Twins' Joe Mauer to reportedly announce retirement after 15 seasons

Joe Mauer, the 2009 American League MVP who has spent all 15 seasons of his major league career with the Minnesota Twins, reportedly will announce his retirement Sunday.

The Minneapolis Star-Tribune reported that Mauer has bought a full-page advertisement for Sunday's editions that informs fans of his decision.

"Thank you, Minnesota Twins, and thank you, fans, for making my career as special and memorable as it was. Because of you I can leave the game I love with a full and grateful heart."

The three-time American League batting champion -- the only catcher to ever win three batting titles -- would have been a free agent after his eight-year, $184 million contract expired at the end of the 2018 season.

In addition to the concussion suffered this past season, Mauer also suffered one in 2013, which facilitated his move from catcher to first base.

Mauer, 35, had stated that he had no interest in playing outside of his home state.

The six-time All-Star selection will finish his career with a .306 batting average with 143 home runs and 923 RBIs. Mauer is the Twins' all-time leader in times on base, passing Hall of Fame member Harmon Killebrew.

Mauer, who was selected by the Twins with the first overall selection in the 2001 draft, also won three Gold Glove awards and five Silver Sluggers during his career.
