Logan Gilbert’s Injury Means Another Patch for the Mariners Rotation

Particularly in light of their failure to upgrade their roster this winter, starting pitching is the foundation of the Seattle Mariners. Last year, four of their starters took at least 30 turns, and the unit posted the majors’ lowest ERA (3.38) while ranking either first or second in the American League in FIP and WAR as well. But while this year’s Mariners are currently running first in the AL West at 17-12, their rotation has scuffled, in part because it’s far from whole. George Kirby, who led the staff in WAR last year, began the season on the injured list due to shoulder inflammation, and now Logan Gilbert, who made the All-Star team and received Cy Young votes, has joined him there due to a flexor strain.
The 27-year-old Gilbert made his sixth start of the season on Friday night at T-Mobile Park against the Marlins. While the results were impressive — he needed just 29 pitches to throw three perfect innings, striking out three — his average four-seam fastball velocity was down 1.1 mph from his season average of 95.6, and his slider and curve were a bit slower than usual as well. He did not return for the fourth inning, replaced by reliever Casey Lawrence, and the Mariners soon announced that he had departed due to forearm tightness.
