Diamondbacks' Daniel Descalso: Out as usual against lefty As usual, Descalso's platoon partner Deven Marrero will get the start against a lefty, as the Diamondbacks face southpaw Clayton Richard. With Jake Lamb (shoulder) nearing a return from the disabled list, the platoon arrangement should end soon, sending Descalso back to a bench role.
