King Felix's perfect game is the first in franchise history. Randy Johnson fired the team’s first no-no on June 2, 1990 against the Detroit Tigers, per Baseball Almanac. That game was at the Kingdome.
Equally impressive is that this is the second no-hitter for the Mariners this season. Kevin Millwood combined with five other pitchers to throw a no-hitter on June 8th against the LA Dodgers.
With a complete game, 12-strikeout gem, the 26-year-old Venezuela native improves to 11-5 with a 2.60 ERA and 1.04 WHIP this season.
Jeremy Hellickson, who pitched impressive as well, took the loss for the Rays.
