Iwakuma blanked the Orioles for his first career complete game on Wednesday, joining Hideo Nomo as the only Japanese pitchers to hurl a no-hitter.
Iwakuma's no-hitter is the fourth in the Majors this season, but the first in the AL since Hernandez threw a perfect game on Aug. 15, 2012, against the Rays. There have been three National League no-hitters this season: Philadelphia's Cole Hamels vs. the Cubs on July 25, Washington's Max Scherzer vs. the Pirates on June 20 and San Francisco's Chris Heston vs. the Mets on June 9.
Seattle has thrown the past three no-hitters in the AL, with a combined gem on June 8, 2012, and Hernandez's perfect game two months later.
