CHICAGO -- The Chicago White Sox placed Luis Robert Jr. on the 10-day injured list on Wednesday, a tough blow for the center fielder after he started to deliver at the plate.
Robert has a left hamstring strain. He left Tuesday night's 5-4 loss to Kansas City because of hamstring soreness.
The White Sox also recalled outfielder Will Robertson from Triple-A Charlotte before their series finale against the Royals.
The 28-year-old Robert got off to a tough start this year, batting .190 with nine homers, 35 RBIs and 93 strikeouts in his first 79 games.
