Mauer, 30, is hitting .320 with eight homers, 24 doubles and 26 RBIs in 74 games. He also leads Major League catchers with a .404 on-base percentage and 49 runs scored.
Mauer was an All-Star last year for the fifth time in his career and was the Twins' lone representative in the Midsummer Classic. He was voted in as a starter from 2008-10 and was the leading vote-getter in the Majors in '10.
"It's a tremendous honor," Mauer said. "As long as they keep having me, I'd love to come back. It's a great event and hopefully I'll be able to do it again."
If elected, the 2009 American League MVP would join Ivan Rodriguez (12 times) and Hall of Famer Carlton Fisk (seven) as the only AL catchers to earn four fan-elected starts. In addition, he would become one of three players in Twins history to accomplish the feat, joining Hall of Famers Rod Carew (nine times) and Kirby Puckett (six).
