"Nothing serious, though, nothing to be worried about," Putnam said. "At this point in the spring, just being cautious and making sure it doesn't turn into something that'll start me on the shelf is the main goal.
"Maybe a little aggressive stretch and felt a little something. Like I said, nothing serious, not worried about it."
Jake Petricka also was working out Sunday after taking a John Andreoli line drive off of his right shoulder in the fifth inning of Saturday's game against the Cubs. Petricka said the line drive struck him somewhat square, but he got lucky in that it hit him in a good spot.
"Just going to be a little flesh wound, bruise," Petricka said. "Comebackers are part of it. You've just got to field your position.
"Good to go. Just blocked a shot like hockey, even though [Brett] Lawrie would have been there. I saw the replay, and I was like, 'Aw, if I could have gotten out of the way, it would have been an easy out for him.'"
Adam LaRoche has been dealing with back issues since he left a game eight days ago when it locked up on him. But White Sox manager Robin Ventura expects LaRoche to return to the lineup Monday against the Royals. Adam Eaton, who has only started at designated hitter in Cactus League play as he works through a throwing program related to his October left shoulder surgery, has a target date of March 23 to return to the field.
Ventura said that Eaton could play all over the outfield upon his return, with Austin Jackson primarily seeing time in center when he's out there and Melky Cabrera in left. Ventura also doesn't expect Eaton to have a tough adjustment in the move from center.
"It's easier than center just because you get an angle on it," said Ventura of Eaton playing left or right. "He feels comfortable either way.
"I'm not making it that he has to play one or the other. He will be able to move around, and he was pretty receptive to it. Even during BP, he'll go take fly balls in different spots in the outfield and looks pretty good."
