ROUND ROCK, Texas — Three Omaha pitchers combined to allow one run Sunday night, and the Storm Chasers seized control with a three-run fourth inning on the way to a 5-1 victory over the Round Rock Express.
After Jake Kalish pitched the first three innings in his Triple-A debut for Omaha, allowing one run on five hits, Mark Peterson came on for the next three innings. Peterson (3-3) earned the win, allowing no hits and striking out three. Seth Maness pitched the last three innings for his second save.
Brayan Pena and Ramon Torres hit back-to-back run-scoring singles in the fourth inning to put the Chasers up 3-1, then Jorge Soler put Round Rock away with a two-run homer in the ninth inning.
