• Cubs pitcher Jake Arrieta may have made his last Minor League rehab start.

On Saturday, Arrieta threw 44 pitches over two innings for Double-A Tennessee in his fifth Minor League outing. This was the equivalent of a starting pitcher's last Spring Training start, and was intended to be shorter.

The right-hander, who was slowed this spring because of tightness in his shoulder, gave up two runs (one earned) on two hits and one walk over two innings and struck out two.

As of now, Carlos Villanueva is scheduled to start Wednesday for the Cubs against the Reds. The Cubs want to see how Arrieta feels after Saturday's outing before deciding whether he's ready to join the big league team or needs more rehab time.
