2026 Fantasy Outlook
After a three-inning with San Francisco appearance to close the 2024 campaign, McDonald spent most of last season with Triple-A Sacramento before joining the Giants for the final two weeks. With the River Cats, his command and control slipped from prior levels, and he was hit particularly hard. McDonald leans heavily on a sinker and slider, while occasionally mixing in a four-seamer and changeup. He appeared three times for the Giants, starting twice and totaling 15 innings with 14 strikeouts and two walks. San Francisco has several options for the back end of the rotation, which could push McDonald toward a bullpen role. To secure a spot, he'll need to regain his command and control. He's best suited as a swingman, where he could be effective when starting at home. Read Past Outlooks
Signed a one-year, $780,000 contract with the Giants in March of 2026.
Takes loss Saturday
McDonald (2-4) allowed four runs on six hits, three walks and a hit batsman while striking out four over 3.2 innings to take the loss versus the Cubs on Saturday.
Analysis
McDonald didn't get much support from his teammates, but he struggled through this outing as well. It took him 92 pitches (53 strikes) to collect his 11 outs, matching his shortest start of the season. McDonald is now at a 4.64 ERA, 1.29 WHIP and 41:15 K:BB over 42.2 innings through eight starts. It's not clear when Tyler Mahle (hamstring) will return from the injured list -- if he can't go next week, McDonald is projected for a road start versus the Marlins.
