Félix Hernández's Perfect Game
Félix Hernández threw a perfect game for the Seattle Mariners against the Tampa Bay Rays on August 15, 2012, winning 1–0.
Seattle Mariners
The 2001 Mariners won 116 games, which no club has beaten in a full season, and lost the Championship Series to the Yankees. They have never reached a World Series, alone among the thirty current franchises, and have won four division titles in 49 seasons at 3,689-4,022.
That 2001 season is the best on file by a distance; the worst is 1978, at 56-104, in the club's second year. Home was the Kingdome, a concrete dome with a roof that shed tiles, and Safeco Field from 1999, now T-Mobile Park.
Eight Hall of Famers have played here, among them Ken Griffey Jr., who was drafted first overall by the club at seventeen, Randy Johnson, Edgar Martínez and Ichiro Suzuki, who arrived in 2001 as a 27-year-old rookie and led the league in hits. Lou Piniella managed for ten seasons and won 836 games, including the 116-win year.
