The deal, announced Tuesday, would give Quentin a $750,000 salary if he is added to the 40-man roster. He will report to big league spring training.
Quentin announced his retirement last May through the Seattle Mariners, citing chronic knee injuries. He played briefly for their Triple-A club, Tacoma.
Quentin was released by the Atlanta Braves last April after a trade with San Diego, the last team he played for in the majors in 2014. The two-time All-Star batted .252 over nine seasons with the Padres, Chicago White Sox and Arizona Diamondbacks.
Quentin hit 36 homers with 100 RBIs for the White Sox in 2008, but he hasn't topped 86 games since 2011.
