Spencer Miles — Miles to the Majors
A professional baseball career rarely follows a straight line. For Spencer Miles, the road from the University of Missouri to the Toronto Blue Jays included injury setbacks, long stretches away from competition, and an opportunity that changed the direction of his career.
His journey is a story of returning to the mound—and being ready when another organization saw a chance worth taking.
A Missouri Foundation
Miles pitched at the University of Missouri from 2020 through 2022. Across three seasons, the right-hander appeared in 33 games, including 25 starts, and recorded 122 strikeouts in 145 innings.
In the 2022 MLB Draft, the San Francisco Giants selected him in the fourth round with the 136th overall pick. College baseball had led to a professional opportunity, but the years ahead would test his ability to get back on the field.
A Career Interrupted
A back injury cost Miles the 2023 season. His return in 2024 was brief: after pitching just 7⅓ innings in the Arizona Complex League, he underwent Tommy John surgery in June.
He did not pitch during the 2025 minor-league regular season. Instead of building a conventional résumé of innings and promotions, Miles faced another extended period of rehabilitation.
His next opportunity to compete came in the Arizona Fall League.
Making an Impression in Arizona
Pitching for the Scottsdale Scorpions after the 2025 regular season, Miles made five appearances, including four starts. He struck out 12 batters in 8⅔ innings and reached 98.4 mph.
The workload was small, but it gave evaluators a fresh look at a pitcher whose professional experience had been limited by injury.
On December 10, 2025, the Blue Jays selected Miles from the Giants in the Rule 5 Draft. Toronto had given him a new route toward the majors.
From Rule 5 Pick to Major Leaguer
Miles earned a place on Toronto’s Opening Day roster despite having only 14⅔ innings of regular-season minor-league experience. On March 28, 2026, he made his major-league debut against the Athletics, working a scoreless 11th inning.
His role soon grew beyond that first appearance. By May, MLB coverage was examining his potential as a starting pitcher, following a beginning to the season that had already made him one of Toronto’s most unexpected stories.
By July, he had taken on responsibilities ranging from bulk innings to traditional starts. The player who had spent so much time unable to compete was now helping a major-league club navigate the demands of a full season.
A Journey Worth Following
At JL Glove Co., our player stories celebrate the people and paths that make baseball compelling. Miles’ career offers a particularly clear example of why a player’s progress cannot always be measured by an uninterrupted climb through the minor leagues.
His route included college starts, a draft selection, rehabilitation, a short fall-league opportunity, and a new organization willing to take a chance.
For young players, his story is a reminder that a setback does not have to be the final chapter. Sometimes the next opportunity arrives on a different timeline—and through a different door—than expected.
