Aumont announced in June that he would retire from professional baseball, CBC News reports.
Aumont attended spring training with the Blue Jays after agreeing to a minor-league deal over the winter, but he wasn't added to the 60-man roster pool for summer camp after electing to step away from baseball and take up farming as his next career. A first-round pick of the Phillies in 2007, the 31-year-old Aumont appeared in 46 career MLB games, logging a 6.80 ERA in 43.2 innings.
