Chicago White Sox pitcher Lucas Giolito is headed to 10-day IL with an abdominal injury, manager Tony La Russa said Saturday.
Giolito is expected to miss his next two starts, according to La Russa, after leaving his season-opening start on Friday because of abdominal tightness on his left side.
Giolito struck out six while pitching four innings of one-hit ball in Detroit.
"I'm concerned because he felt something," La Russa said after the game.
Giolito departed with a 3-0 lead, but the Tigers rallied for a wild 5-4 win.
The White Sox have been hit hard by injuries.
