Aquino is just 22 years old and has already reached Double-A ball, which bodes pretty well for his future within the Blue Jays organization. That said, he needs to improve his control in order to maximize his upside as a big-league starter. Still, the Dominican left-hander was a solid pickup for Toronto.

At age 25, Ybarra doesn't have nearly as much upside as Aquino. He's also a lefty but pitches out of the bullpen, and is just as wild as Aquino. That said, he will likely reach the big leagues earlier than Aquino--which may have been Colorado's prime motivation in this transaction. Still, they could have done better here.

Aquino could be a long-range dark horse in keeper leagues, so he should now be on the fantasy radar in most leagues. As for Ybarra, he's a long shot to ever become a factor in fantasy leagues--though as a lefty reliever you never know for sure.
