Oakland knows how to find diamonds in the rough, so this could be yet another example. De La Rosa is still only 24 years old and totals 44 big-league appearances out of the bullpen, so he may be primed for a breakthrough with the A's. This is a nice pickup.

The D'backs had designated De La Rosa for assignment, so clearly he was no longer in their long-range plans. As a result, they moved him to Oakland and received some cash for their troubles. It's always good when you receive something for nothing in pro sports.

De La Rosa could be a fantasy sleeper reliever in 2015, so he should be on the radar moving forward. Oakland is notorious for moving players in and out of the organization, so he might get a chance to pitch in the late innings at some point.
