Joe Girardi understood when he took the job as Yankees manager in October 2007 that his aging stars, players that define a historic era and he once called teammates, would retire under his watch if he stayed long enough.

In 2012, it was Jorge Posada. Last year, it was Mariano Rivera and Andy Pettite. Only Derek Jeter remained this season. And before Jeter clicked “post” on Facebook Wednesday afternoon, Girardi believed Jeter would delay his departure beyond 2014.

“I had not heard before that,” Girardi said of Jeter’s decision to retire after this season. “So I think we were all a little bit taken aback by it. You’re never sure how someone’s going to do it, but I had no inkling that that’s what he was thinking.”

Now, Girardi must oversee another farewell tour that already has the secondary ticket market for Yankees games, home and away, soaring. Girardi’s arrival in Florida was delayed until Friday due to the snowstorm in the northeast so he had only communicated with Jeter via text message. He planned on meeting with Jeter in person, but emphasized the looming retirement will not alter his plan for the shortstop.

Ideally, Girardi said, Jeter will bat second as he has for the majority of his career. But ultimately, Jeter, who turns 40 in June, will have final say in whether he plays in a game and whether it’s at shortstop or as the designated hitter.
