Mike Broadway was sent to the minors on Saturday, opening a slot for Mazzaro. He is at best a middle inning reliever for the Giants. You can safely ignore him on the wire.
Dickerson will hit the pine as he does not fare well against southpaws. With J.A. Happ on the mound Saturday, Steven Souza will replace Dickerson in the Rays' lineup at DH.
With the team activating Jared Hughes on Saturday, Scahill is getting sent out to Triple-A. Scahill was not effective at the major league level and will head back to minor to await a future call up.
Hughes has been dealing with a lat injury, but will now be joining the Pirates bullpen. He is noting exciting in terms of fantasy production, being more a real life asset than a guy you want to target off the waiver wire.
Hahn gets the start on Saturday, replacing Andrew Triggs on the roster. He has posted a fine 2.04 ERA with 13 Ks in the minors so far, and thus is a decent option for a spot start.
Triggs has been bouncing between Triple-A and the majors in April. Jesse Hahn has been recalled to start on Saturday, and thus Triggs heads back down to Nashville.
