Cardinals' Zack Thompson: Taking Gray's rotation spot

Cardinals manager Oliver Marmol announced Friday that Thompson will be a member of the club's season-opening rotation, Lynn Worthy of the St. Louis Post-Dispatch reports.

Veteran Sonny Gray (hamstring) will begin the season on the injured list, opening the door for Thompson to earn a rotation spot. The southpaw pitched well during spring training with a 2.81 ERA and 14:6 K:BB across 16 innings, but Thompson will likely only get a few starts to stake his claim to a more permanent rotation spot since Gray isn't expected to have a lengthy absence.
