"We wanted to get another right-handed reliever here," Blue Jays manager John Farrell said about the decision. "With today and a predominantly right-handed-hitting team in Texas and the Angels [who the Blue Jays play next] are going to be the same type of lineup, where there's primarily right-handed hitters throughout. That's where we felt another right-handed pitcher was needed. Evan was the guy who was the optionable reliever. It had nothing to do with performance or anything like that."
Carreno made his first career start against Cleveland on April 8 and lasted six innings while surrendering four runs in the loss. He was optioned to Triple-A following that outing, and in four starts with the 51s, he went 2-2 with a 6.20 ERA.
Crawford, meanwhile, had been brought up to Toronto on two different occasions -- most recently when Sergio Santos was placed on the disabled list. Over five appearances out of the bullpen, Crawford posted a 4.50 ERA.
