On May 8, 2018 — James Paxton of the Mariners becomes only the second-ever Canadian-born pitcher to throw a no-hitter, after Dick Fowler in 1945, turning the trick against the Blue Jays in a 5 – 0 win. The three no-hitters pitched so far this season have been accomplished in three different countries: the United States, Mexico and Canada, and no Canadian pitcher had ever pitched one on Canadian soil before Paxton. In what is overall an awful day for the Blue Jays, closer Roberto Osuna is arrested in the early hours of the morning on charges of assault against a woman and is immediately placed on administrative leave by Major League Baseball.
