TORONTO -- Seattle Mariners star Julio Rodríguez left Saturday's game against the Toronto Blue Jays in the sixth inning because of a sore lower back.
He was replaced in center field by AJ Pollock.
The 22-year-old Rodríguez won the AL Rookie of the Year award last season and was selected for the All-Star Game.
He began the day batting .236 with five homers, 13 RBIs and a .745 OPS this year.
