GLENDALE, Ariz. -- Although Simon Castro, Scott Snodgress, Erik Johnson and Nestor Molina won't be part of the White Sox rotation at the outset of the 2013 season, they will be valued Minor League starters. With that in mind, they White Sox are keeping this quartet on a work schedule of every five days.
"Then when we hand them off to our Minor League people, it won't be going from one inning and now we have to get him to six," White Sox pitching coach Don Cooper said. "We'll hand off the baton to those guys, and right now they are in a good spot to where when we make cuts and get there, it's going to be an easier transition to go and get ready for their season.
"I want to give them everything they can get out of Spring Training," Cooper said.
Johnson (No. 3), Snodgress (No. 6), Molina (No. 10) and Castro (No. 16) all rank among the White Sox top prospects.
Castro made his second impressive Cactus League outing during Monday's 6-2 victory over the Giants. The right-hander worked the sixth and seventh, striking out five, while yielding just one hit. In five spring innings, Castro has yielded two hits and fanned eight.
"Stuff is good, changing speeds. Velocity is good. Aggressive throwing strikes, all of the things we wanted anybody to do," Cooper said. "He's thrown as good as we've seen him throw."
"He's more polished and just a better idea of what he's doing out there and more control," White Sox manager Robin Ventura said. "I think it just comes with maturity."
