Mariners fans weren't happy in 2001 when star shortstop Alex Rodriguez bolted to the rival Texas Rangers in free agency, signing a 10-year, $252 million deal that was the largest in baseball history at the time. So when A-Rod returned for the first time, two weeks into his first season in Texas, he was greeted with thunderous boos ... and a stadium filled with fans throwing fake money at their former favorite. One fan dangled a dollar bill off a fishing pole over Rodriguez' head as he stood in the on-deck circle, and the swirling winds carried fake bills printed with A-Rod's face all around the stadium.

In 1995, there were rumors the Mariners might relocate to the Tampa area.

Seattle set a Major League Baseball (MLB) record by using 42 pitchers in 2019, breaking the previous mark of 40 pitchers used by the Mariners in 2017 and the Texas Rangers in 2014. The Mariners used a total of 67 players in 2019, also a record.
