Jackson Kowar continued his rookie year struggles, giving up five runs in four innings in a 7-1 loss to the Mariners. The Royals lose the series to Seattle and drop four of six on the homestand.
The problems started in the first for Kowar, when he walked back-to-back hitters to load the bases. Rookie Jarred Kelenic doubled to score two and make it 2-0 Seattle. Kowar would walk Dylan Moore to lead off the third. The oft-heard Denny Matthews adage that “leadoff walks will kill you” proved to be correct after J.P. Crawford singled Moore to third, and Ty France drove him home to make it 3-0 Mariners.
