Zack Greinke

The Houston Astros bolstered a fantastic pitching staff by acquiring Zack Greinke, a crafty right-hander who has dominated MLB for more than a decade. Greinke joins Justin Verlander and Gerrit Cole as three of the top five pitchers in all of Baseball at limiting baserunners, as all three aces have a WHIP of 1.00 or lower.
