What happened: Detmers paired his curveball with a four-seam fastball to challenge hitters across vertical and velocity bands.
Why it matters: The shape-and-speed contrast forces hitters to protect multiple parts of the zone. That gives Detmers another sequencing option after establishing the fastball.
By the numbers: Detmers worked six innings with six strikeouts, one earned run and three hits allowed. His curveball averaged 118.8 km/h with a 66.7% CSW, separating from his four-seamer by 79.4 cm vertically and 32.7 km/h in velocity.
What to watch: His next start will test whether that pitch separation continues to generate swings and misses.
