GLENDALE, Ariz. -- The focus of Thursday's White Sox bullpen sessions centered on John Danks and his continued comeback from Aug. 6 arthroscopic surgery.
But as important as Danks' bounceback is to the team's 2013 success, the continued development of young pitchers such as Jose Quintana, Hector Santiago, Nate Jones and Addison Reed stands just as important.
"I'm not sitting here thinking, 'Well, we've arrived,'" pitching coach Don Cooper said of four of the 10 rookie hurlers who pitched for the White Sox last season. "We've got more to do, more to improve, more to focus on and more to keep going.
"That was the thing we said pretty much all of last year. Just keep pushing along, whether it was a good outing or a bad outing or whatever, just keep pushing. Keep our eyes on the prize and where are we going, what do we need to do individually to get better?"
These four pitchers mentioned by Cooper will play integral roles for the 2013 squad. Reed returns as closer, with Jones' effectiveness maneuvering him into setup work, while Quintana rejoins the rotation and Santiago moves between starter and reliever.
Cooper understands that winning really is the only thing that matters at the big league level. He also understands the development component for the White Sox hurlers.
"For each guy, it might be different stuff," Cooper said. "They held up pretty well last year, so they passed the test. But you know what? There's a new test coming up this year. That's where our focus is going to be."
