The Boston Red Sox have placed Chris Young on the disabled list and have recalled OF Bryce Brentz from Triple-A Pawtucket.
Brentz will be available for Friday night's game at Texas.
Young left Thursday's 8-7 win over the Chicago White Sox with a strained right hamstring.
He was injured in the second inning after leading off with a single off the top of the Green Monster. He aggressively rounded first, stopped, reached for his right leg above the knee, limped back to the base and crumpled to the ground.
