Giants' Ramiro Pena: Diagnosed with ankle sprain

Pena has been diagnosed with a sprained ankle, Alex Pavlovic of CSN Bay Area reports.

Analysis:

A collision with Mac Williamson in shallow right field Wednesday left Pena limping, but an MRI revealed no structural damage. The Giants will have to play a man down for a little while, with Pena expected to need 5-to-7 days before returning to the field, although there's some hope he will be available to pinch hit at some point this weekend.
