Nathan, who has a 2.06 ERA in seven seasons with Minnesota, has been an efficient closer over the years, as his 88.9 save percentage (255-for-287) ranks second behind Yankees closer Mariano Rivera (89.2) among active players with at least 190 opportunities.
The Twins are also the only organization with a pair of relievers with 250 career saves, as only 30 pitchers in baseball history have reached that plateau.
"For me, it's just an honor to be mentioned with a guy like Rick Aguilera," Nathan said. "I got a chance to meet him. He's such a great guy and had such a great career. He's a Twins Hall of Famer. So to be around this team for that long and to have the opportunity to close over here when I had one career save with the Giants says a lot about the [Twins]. So for them to stick with me for this long is definitely an honor and a big deal for me."
Nathan has also pitched well of late, as he has a 1.46 ERA in 13 games since being activated from the disabled list on June 24, after he experienced a setback with his forearm related to last year's Tommy John surgery that kept him out of action for the 2010 season.
