Last night, Jerry Hairston Jr. conducted a clinic on how to handle the aftermath of committing a devastating error. First, he stopped the first reporter he saw — WFAN’s Sweeny Murti — and told him, “I know you guys want to talk to me. I’m going to get something to eat and I’ll be right back.”

Then, when he emerged, Hairston literally invited the media to his locker with a wave. And he answered every single question.

“He knows you have to be accountable,” Derek Jeter said. “Everyone makes mistakes. That’s one reason it’s so hard to throw a perfect game.”

Pettitte also reassured Hairston, joking that he didn’t want to throw nine innings anyway. Posada said everyone felt bad for “J-Hair.”

“Jerry’s been outstanding,” Jeter said. “He’s playing everywhere, the infield, the outfield, and he’s catching between innings. I don’t think people appreciate how difficult that is.”

Speaking of Jeter, he is the Yankees nominee for the 2009 Roberto Clemente Award, which annually recognizes the player who performs exceptionally on the field and contributes in the community.

Johnny Damon: Told Damon today that I could not say “calf cramp” on yesterday’s pregame. He laughed. Much more significantly, Damon paid a “very rewarding” visit to Walter Reed Army Hospital today, part of his ongoing commitment to the Wounded Warrior Project. Swisher, Robertson and Coke went along. Johnny was particularly touched by a young quadriplegic he has seen on several visits. “I see the progress he’s making,” Johnny said. “And he has a great spirit, a great sense of life. Definitely, he’s an inspiration.”

Alex Rodriguez: He’s back at third tonight and this morning, Alex spoke to 500 student-athletes at Millford Mill Academy in Baltimore County about the dangers of performance-enhancing drugs. According to a news release, Alex opened his remarks: “As a kid, my favorite player was Cal Ripken, Jr. Has anyone here heard of him?”

The man knew his audience. Alex went on to say he made a mistake and “one of my missions in life is to turn a negative into a positive.” He called his admission of steroid use “pretty darn liberating.”

The call-ups: Francisco Cervelli, Ramiro Pena, Mark Melancon, Edwar Ramirez and lefty Mike Dunn. As you would imagine, they were smiling a lot in the clubhouse.

Adam Jones: The young Oriole center fielder hates to lose, which will be important as he becomes a leader on a Baltimore team that is trying to rise from the ashes. And Jones wasn’t thrilled last night to see Yankees fans taking over Camden Yards. “We’re not at the new Yankee Stadium,” Jones said. “I expect more of our fans to be here, but I understand completely why they’re not. But it (stinks) that they’re not.”

Jim Thome: Had a chance to interview him for Saturday’s “Batting Practice Today presented by Audi” when the White Sox were in town. No wonder he’s considered one of the friendliest players in the game. Anyway, today on WFAN, Dodgers GM Ned Colletti was interviewed by Adam the Bull and Jon Heyman. Colletti said Thome wanted to make sure he was upfront in telling the Dodgers he did not think he could play first base for them. No matter. The Dodgers want his bat and his leadership, which could pay off big.
