GLENDALE, Ariz. -- White Sox third baseman Todd Frazier will be sidelined at least a few days with a sore left side.
Frazier felt some tightness on Tuesday, and did not participate in Wednesday's workout at White Sox Spring Training at Camelback Ranch.
"That's what Spring Training is for," Frazier said. "I don't feel it's anything that serious. Since we have so much time, let's take a break, take a few days off and hopefully it keeps getting better and better.

"It's not something I'm really worried about. It comes with the territory."
Frazier said it is likely an oblique issue, though the team's medical staff hasn't made an official diagnosis.
"It's something I've dealt with before, but from what I've heard, it's not anything to mess with," said Frazier, who attributed the soreness to not swinging a bat much during the offseason.

Manager Rick Renteria said Frazier, who hit 40 home runs and drove in 98 runs last season, is considered day to day, as the White Sox prepare for their Cactus League opener Saturday against the Dodgers.
"We'll re-evaluate and we'll see where he's at," Renteria said. "We'll see where he's at before I determine how far I have to push him back."
Worth noting
• Getting back to some of baseball's basics is a staple for every team this time of year, and that is certainly the case in Renteria's first season at the helm of a squad that committed 95 errors last season, and often struggled in certain situations offensively.
"We're talking about it a lot," Renteria said. "A lot of it is focus and preparation. So hopefully we can increase our intensity and concentration on certain situations without getting uptight.
"Right now, when we're running the plays, the defensive fundamentals and the situational hitting, the results in the controlled environment, they actually occur. That's an indication guys are doing what they're supposed to be doing. It's a little more hectic when you get into a game, velocities increase and emotions get into the picture. But if they can at least at this point, in the controlled environment, master the environment in which they're working, that starts to show indications that they're going to be able to do it moving forward."

• Renteria declined to announce who will start Saturday's Cactus League opener.
