The Seattle Mariners on Saturday reportedly placed starting pitcher Felix Hernandez on the 10-day disabled list with right biceps tendinitis.

MLB.com's Greg Johns tweeted the news.

Hernandez's trip to the DL was retroactive to Wednesday, and Johns noted the team would call up left-hander Marco Gonzales, who made his season debut in June but has spent the bulk of his year in Triple-A.

This move marked another setback for Seattle's ace after he missed time earlier in the season with a shoulder injury.

Hernandez has been durable throughout his career, however, and he entered the 2017 campaign with 11 straight seasons of 25 or more starts (the first 10 of which featured 30 or more starts).

The six-time All-Star and 2010 American League Cy Young Award winner has a 4.28 ERA and 5.20 FIP in 2017, per Baseball-Reference.com. He's attempting to rediscover the form that made him one of baseball's best pitchers during his prime. From 2009 to 2014, Hernandez posted a 2.73 ERA and 1.10 WHIP with 1,358 strikeouts and 356 walks in 1,394.1 innings.

The Mariners will have to rely on other starters—such as James Paxton, Ariel Miranda and Erasmo Ramirez—while Hernandez is out. While it is unfair to expect any of them to replicate Hernandez's formerly fine form, they can at least help keep Seattle afloat in the postseason race until he is ready to return.
