Jason Giambi could resume running outside today.
Giambi, who is recovering from a benign tumor in Tampa, suffered a groin pull Tuesday and shut down his rehab, but ran in an indoor pool yesterday and did an upper-body workout, too. “We haven’t had any setbacks,” Giambi told The Associated Press. "(Today) is a big day.” He is still hoping for an early September comeback to New York, but he may not be back until mid-September at this rate.
