Greinke (16-5) struck out seven and picked up the win Saturday, allowing one run on six hits over six innings in a 6-1 victory over the Royals.
It was the right-hander's first ever win over Kansas City, the team he began his career with back in 2004. Greinke is 6-1 with a 3.10 ERA and 39:8 K:BB through 49.1 innings in eight starts since joining the Astros, and he'll look to stay in the win column in his next outing Friday, at home against the Angels.
