GLENDALE, Ariz. – A healthy John Danks can make the White Sox’s strength even stronger.

Pitching coach Don Cooper and the Sox are cautiously optimistic after Danks’ first bullpen session Thursday at Camelback Ranch. The session lasted about 10 minutes with Danks using four pitches. Danks said he felt good during and after the bullpen, which had Cooper, manager Robin Ventura, general manager Rick Hahn and executive vice president Ken Williams watching.

“At this point, it’s just trying to get back to where you’re completely healthy,” Danks said. “I felt good, and the next step will be to start worrying about pitches. But right now it’s still proving to everybody that I’m 100 percent healthy.”
