Randy Johnson’s ball from his first no-hitter at the Hall of Fame.
Randy Johnson threw the Mariners’ first no-hitter in 1990, and Chris Bosio added one in 1993. The Mariners threw a combined no-no in 2012, beginning with six innings from Kevin Millwood and short relief stints by Charlie Furbush, Stephen Pryor, Lucas Luetge, Brandon League and Tom Wilhelmsen.
Felix Hernandez threw a perfect game for the M’s later during the 2012 season, and Hisashi Iwakuma (2015) and James Paxton (2018) added the fifth and sixth no-nos.
