Schumaker, 33, played for the Dodgers last season and batted .263 with two home runs, 30 RBIs and a .332 on-base percentage in 125 games.
From 2005-12, Schumaker was a member of the Cardinals and batted .288 with a .342 on-base percentage over eight seasons. He was selected in the fifth round of the 2001 First-Year Player Draft by Walt Jocketty, who is now the Reds' general manager.
A left-handed hitter, Schumaker is a career .300 hitter with a .357 on-base percentage against right-handed pitching and a .211 hitter with a .280 OBP vs. lefties.
Although not known for defense, Schumaker is versatile and could give the Reds' bench a boost, playing second base and all three outfield positions. He also pitched in two games last season for the Dodgers.
