Giants center fielder Angel Pagan’s MRI showed brusitis on his injured hamstring, reports Andrew Baggarly of CSN Bay Area.
MRI on Pagan showed bursitis, Bochy said. He’ll do light activities. Might be available to pinch hit.

Pagan has been out since his miraculous home run on Saturday, with Gregor Blanco starting in center and Andres Torres getting the regular duties in left.
The fact that he may be available to pinch-hit makes me optimistic that Pagan will start when the A’s series moves to AT&T Park tomorrow.
Pagan hasn’t been spectacular in the first year of his four-year contract. His .314 OBP is below his career average, and Pagan has been successful on just six of his ten steal attempts. Combine that with bad route-running in the outfield and the results have been underwhelming.
Take that last paragraph with a grain of salt. Pagan’s BABIP is .286, which should normalize toward his career total of .316. I believe Pagan will earn every dollar of his contract in the first two seasons of his deal, though it may be a drain on the Giants economy in years three and four as his speed evaporates.
