Previewing the Key Matchups Against the White Sox Starters

As one of the most pivotal series of the season approaches, the focus intensifies on how the White Sox perform against the pitching arsenal of the team’s top starters. With three pitchers set to take the mound against Chicago, understanding their strengths and weaknesses becomes essential.

Starting off with Gavin Williams, who is slated to pitch tomorrow, it’s clear he’s been facing challenges lately, boasting an ERA of 4.65 over his last 10 starts. His fastball usage has seen a significant decline, dropping from 28.5% in April to just under 10% in June. Instead, he has leaned heavily on his curveball, sinker, and sweeper this month, incorporating a mix of cutters and four-seamers as well. Analyzing his pitch usage reveals that his curveball, which typically ranges between 80-84 mph with a vertical drop of 11-15 inches, has yielded varying results against White Sox hitters. For instance, Jacob Gonzalez stands out with a .907 xwOBA against it, while Braden Montgomery has managed only a .040 xwOBA.

When it comes to his sinker, which ranges from 95-97 mph with a notable armside break, several players have shown susceptibility. Andrew Benintendi, for example, has an xwOBA of .567 against this pitch, while Sam Antonacci has a .370 xwOBA. Conversely, Gavin’s sweeper, thrown at 86-88 mph, has proven effective, with hitters like Austin Hays failing to register any expected weighted on-base average.

Next up is Parker Messick, who has maintained a consistent pitch usage throughout the year, primarily utilizing his four-seam fastball, changeup, and sinker about 70% of the time. His four-seam fastball, clocking in at 92-95 mph with a vertical break of 15-18 inches, has seen mixed results against the White Sox lineup. Randal Grichuk, a right-handed specialist, has particularly excelled against it with a .731 xwOBA. Meanwhile, his changeup and sinker have also shown potential for success, especially if he can achieve precise location.

Finally, Tanner Bibee has altered his approach in recent months, focusing on fastballs—sinker, cutter, and four-seam—while largely sidelining his breaking balls. His sinker, ranging from 92-96 mph, has impressed against hitters like Chase Meidroth, who has posted a .268 xwOBA. However, it will be crucial for Bibee to avoid same-handed sinkers and possibly reintroduce his curveball to navigate through the young White Sox lineup effectively.

As the series unfolds, the ability of these pitchers to adapt their strategies and exploit the weaknesses of the White Sox hitters will be instrumental in determining the outcomes.
