Viciedo may go on rehab assignment soon

KANSAS CITY -- Outfielder Dayan Viciedo continues to make steady progress as he works to get back in the White Sox lineup.

Viciedo has been on the disabled list with a left oblique strain, but manager Robin Ventura said Viciedo may be ready for a rehabilitation assignment in the near future.

"There's a chance, in the next few days, that he would be going out," Ventura said.

Viciedo has taken swings during the team's stay in Kansas City with no ill effects.

Peavy 'highly doubtful' he'll make Monday start

KANSAS CITY -- So much for Jake Peavy's confidence about starting for the White Sox on Monday. A pregame session of catch did not go well for Peavy on Saturday, and the right-hander said it's "highly doubtful" he'll be able to start against the Royals on Monday in the final game of the three-game series.

Peavy, who experienced back spasms Thursday in Texas, had more back issues as he tried to play catch.

"Unless we have a really good day [Sunday] and things turn quick, I'm highly doubtful for Monday," Peavy said.

Peavy has worked with a chiropractor in Kansas City, but said the back is "still grabbing pretty good when I'm throwing the ball."

Manager Robin Ventura said it could be Chris Sale or someone else making Monday's start. That decision was still being discussed late Saturday evening.

"If [playing catch] is a problem, then certainly throwing 100 percent off the mound is going to be," Peavy said.

Peavy will continue to work with the chiropractor and receive treatment on Sunday.

"Hopefully, we can get it knocked out," Peavy said. "I certainly don't want to spend any time on the DL or be out any more than I already have been."

White Sox latest stop on Wells' whirlwind tour

KANSAS CITY -- The visiting clubhouse at Kauffman Stadium has been a familiar landing spot for Casper Wells during his whirlwind tour of the American League this season.

The new White Sox outfielder has been with four organizations since Spring Training. The saga took him from the Mariners to the Blue Jays and then to the A's and White Sox. Wells reported to the Blue Jays three weeks ago when Toronto visited Kansas City. He attended a meet-and-greet team dinner with the Blue Jays during an off-day, but was released a few days later. He landed in Oakland for a brief span before the White Sox acquired him on April 29.

All the movement hasn't dissuaded Wells, who appreciates how special it is to wear a Major League uniform.

"You really just look forward to each day and the opportunity you have before you," Wells said. "You meet different guys and it's still about playing the game of baseball. The White Sox have welcomed me to their club, but obviously it takes some time to have some success, contribute to the team and feel that camaraderie.

"Hopefully, I can help this club and everything works out here. I just feel very blessed to do what I do."

White Sox announce pair of doubleheaders

The White Sox-Indians game that was postponed on April 23 will be made up as part of a straight doubleheader on June 28. The opener begins at 4:10 p.m., with the nightcap starting 30 minutes after the conclusion of the opener.
