Bombers bits

• Yankees manager Joe Girardi said that he does not have any concerns about David Robertson's velocity. Robertson will begin his tenure as the club's closer on Tuesday, and a New York Post report suggested that the right-hander's velocity has been 88 to 90 mph this spring, down from his usual 92-93 mph.

"That's not what we had on our gun," Girardi said. "We have him up to 93 and a lot of 91s and 92, which is pretty normal for David Robertson."

• The Yankees have until Tuesday to make a 40-man roster move to accommodate infielder Yangervis Solarte, according to general manager Brian Cashman. They will place infielder Brendan Ryan (pinched nerve) on the 15-day disabled list to make room on the 25-man roster for Solarte.

Andy Pettitte was in the Yankees' clubhouse on Monday and threw batting practice to the final group of hitters. Pettitte lives in nearby Deer Park, Texas, and will be part of an on-field ceremony to honor Derek Jeter on Wednesday.

• Infielder Dean Anna wore No. 93 during Spring Training, but has switched to No. 45. Anna, a product of Frankfort, Ill., said that he picked the number to honor Michael Jordan. No. 23, of course, has been retired by the Yankees for Don Mattingly.
