Matt Garza has a strain on the left side of his body "where the lat meets the oblique" and is expected to miss about a week.

"It's a mild strain, we're probably going to let him rest for about a week," Jed Hoyer said. "Make sure he can ramp back up his throwing."

Garza was hurt as he threw to hitters on Sunday during batting practice and had an MRI on Monday. The injury will delay his first Cactus League start.
