Mitchell Boggs gave up his first run of the spring Saturday after earlier learning he was likely to open the season as the Cardinals' closer. We trust Trevor Rosenthal and Fernando Salas at least as much as Boggs, but it's clear Boggs is Mike Matheny's choice to replace Jason Motte in the closer's role for now. It should give him quite a bit of fantasy value initially. How long it lasts depends on Motte's arm.
