Joe Girardi said the switch from Travis Hafner to Lyle Overbay yesterday in the DH spot was nothing more than giving Hafner a day off. However, it was hard to ignore Hafner’s 5-for-53 (.094) funk and .219 average going into yesterday’s 6-2 loss to the Angels at Angel Stadium. “Get Lyle in there, I will probably get Haf back in there [today],’’ said Girardi, who also rested Vernon Wells’ frigid bat and played Thomas Neal in left field. “Just giving [Hafner] a day.’’ Asked whether Hafner, who had a shoulder problem earlier this season, was sound physically, Girardi indicated he was. “He hasn’t said anything,’’ the manager said. Overbay went 0-for-4 and had three of the Yankees’ season-high-tying 14 strikeouts. Neal fanned in all three of his at-bats. Because Girardi’s DH options are limited, the manager said he and his staff hadn’t discussed reducing Hafner’s playing time. “It’s not something we talked about, and I believe Haf is going to hit,’’ said Girard. “It’s not something we considered. Up until this point we consider him to be our DH. You look at things as things go on and you make evaluations.’’ Overbay, yesterday’s DH option, had three hits in 16 at-bats since Mark Teixeira returned from the DL May 31 and isn’t the power threat Hafner is, though Hafner has hit just two homers since May 20. Wells is in an 8-for-77 (.104) slide.
