Dodgers' Tyler Glasnow returns to the injured list, this time due to elbow tendonitis

For the second time in just over five weeks, Los Angeles Dodgers pitcher Tyler Glasnow is on the injured list.

Glasnow, 30, was placed on the 15-day IL before Friday's game because of elbow tendonitis. He was placed on the IL on July 9 because of back pain. He was activated again on July 24 and started four games before being injured again.

In 22 starts this season, Glasnow has 168 strikeouts in 134 innings (a career high) with a 3.49 ERA and a 9–6 record.

Justin Wrobleski was recalled from Triple-A Oklahoma City to take Glasnow's place on the roster and started Friday's game against the St. Louis Cardinals. In his previous stint with the Dodgers this season, the left-hander started four times and posted a 4.04 ERA and 15 strikeouts in 20 innings. Wrobleski was sent back to the minor leagues when the Dodgers signed Jack Flaherty at the trade deadline.

Glasnow was scheduled to start on Saturday after being moved back in the rotation by one day. Bobby Miller is now expected start in Glasnow's place. Miller was already in the team about the Dodgers taxi squadbut hasn't pitched since July 9. In seven starts, he has an ERA of 8.07 with 27 strikeouts in 29 innings.

The good news is that Dodgers manager Dave Roberts told reporters after the game on Friday that an MRI scan of Glasnow's elbow showed structural damage and that he expected the right-hander to be cleared to play in 15 days. Still, it's more bad news for the Dodgers pitchers, who have been weakened by injuries this season.

Earlier this week, rookie River Ryan suffered a season-ending injury that requires Tommy John surgery. He joins Tony Gonsolin and Emmet Sheehan, who both had season-ending surgery, while Dustin May has a torn esophagus.

Walker Buehler was activated from the injured list on Wednesday. He struggled in his return, allowing four runs in 3 1/3 innings. Yoshinobu Yamamoto appears to have recovered from a rotator cuff strain and threw a simulated game on Friday.

Elsewhere on the roster, Ryan Brasier and Connor Brogdon will soon begin minor league rehab duties, Brusdar Graterol is recovering from a hamstring strain and Blake Treinen is dealing with left hip discomfort.

The Dodgers are currently locked in a tight battle in the NL West, holding a two-game lead over the San Diego Padres and Arizona Diamondbacks. (Los Angeles had an 8 1/2-game lead on July 23.)
