Mariners reinstate RHP Logan Gilbert (elbow) from IL

The Seattle Mariners reinstated right-handed starter Logan Gilbert from the 15-day injured list to start against the visiting Boston Red Sox on Monday.
Gilbert, 28, last pitched on April 25 and exited after three innings and 29 pitches due to forearm tightness. He was later diagnosed with a right elbow flexor strain.
The 2024 All-Star selection is in his fifth season with Seattle and has gone 42-31 with a 3.55 ERA for his career. That includes a 1-1 record and a career-best 2.37 ERA through six starts this season.
Gilbert led the major leagues in starts (33), innings pitched (208 2/3) and WHIP (0.887) in 2024.
In a corresponding move, the Mariners optioned right-hander Jackson Kowar to Triple-A Tacoma. Kowar, 28, made seven relief appearances and went 1-0 with a 2.08 ERA in 8 2/3 innings.
