires disagreed.

"There's more than a little bit of history between these clubs," crew chief Derryl Cousins said. "Those were two pretty nasty pitches the young man threw. Up here, you need to be a little better throwing strikes, and we just had to put a lid on it before there was a problem."
