    Kolek had a rough June 21 outing against St. Louis (JJ Wetherholt hit two early homers), but zoom out: a 1.59 ERA and 1.01 WHIP over 38 innings before that game. He throws six pitches and has an 88th-percentile Fastball Run Value, which is what drives the groundball-heavy approach behind his 5.1% walk rate. The K-rate (17%) is a legitimate ceiling concern, but the command profile keeps the line clean start after start. SP3 or better in 12-team leagues.
