Yankees closer Mariano Rivera has a chance to join an elite group in Seattle this week. Rivera enters New York's series against the Mariners with 599 career saves. Trevor Hoffman is currently the only member of the 600-save club. Hoffman finished his career with 601 saves, meaning Rivera could potentially tie or even surpass the all-time saves mark in Seattle. Rivera first rose to prominence as a 25-year-old rookie reliever in the 1995 American League Division Series against the Mariners. "The best ever. I keep saying the same thing over and over again, and it sounds repetitious every time I talk about Mo, but it's true," Rivera's longtime teammate, Jorge Posada, said. "There's nobody [who's] ever going to get close to what he's been able to achieve, because there's nobody better. It's just that simple."
