Giants Falter Early in Series Opener Against White Sox

The San Francisco Giants returned to Oracle Park on Friday night looking to bounce back after being swept by the Arizona Diamondbacks , but instead opened their three-game set against the Chicago White Sox with a disappointing 9-4 loss. Coming off an off day on Thursday, the Giants turned to rookie right-hander Trevor McDonald, while Chicago countered with Davis Martin. San Francisco struggled in nearly every phase early in the contest as the White Sox broke the game open with a nine-run fourth inning that ultimately put the game out of reach.

McDonald Suffers Toughest Start of Season McDonald entered Friday having impressed across his first few starts of the season, carrying a 2-0 record and a 2. 37 ERA after a strong outing against the Athletics in which he allowed just one earned run over 6 2/3 innings. Against Chicago, however, the young starter never settled into a rhythm.

The right-hander lasted only 3 2/3 innings, surrendering seven earned runs on three hits while walking one and striking out four. He threw 66 pitches before being lifted during the disastrous fourth inning. According to Baseball Savant metrics, McDonald leaned heavily on his sinker, throwing it 47 times while mixing in 13 sliders and six changeups.

His velocity dipped slightly compared to previous outings, with his fastball averaging roughly one mile per hour below his season norm. He generated eight whiffs on 30 swings overall, finishing with a 27 percent whiff rate. Despite flashing swing-and-miss ability, Chicago capitalized on mistakes left over the plate and consistently pressured the Giants defensively throughout the inning.
