Derek Jeter says he still gets goosebumps during player introductions for the All-Star Game. That’s cool.

So is this: The second half of the season is officially underway in the Bronx.

Sergio Mitre: He’ll make the start Tuesday. Aceves is too valuable in the bullpen and will stay there. You definitely get the feeling the No. 5 spot in the rotation might be Sergio’s for a while.

Chien-Ming Wang: He’s scheduled to play catch Sunday or Monday, Girardi said. This might be a lost season for Wang, who’s logged just 42 innings in nine starts and 12 appearances this season.

Joba Chamberlain: He said his four-day break spent in Nebraska was perfectly relaxing. When he asked about ours, we told him we spend 20 hours (on WFAN’s midday show with Adam the Bull) talking about him. Joba shook his head and laughed.

Phil Hughes: Girardi says he’s comfortable with the rotation and believes Pettitte and Joba each will have a big second half. He said he’d become concerned about the rotation if the Yankees were to lose CC or AJ to injury. (Uh, yeah, you’d think so.) Anyway, it would only be under such a dire scenario that Hughes would return to the rotation this sea son. At least that’s how things stand today. Hughes owns an ERA of 0.98 in 13 relief outings.

Mike Mussina: He’ll be here for Old Timer’s Day. Wow, an old timer. We’ll have ask Mussina how that sounds.

Al Leiter: He brought Mike and Ikes to the booth! And Twizzlers. Nice.

Tino Martinez: Hey, maybe he’ll be here for Old Timer’s Day! We’ll corner him with your (very old) questions.
