A-Rod banged up from headfirst slide

ST. PETERSBURG, Fla. -- Alex Rodriguez put a charge into his team and gave New York Yankees fans a thrill with his headfirst slide into home plate in Sunday's 5-0 win over the Toronto Blue Jays, but the 40-year-old DH's show of bravado did not come without its price.

The Yankees say A-Rod underwent an MRI on his left knee Tuesday afternoon, which revealed a bone bruise. Rodriguez -- who said "I left it all out there," on the slide after Sunday's game -- is in the lineup for Tuesday night's game against the Tampa Bay Rays.

Joe Girardi has said Rodriguez will get the weekend off when the Yankees play three games against the Mets at Citi Field with no DH. A similar break when the Yankees traveled to Atlanta at the end of August seemed to recharge A-Rod, who hit just .153 with two home runs in August but has rebounded to bat .261 with five home runs so far in September.

"You look at Alex's age, it probably helped him a lot," Girardi said. "It helped him to bounce back a little bit and feel fresh. He's hot right now and we want to keep him that way."

Rodriguez is batting .257 overall with 31 home runs, tied for the team lead with Teixeira, and 82 RBI, second to Brian McCann's 89.
