TAMPA, Fla. (AP) - New York Yankees reliever Joba Chamberlain expects to be out of a walking boot for an injured ankle in about two weeks.

Chamberlain dislocated his right ankle bouncing on a trampoline with his son on March 22. The right-hander has resumed working out at the Yankees' Minor League complex, where he played catch in the outfield Friday with his right knee on a stool.

Chamberlain said the ankle continues to improve and that his throwing arm is 100 percent. The 6-foot-2, 240-pound right-hander was working his way back from elbow ligament replacement surgery and was expected to return in June.

Also, Andy Pettitte made 66 pitches over 5 2/3 innings in an extended spring training game. The left-hander, who ended a one-year retirement last month, said he expects to pitch at a higher classification, likely Double-A Trenton, in his next start.
