Shane Bieber delivered a commanding return to Major League Baseball on Friday, striking out nine over six innings of two-hit, one-run ball to help the Toronto Blue Jays defeat the Miami Marlins 5–2 at LoanDepot Park. The outing was the 2020 AL Cy Young Award winner’s first big-league appearance since April 2, 2024, following Tommy John surgery and nearly 16 months of rehabilitation. Bieber needed 87 pitches to retire 18 of the 21 batters he faced, including 12 straight after surrendering a second-inning solo homer to Javier Sanoja. He issued no walks and left with Toronto leading 5-1. Offensively, Daulton Varsho powered the Blue Jays with a two-run homer and an RBI double, while Ty France contributed a two-run single in the first inning. Marlins starter Ryan Gusto, making his home debut, was tagged for five runs on seven hits in five-plus innings. Toronto acquired Bieber from the Cleveland Guardians at the July 31 trade deadline to bolster a rotation aiming for a deep postseason run. Friday’s win lifted the AL East leaders to 75-54. José Berríos is scheduled to face Miami’s Janson Junk in the second game of the three-game series on Saturday.
