Seattle Mariners pitcher Hisashi Iwakuma tossed a no-hitter this afternoon against the Baltimore Orioles.
Iwakuma's no-no is the fourth during the 2015 season. The three previous no-hitters came from San Francisco Giants rookie Chris Heston, Washington Nationals ace Max Scherzer and Cole Hamels in his final appearance with the Philadelphia Phillies (he has since been traded to the Texas Rangers).
Iwakuma became the first AL pitcher to throw a no-hitter since his teammate Felix Hernandez threw a perfect game against the Tampa Bay Rays in August 2012. He is also the first Japanese pitcher to throw a no-hitter since Hideo Nomo did so in his debut with the Boston Red Sox in 2002. Curiously it was also against the Orioles. Nomo also threw a no-hitter with the Los Angeles Dodgers against the Colorado Rockies in 1996.
