Swanson heading to IL with left side discomfort

10:43 PM UTC

CHICAGO – removed his helmet and immediately threw it to the dirt at his feet as he exited the batter’s box in clear discomfort on Sunday afternoon. Moments later, the Cubs shortstop exited Sunday's 11-4 loss to the Cardinals.

It was a concerning scene at Wrigley Field, where Swanson swung and missed at a first-pitch fastball from St. Louis’ Hunter Dobbins to begin the home half of the third inning. Following that whiff, Swanson grimaced in pain and was forced to leave the contest.

The Cubs announced that Swanson exited with “left side discomfort.” Postgame, manager Craig Counsell said Swanson will be placed on the injured list Monday. He's set to get an MRI to gather more information.

After Swanson’s departure on Sunday, Triantos took over hitting and drew a walk.

Moving forward, Nico Hoerner, a two-time Gold Glover at second base, will take over at shortstop with Pedro Ramírez in line for more starts at second base.

Through 119 games this season, the 32-year-old Swanson has hit .216/.300/.404 with 18 home runs, 16 doubles, 66 RBIs and 17 stolen bases for the North Siders. He ranked eighth overall among qualified defenders in fielding run value (12) and fifth in outs above average (16) entering Sunday’s game, per Statcast.
