Kacy Clemens is the son of Roger Clemens and the brother of Koby Clemens and Kody Clemens. He was originally a pitcher in high school, from where he was drafted in the 35th round of the 2013 amateur draft by the Houston Astros. He went on to attend the University of Texas, where an arm injury forced him to move to first base. It was as a first baseman that he was drafted a second time, this time by the Toronto Blue Jays in the 8th round of the 2017 amateur draft.
After signing with the Jays, he was assigned to the Vancouver Canadians of the Northwest League. His professional career got off to a solid start as he hit .274/.379/.413 in 62 games, with 4 homers and 45 RBIs. On March 17, 2018, the Blue Jays decided to have a bit of fun in an exhibition spring training game against the Canadian junior national team: they fielded six second-generation ballplayers in their starting line-up, including Clemens at first base as part of an all second-generation infield. All six players were considered solid prospects in their own right, so it was not just a stunt on the team's part. He split the season between the Lansing Lugnuts of the Midwest League and the Dunedin Blue Jays of the Florida State League, hitting a combined .231/.331/.376 in 122 games. He slugged over .600 in 27 games for Lansing, but found the going a bit tougher against the more experienced players in the FSL.
Just after midnight on January 1, 2019, he was involved in an incident in a nightclub in Houston, TX in which he and a close friend, fellow minor leaguer Connor Capel, were allegedly beaten up by a bouncer, with both suffering injuries, although Capel's were more serious. The pair filed charges for significant damages against the club, while the bouncer was arrested on criminal charges for assault and causing injury.
