Willi Castro vs Kevin Gausman

The Almanac's Take

Castro gets the platoon edge here, batting from the left side against Gausman's right arm, and his .269/.331/.407 line across 317 PA this season is a reasonable foundation. Gausman carries a 4.41 ERA and 1.22 WHIP through 20 starts, with 15 homers allowed — the power vulnerability is real — though his 9.3 K/9 and 3.62 K/BB ratio mean he's not easy to barrel consistently. The head-to-head is 14 PA, so treat it as a footnote: 3-for-14 with a homer, 87.7 mph average exit velo, and a pitch mix that's nearly 60% four-seamers and 41% splitters — the splitter usage is worth knowing, given Castro's 27.8% strikeout rate.
