George Kirby is officially back. The Mariners activated the 2023 All-Star from the injured list on Thursday morning to make his season debut against the Astros at Daikin Field in a four-game series opener later that night.

The timing couldn't be better, what with the Mariners' lead over the Astros being the size it is and with Houston heading to Seattle this week. Plus, two other starters - righties Logan Gilbert and Bryce Miller - remain out of commission for likely another couple weeks dealing with their own injuries, as well.

Seattle workhorse right-hander George Kirby is expected to start and make his season debut on Thursday night when the Mariners open a four-game series in Houston. Kirby has been on the injured list since March 24 with inflammation in his throwing shoulder.
