The Giants' Tyler Mahle returns from the injured list (hamstring) to start against the Athletics. He walked five in his only Triple-A rehab start. Before the injury, Mahle compiled a 6.04 ERA. The 31-year-old has seen a dip in velocity, and I like the Athletics to jump on him. Back them to even this series.

Sorry for the pun - but I was Jump-ing at the chance to bet the Athletics on Wednesday night. The A's have won all four of rookie Gage Jump's starts in June and he's pitching to a 1.42 ERA this month. On the other hand, Tyler Mahle comes off the Injured List to start for the Giants and he's been miserable in 2026 with a 1-7 record and 6.04 ERA. Look for the Athletics to even the series in San Francisco after a 3-1 loss in the opener on Tuesday.
