Early Life and Background
Jonathan Patrick Cannon was born on July 19, 2000, in the United States. He grew up in Roswell, Georgia, a suburb northwest of Atlanta that has produced several notable baseball players. Cannon attended Centennial High School in Roswell, where he played both sides of the ball as a two-way player before focusing on pitching.
During his senior season at Centennial in 2019, Cannon posted a 4–1 record on the mound with a 0.51 earned run average (ERA) and also batted .368 with two home runs. Despite his strong high-school résumé, he went unselected in the 2019 Major League Baseball draft and chose to honor his commitment to the University of Georgia.
Path to Professional Baseball
Cannon joined the University of Georgia Bulldogs baseball program, where he spent three seasons developing his pitching arsenal. In his freshman year of 2020, he appeared in limited action, pitching 11 and one-third innings, striking out 12, walking two, and allowing no earned runs before the season was cancelled due to the COVID-19 pandemic. That summer he played for the Gainesville Braves of the Sunbelt Baseball League, a team coached by former big-leaguer Micah Owings.
He missed the start of the 2021 season while recovering from mononucleosis but returned to post a 4–2 record with a 3.98 ERA and 57 strikeouts in 63 and one-third innings over 13 appearances, including 12 starts. Although he was considered a top prospect for the 2021 MLB draft, he again went unselected. After the 2021 college season, he played collegiate summer baseball with the Orleans Firebirds of the Cape Cod Baseball League.
As a junior in 2022, Cannon was named Georgia’s Opening Day starter. He missed time with a forearm injury but still went 9–4 with a 4.02 ERA over 78 and one-third innings in 13 starts. Following the 2022 season, the Chicago White Sox selected him in the third round, with the 101st overall pick, of the 2022 Major League Baseball draft, and he signed for $925,000.
