Outlook Luis Castillo

Luis Castillo aims to halt late-season slump amid division race

Castillo has stumbled over his last two starts, surrendering 10 earned runs over eight innings for an 11.25 ERA and 2.13 WHIP. Despite these pitching woes, he remains locked in as the number two starter for a first-place White Sox club (75-68) fighting to stay atop the AL Central. Chicago needs the veteran right-hander to quickly locate the strike zone to protect their postseason positioning.

This brutal stretch has inflated Castillo's season ERA to 5.73, falling well short of our projection of a 3.76 ERA and 1.19 WHIP. His strikeout rate has dropped to 8.01 K/9 alongside a bloated 1.49 WHIP, indicating that his second-half decline is driven by hittable fastballs rather than mere misfortune. While he has flashed occasional dominance, his current baseline is far too volatile to rely on.

Chicago hosts Pittsburgh before traveling to St. Louis this week, yet Castillo is not currently listed as a confirmed probable starter. With zero confirmed starts locked into our weekly data and major ratio risks hanging over his profile, fantasy managers cannot gamble on him in championship weeks. Sit.

Outlook Zac Thornton

Zac Thornton looks to rebound in the Bronx following a bumpy stretch

Thornton stumbled in his last outing on September 5, surrendering six earned runs and four homers to elevate his 30-day ERA to 5.00 across five starts. Despite the recent bump, the rookie remains locked in as the number two starter in the rotation for the fifth-place Mets (65-78). His pinpoint control has endured throughout the rough patch, yielding just one walk over his last 16 frames.

Regression has inevitably caught up with Thornton after his sparkling sub-3.00 mark earlier this summer, settling his season ERA at 3.91 with a 1.28 WHIP through nine career starts. While giving up loud contact is a concern, his outstanding 15:1 strikeout-to-walk ratio over the past two weeks shows his command remains pristine. Expect him to settle in as a dependable mid-rotation stabilizer rather than the dominant ace he resembled in July.

Thornton is slated for a single outing this week on Saturday when he visits the Yankees to duel Will Warren (4.24 ERA). Our projections anticipate 6.1 innings of modest run prevention with roughly 4.5 strikeouts, but pitching in the short-porch confines of Yankee Stadium right after coughing up four long balls makes him an uneasy play. Sit.
