Kirby attended Elon University, where he refined his craft and caught the attention of professional scouts with his remarkable strike-throwing ability and mature approach on the mound. The Seattle Mariners selected Kirby in the first round (20th overall) of the 2019 MLB Draft, recognizing his advanced pitching acumen despite his relatively modest velocity. He progressed rapidly through the minor league system, making his major league debut on May 8, 2022, against the Tampa Bay Rays. His rookie season established him as one of baseball's most promising young starters, posting impressive numbers while demonstrating the exceptional control that had defined his amateur career. Kirby continued to develop into a reliable rotation anchor, becoming known for his ability to consistently throw strikes and work efficiently through opposing lineups.

Within the modern game's emphasis on strikeouts and velocity, Kirby represents a throwback approach that prioritizes location and command over raw power. His success demonstrates that exceptional control remains a valuable commodity in professional baseball. For the Seattle Mariners, he has emerged as a cornerstone of their pitching staff and a model of consistency. His methodical approach and strike-zone mastery continue to influence how scouts and organizations evaluate pitching prospects, proving that command can be just as valuable as overpowering stuff.
