• Cubs pitcher Jake Arrieta will make another Minor League rehab outing on Saturday with Double-A Tennessee, which could be the right-hander's final tune-up before he's activated from the disabled list.

Arrieta was slowed this spring by tightness in his right shoulder, and he has made four rehab outings, including 5 2/3 innings on Monday for Class A Advanced Daytona.

"He's been progressing well," Cubs manager Rick Renteria said.
