It appears Carlos Quentin was missing baseball too much to stay retired.
The deal includes an invite to spring training, according to MLB.com's Rhett Bollinger. Quentin will earn $750,000 if he makes the major-league roster, reports LaVelle E. Neal III of the Minnesota Star Tribune.
A source tells Mike Berardino of the St. Paul Pioneer Press that Quentin's contract includes a June 1 opt-out clause if he's not in the majors by that point.
Quentin, 33, did not appear in the big leagues last season and struggled at Triple-A Tacoma as a member of the Seattle Mariners organization, hitting .176/.263/.235 in 19 plate appearances before announcing he was hanging up his cleats.
"Over the past several days, it became clear to me that my injuries have taken too great of a physical toll for me to be able to perform at the level I expect from myself," he said in a statement last May. "As a result, I believe it is the right time for me to walk away and to refocus my energy on the next chapter of my life with my family."
The once-formidable power hitter has dealt with chronic injuries throughout his career, including problems with both of his knees.
Quentin, a former first-round draft pick of the Arizona Diamondbacks, owns a career hitting line of .252/.347/.484 with 154 home runs and 491 RBIs across nine big-league seasons.
His best year came with the Chicago White Sox in 2006, when he slashed .288/.394/.571 with 36 home runs and 100 RBIs.
