White Sox 6, Mariners 1: Vargas Homers Twice Off Castillo

The lead

May 9, 2026 - Chicago - The Chicago White Sox reset their weekend after a bumpy week. Miguel Vargas homered twice, drove in three runs, Colson Montgomery also connected, and Chicago beat Luis Castillo and the Seattle Mariners 6-1 on Saturday night, per the Associated Press recap embedded on CBS Sports.

Anthony Kay (2-1) allowed one run over five innings as the White Sox improved to 18-21—a far cry from 11-28 after 39 games a year ago, per AP.

How the game turned

Vargas carried the middle of the order against a Mariners club that had taken the series opener 12-8 Friday. Seattle’s offense managed only four hits; Julio Rodríguez accounted for two of them as the rest of the lineup stayed quiet behind Castillo’s short outing.

Castillo (0-4) surrendered four runs on five hits in four innings during his third straight loss, striking out six without issuing a walk—a sharp K/BB line that still couldn’t contain the long ball.

Pitching and matchup notes

Kay’s five-inning stint kept the game in the White Sox’s hands early, letting the pen protect a manageable lead built on power rather than small-ball prolonged rallies. Seattle will eye Sunday’s matchup hoping for length after burning innings in Friday’s shootout.

Bats that changed the board

Vargas’s two homers and Montgomery’s deep drive supplied the separation; the White Sox didn’t need a 20-hit night—just a handful of swings that moved the scoreboard while Castillo pitched in leverage counts.

AthX Engine fantasy angle

Chicago’s 14 AthX Engine team FP on May 9 landed sixth among clubs, with Miguel Vargas’s 13 hitting FP tying him near the top of AthX Engine’s daily hitter board. Multi-homer games from middle infield types still spike fantasy output quickly on slates without historic team totals. AthX Engine differs from dynamic pricing.

What comes next

Sunday’s series finale offers Seattle a chance to salvage a split and Chicago an opportunity to string another winning push after snapping a stretch of three straight losses.
