Jeff Keppinger doesn’t anticipate his shoulder irritation will be a lingering issue. Keppinger’s status qualifies as good news for the White Sox, who have had a few recent minor injuries. The third baseman, who started at designated hitter Sunday in his first appearance since March 9, is expected to return to the field Tuesday, per manager Robin Ventura. But Keppinger, who first sat out with right shoulder irritation and then missed three days for a personal matter, believes his body continues to heal properly. Since his arrival, Keppinger has anticipated his shoulder might take longer to prepare because he wasn’t able to begin his throwing program until he arrived in camp. Keppinger was behind schedule because he needed the entire offseason to rehab a broken fibula he sustained in November. The White Sox have taken it slow with the free-agent signee thus far, rotating him between DH and the field. “I don’t have an issue with my shoulder where it’s going to be a problem all season long,” Keppinger said. “There’s a little irritation and inflammation in there from just picking up the use really fast where in the offseason I didn’t much time to build it up. I’m pretty sure it’s taken care of and we’ll move forward from here. You just have to work through things. Certain things are going to hurt and ache. And the more you push through them, your body adjusts.”
