Winn (forearm) was reinstated from the 15-day injured list ahead of his start against the Rangers on Sunday, Shayna Rubin of the San Francisco Chronicle reports.
The right-hander landed on the shelf in mid-May with a forearm strain, but he'll rejoin the Giants' rotation after being sidelined for less than a month. Winn delivered three straight quality starts in April but struggled in his final three outings before going to the injured list with 17 runs allowed and a 5:5 K:BB over 8.1 innings.
