In an afternoon game at Kauffman Stadium, the Seattle Mariners defeated the Kansas City Royals 4-2, thereby also locking up the series two games to one. Seattle upped their record to 6-4, and Kansas City fell to 3-7.
Going into this season, Danny Duffy was clearly the most important and best pitcher for the Kansas City Royals. Expectations were high; from 2016-2017, Duffy started 50 games and put up a nice 3.68 ERA and 3.74 FIP over those 308 innings. If the 2018 Royals were to succeed, they needed Duffy to be his best.
