The 37-year-old southpaw appeared in a total of 258 games (129 starts) during his 13-year big league career -- taking the field for the Padres, Marlins, Astros, Angels, Yankees, Mariners, Pirates, Orioles and Cardinals. Overall, he went 46-49 with a 4.54 ERA, 1.35 WHIP and 6.5 K/9 while also recording three saves. 

LeBlanc is headed for surgery after suffering a setback with his injured left elbow late last month. The exact nature of the procedure is unknown, but he is expected to be ready for the beginning of the 2022 season. The veteran southpaw will be a free agent this winter.

LeBlanc got through a bullpen session Tuesday with no issues but didn't bounce back well the next day. It's not clear what the next step is for LeBlanc, but Cardinals manager Mike Shildt indicated Thursday that the lefty's season could be over. "The calendar is the calendar," Shildt said. "And the recovery period is of a little concern, as well.”

While there's no structural damage for LeBlanc, elbow injuries rarely require just a minimum stint on the shelf, and LeBlanc is not an exception. The southpaw was placed on the injured list on Friday, and likely won't be back until closer to the end of August or beginning of September.
