From BA:
In the summer of 2017, one inning into his professional career after being taken out of Florida Gulf Coast as a 16th-round pick, Kutter Crawford experienced elbow discomfort.
It was enough to shut the righthander down for the duration of his first pro summer, but not enough for surgery.
But he was pitching through discomfort that steadily grew and ultimately forced him to have Tommy John surgery after the 2019 season.
During rehab, he had more discomfort and had a second surgery to remove bone spurs in his elbow which pushed his rehab out further.
