1.) Joba Chamberlain threw "really well" in his first minor league rehab inning, Brian Cashman said.
"This was Day 1 of a 30 day rehab program," Cashman said.
Chamberlain hit 97 on the gun in his one inning of no-hit, two-strikeout, one unearned run baseball.
2.) Cashman said he hasn't been told by anyone that Mariano Rivera could return.
"No," Cashman said when asked if there is a chance Rivera pitches again in '12. "I've been told he is done for 2012."
