Dodgers place All-Star, NL strikeouts leader Tyler Glasnow on injured list with back tightness

The Los Angeles Dodgers placed All-Star pitcher Tyler Glasnow on the 15-day injured list with back tightness on Tuesday.

Manager Dave Roberts told reporters before Tuesday’s game against the Philadelphia Phillies that Glasnow’s back “tightened up on him on Sunday” while he played catch. The move to the injured list will be retroactive, and Roberts expects Glasnow to return shortly after the All-Star break.

“Don’t know when he’s gonna start after the break, but it shouldn’t be too much further after the second half,” Roberts said.

Glasnow, 30, was selected to his first career All-Star team on Sunday. He’ll miss next Tuesday’s All-Star game while resting his back.

The Dodgers called up pitcher Michael Petersen from Triple-A Oklahoma City in a corresponding move.

Glasnow’s on pace to shatter his career-high workload in his ninth MLB season. In 18 starts, Glasnow’s pitched 109 innings this season. His career-high tally for a full season is 120 innings in 21 starts last season for the Tampa Bay Rays.

Glasnow leads the NL with 143 strikeouts and boasts a 3.47 ERA and 0.927 WHIP. He’s also the NL leader in strikeouts per nine innings (11.8) and hits allowed per nine innings (5.9).

Glasnow had Tommy John surgery in 2021 and missed most of the 2022 season. He returned in 2023 full time for the most productive season of his career.

Glasnow joins the injured list as three-time Cy Young winner Clayton Kershaw works to make his season debut for the Dodgers after recovering from offseason shoulder surgery. Kershaw threw two innings of a simulated game on Sunday and is expected to make a rehab start in the coming days.
