Fans 10 in first career win
PSan Francisco Giants
September 26, 2025
McDonald (1-0) allowed three runs on five hits and struck out 10 without walking a batter over seven innings to earn the win over the Rockies on Friday.
Analysis
McDonald gave up a three-run home run to Ezequiel Tovar in the fifth inning but was otherwise quite stingy in a dominant win. This was McDonald's third appearance in the majors this year, and he finished the campaign allowing six runs over 15 innings while adding a 14:2 K:BB. It was a strong showing in his late-season audition, which reflects better than his 5.37 ERA, 1.45 WHIP and 144:62 K:BB over 142.1 innings at Triple-A Sacramento. McDonald has likely done enough to be in the conversation for a big-league rotation spot in the spring.

2024 Fantasy Outlook
McDonald is a nice sleeper prospect for dynasty leagues, as he has excellent control and could potentially get to pitch half his games in the pitcher-friendly park in San Francisco. In his age-22 season, McDonald logged a 1.33 ERA, 0.93 WHIP and 51 strikeouts in 47.1 innings across 14 appearances in the lower levels of the minors. He averaged 94 mph with his two-seam fastball last year (touching 98 mph) and had a groundball rate north of 70 percent. McDonald also sports a plus curveball, while mixing in a four-seamer and a slider.
