MESA, Ariz. – Cubs pitcher Matt Garza, facing batters for the first time since July, endured a frustrating day.

Garza was pulled from his first live batting practice session Sunday at Fitch Park after suffering a mild lat strain. Garza was only halfway through his scheduled 40 pitches when he felt a muscle grab on his left side. He threw one more pitch before walking off the field.

“I was fine throwing, but I felt something,” Garza said. “I’m not going to push it if I don’t have to. We’ll see [today] and go from there.”
