Hard-throwing St. Louis Cardinals reliever Jordan Hicks has opted out of playing this season, citing pre-existing health concerns.

The 23-year-old Hicks was diagnosed in high school as having Type 1 diabetes.

Hicks, who routinely tops 100 mph, is recovering from Tommy John surgery on June 26, 2019. The right-hander’s availability for this season was uncertain.

Hicks had been taking part in workouts at Busch Stadium, leading up to the Cardinals’ opener on July 24 at home against Pittsburgh.

Dodgers pitcher David Price, Giants catcher Buster Posey and Washington infielder Ryan Zimmerman are among about a dozen players who have opted out this year.

Hicks was 2-2 with 14 saves and a 3.14 ERA last season before he injured his elbow. He has hit 105 mph with his fastball.

Hicks was due $214,370 as a prorated share of his $578,800 salary. He gets paid if the pre-existing health concern has been determined to make him a high-risk individual.

Ryan Helsley and Giovanny Gallegos are expected to handle the late innings out of the Cardinals’ bullpen.

Carlos Martinez led St. Louis with 24 saves last season, posting his first save on June 1. The Cardinals had been working in spring training in February to move Martinez to the rotation, where he was a two-time All-Star.
