Seattle Mariners sources said the recall of George Kirby, the star promotional detective

Seattle Mariners call the right-hander George Kirbyone of the best potential players in baseball, sources told ESPN’s Jeff Bassan on Saturday.

Sources have told ESPN that Kirby, who has been scratched since making his Double-A Arkansas debut on Saturday, will play his first major league game for the Mariners against the Tampa Bay Rays on Sunday.

The Mariners picked the right junior rookie on Thursday Matt Brash at Triple-A Tacoma, with a plan to move him into the Bullpen role for the remainder of the season.

Kirby, 24, who was Elon’s 20th pick in the 2018 MLB Draft, has a massive ceiling with great driving and above-average stuff, including Fastball, who averaged 97.3 mph during the 2021 season.
