The right-handed pitcher threw 7 innings, only giving up one run in a win against the Colorado Rockies before his start on Monday.But he also allowed 8 runs on 11 hits against the Toronto Blue Jays earlier in the month of July.Overall, McDonald currently holds a 3-7 record with a 5.12 ERA. He has tallied 57 strikeouts to 23 walks through 70 1/3 innings.After the Giants’ roster move, Alex Pavlovic of NBC Sports Bay Area believes that “Carson Whisenhunt is the likely choice to fill that spot in the rotation.”The left-handed pitcher has performed admirably in two starts with the big league club. He is 2-0 with a 3.38 ERA. Whisenhunt also ranks as one of the best pitching prospects in the Giants’ farm system.GettySAN FRANCISCO, CALIFORNIA – JULY 09: Carson Whisenhunt #88 pitches against the Colorado Rockies at Oracle Park on July 09, 2026 in San Francisco, California.
