MINNEAPOLIS -- Yankees first baseman Mark Teixeira spent Monday in Tampa, Fla., increasing his baseball activity workload as he attempts to return from a Grade 1 left calf strain.
Teixeira sustained the injury while running the bases in an Aug. 27 game against Toronto. He returned for a Sept. 8 game against the Orioles but suffered a setback.
"He did a bunch of work in Tampa today, which is a good sign," manager Joe Girardi said. "He ran the bases -- not at full speed. He did ground balls, and his BP and came out pretty good."
General manager Brian Cashman previously set New York's game at Toronto on Thursday as a target for Teixeira's return, but Girardi stopped short of confirming that on Monday. The manager also acknowledged that the artificial surface at Rogers Centre could delay Teixeira's return.
"I don't know," Girardi said. "The concern is that you rush him and he has that one play and you know he's probably done for the season."
