Nathan Alexander Pearson, born on August 20, 1996, is an American professional baseball pitcher for the Toronto Blue Jays of Major League Baseball (MLB).
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.
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.
On July 29, 2020, Pearson made his MLB debut against Max Scherzer and the Washington Nationals. The game was played in Washington despite being a home game for the Blue Jays, as the COVID-19 pandemic had forced the Blue Jays into Sahlen Field in Buffalo, which was not ready for use.
He went five innings, giving up two hits and two walks with five strikeouts, and surrendered no runs in his debut, though the Nationals won 4–0. With the 2020 Toronto Blue Jays, Pearson appeared in 5 games, compiling a 1–0 record with 6.00 ERA and 16 strikeouts in 18 innings pitched.
