Rowdy reached the majors with the Blue Jays as part of their September call-ups in 2018. In his debut on September 5th, he doubled as a pinch-hitter off Jacob Faria of the Tampa Bay Rays. He had spent the season in AAA with the Buffalo Bisons where he hit .270 with 13 homers and 50 RBIs in 112 games as the starting first baseman. He also hit doubles in his first two plate appearances in his second game, against the Cleveland Indians on September 6th, to set a record and finished that day at 3 for 4, the other hit being yet another double. Not done yet, he went 2 for 5 the next day, with both hits also being of the two-base variety. That gave him 6 doubles in his first 10 career plate appearances. He continued to do well over the next few weeks, and on September 21st, he had a homer and double in a spectacular 9-8 win over the Tampa Bay Rays. His double in the 9th drove in the first run of a spectacular 7-run comeback in the 9th inning in that game, and at the end of that day, he was hitting .385 with 8 doubles and 2 homers in 14 games. He finished his first cup of coffee at .314 in 23 games, with 9 doubles and 4 homers for a slugging percentage of .614.
In 2019, he made the team out of spring training, making him one of a number of rookies occupying spots in the regular line-up, alongside OF Billy McKinney, C Danny Jansen and 3B Vladimir Guerrero Jr. who joined them a month later. He was mainly used as the DH, while occasionally spelling Justin Smoak at 1B. He was benched against most lefties at the start of the season, but was given more opportunities to face them as things progressed, especially after he hit his first career grand slam off lefty Tony Watson of the San Francisco Giants on April 23rd. He had a great game against the Boston Red Sox on May 21st when he victimized another southpaw, Eduardo Rodriguez, for a pair of homers and drove in 5 runs in a 10-3 win.
