Stephen Kolek improved to 4-1 in Sunday’s 4-0 victory over the Astros, twirling 7 1/3 scoreless innings while striking out four and allowing just five hits.
Kolek walked one and lowered his ERA to 2.68 through eight starts. He has been even better over his past six with a 1.59 ERA since May 17. Kolek’s strikeout rate doesn’t pop, but he generates grounders and limits walks, a formula that can work for longer than ERA estimators indicate. It’s been a very valuable stretch in deeper fantasy leagues where quality pitching is scarce, but managers shouldn’t expect these results every time out. Kolek has another test in his next start against the Cardinals.
