The Giants placed Mahle on the 15-day injured list Friday, retroactive to Wednesday, due to a left hamstring strain, Justice delos Santos of The San Jose Mercury News reports. Mahle may have tweaked his hamstring during his last start Tuesday against the Diamondbacks, when he allowed three runs on three hits and three walks while striking out three across five innings, taking his seventh loss of the season in the process. He's eligible to be reinstated from the IL in mid-June, but the Giants will have a better sense of Mahle's recovery timeline once he undergoes further tests on his hamstring. Logan Webb (knee) was reinstated from the 15-day IL in a corresponding move, but with Mahle now sidelined, the Giants may call up a starter from Triple-A Sacramento if they wish to maintain their six-man rotation.

Tyler Mahle: Breaking News
Takes third straight loss
Mahle allowed three runs on three hits and three walks while striking out three over five innings to take the loss versus the Diamondbacks on Tuesday. Mahle has allowed three or more runs in five of his last six starts, but he has covered at least five innings in each of those games. While he's eating innings, he's now six starts removed from his lone win of the year, taking four losses in that span. Mahle has a 6.04 ERA, 1.54 WHIP and 57:24 K:BB through 56.2 innings over 11 starts on the year. The veteran right-hander as partially benefited from a favorable home park -- he has a 3.90 ERA at home compared to an 8.88 ERA on the road. Mahle's next outing is projected to be at Milwaukee.
Handed sixth loss
Mahle (1-6) took the loss Wednesday against the Diamondbacks after giving up six runs on eight hits while walking none and striking out six across five innings. Mahle was in decent shape Wednesday until the fifth inning, when Arizona scored thrice on four hits to take the lead for good. It marks Mahle's third straight outing allowing four or more runs to elevate his ERA to 6.10 through 10 starts this season. His six losses are tied with six others for the most in MLB. The 31-year-old is projected for a home rematch against the Diamondbacks next week.
