Cardinals' Miles Mikolas to have season-ending arm surgery

St. Louis Cardinals starting pitcher Miles Mikolas will have season-ending surgery on the flexor tendon in his right arm.

What It Means:

Mikolas apparently reaggravated his flexor tendon while preparing for the rescheduled season after initially injuring it in the spring. The Cardinals plan on the right-hander being ready for the 2021 season. Mikolas will turn 32 in August. Daniel Ponce de Leon will replace Mikolas in the Cardinals' rotation and start Wednesday versus the Minnesota Twins.

Mikolas spun a 4.16 ERA and 1.22 WHIP with 144 strikeouts over 184 innings in 2019.
