White Sox left fielder Nicky Delmonico was removed after a nasty collision with shortstop Tyler Saladino while they attempted to catch a pop-up in the seventh inning of Sunday's 6-5 win over the Diamondbacks.
Delmonico was down on the field for a while but got up on his own. A Sox spokesman said Delmonico suffered a left shoulder subluxation, or a partial separation.
Manager Rick Renteria said he didn't think the injury was overly serious.
"Just extended it," he said. "Didn't pop it. Didn't do anything. Just got extended and jammed it a little bit."
Saladino also was removed from the game in compliance with the concussion protocol after he hit his head in the collision.
"We just took him out because he was real fuzzy," Renteria said.
Renteria said both were day to day and he would have more information Monday.
So far Sox camp has featured a series of injuries, including Luis Robert (sprained thumb), Micker Adolfo (sprained UCL in his elbow), Alec Hansen (forearm tightness), Jake Burger (torn Achilles) and Eloy Jimenez (left knee tendinitis).
Carlos Rodon is rehabbing from shoulder surgery, and reliever Jeanmar Gomez has a sore shoulder, according to Renteria.
"Nothing of concern for us," the manager said.
Rotation rundown: Reynaldo Lopez escaped a bases-loaded jam in the first inning and pitched 4 1/3 scoreless innings.
Lopez, who has an 0.96 ERA in three starts, didn't know which outing was his most impressive.
"All three have been good, because I can learn from each one of them," he said.
While Lopez has been the most effective of the five starters in camp, Hector Santiago also has been impressive and could still win a rotation spot if Carson Fulmer is sent back to Triple A.
Miguel Gonzalez will pitch a B game Monday, with prospect Dylan Cease starting the Cactus League game against the Mariners in Peoria, Ariz.
James Shields is expected to be the opening day starter in Kansas City, though Renteria hasn't revealed his decision.
"We're still working on it," he said.
Renteria knows who it probably is going to be. So what's the benefit of not revealing it?
"For us, just to let these guys continue to pitch," he said. "It has nothing to do with me trying to hide (it). We've talked to these guys what the possibilities are, but we haven't set it in stone."
