Elias said he felt some discomfort after throwing a changeup, but didn't call McClendon to the mound. Instead, the manager and trainer saw something of concern and his night was done. Now the final two starts of Elias' season are in jeopardy, with McClendon saying Wednesday he's "most likely" finished.
Elias is 10-12 with a 3.85 ERA in 29 starts and his 163 2/3 innings are the third-most of any rookie in the Majors behind the 165 of Kansas City's Yordano Ventura and Tampa Bay's Jake Odorizzi. Elias is 3-4 with a 2.31 ERA in 10 starts since the All-Star break, but the Mariners had been carefully monitoring his workload and giving him extra rest whenever possible.
"He's had a heckuva year," McClendon said. "He's had a tremendous second half. He's done a wonderful job and it hasn't gone unnoticed. He's everything we thought he was going to be."
Elias' turn in the rotation comes up on Sunday.
The Mariners announced after Wednesday night's 5-0 loss to the Angels that top prospect Taijuan Walker will now start Friday, which allows Chris Young and Hisashi Iwakuma to be pushed back a day to Saturday and Sunday, respectively.
