The Seattle Mariners are calling up George Kirby, who is considered one of the best pitching prospects in baseball.

Kirby, a 24-year-old who was the 20th overall pick in the 2018 MLB draft out of Elon, has a huge ceiling with excellent command and above-average stuff, including his fastball, which averaged 97.3 mph over the 2021 season.

Some Mariners brass have even called him "robopitcher" because of his excellent control.

Kirby has dominated in his five starts in the Double-A Texas League this season, going 2-0 with a 1.82 ERA and 24 strikeouts in 24 2/3 innings for Arkansas.
