Early Life and Background
Kaleb James Ort was born on February 5, 1992, in Lowell, Michigan. He grew up in the small West Michigan community and developed his baseball skills there before pursuing the sport at the collegiate level. His size and right-handed delivery became defining traits of his game from an early stage.
Ort attended Aquinas College in Grand Rapids, Michigan, where he played college baseball. Despite his time on the mound for the Saints, he went undrafted in the MLB Draft, meaning he had to find another route into professional baseball.
Path to Professional Baseball
After going undrafted, Ort signed with the Joliet Slammers of the independent Frontier League on October 7, 2015, beginning his professional career. In his first season with Joliet, he appeared in 20 games, started 12, and posted a 3–4 win–loss record with a 6.05 earned run average (ERA) and 61 strikeouts in 61 innings pitched.
On September 23, 2016, he signed a minor-league contract with the Arizona Diamondbacks. He was released in March 2017 without appearing in a game for the organization, returned briefly to Joliet, and then signed a minor-league deal with the New York Yankees on May 16, 2017. From that point, Ort progressed steadily through the Yankees’ developmental ranks.
