Pearson was considered one of the top prospects for the 2017 Major League Baseball draft. He was selected 28th overall by the Toronto Blue Jays, and signed on June 28 for a $2.45 million bonus. Pearson was assigned to the Rookie-level Gulf Coast League Blue Jays, and promoted to the Short Season-A Vancouver Canadians after making one start. Through his first six starts, Pearson did not allow a run, and yielded only four hits and one walk while striking out 16 in 13 total innings. He finished the 2017 regular season with a 0.90 ERA, 26 strikeouts, and a 0.60 WHIP in 20 innings pitched.

He went four innings against Spokane and struck out 10 batters in a 2–1 win.
Pearson was assigned to the Advanced-A Dunedin Blue Jays to begin the 2018 season, but opened the year on the disabled list with an oblique injury. He made his Florida State League debut on May 7, but left the game after being struck by a line drive in the second inning. The following day, the team announced Pearson had suffered a broken ulna in his right arm. He remained on the disabled list for the rest of the 2018 season, and played for the Surprise Saguaros of the Arizona Fall League during the offseason.
