BOSTON -- A trade of Boston Red Sox infielder Kevin Youkilis could happen at any time now, two officials involved in trade talks told ESPN The Magazine's Buster Olney. On Friday night, the Chicago White Sox were perceived to be one of the frontrunners.

The Red Sox have talked with the Los Angeles Dodgers, Cleveland Indians, Atlanta Braves and Arizona Diamondbacks about Youkilis, among other teams. One executive involved indicated on Friday night the White Sox were thought to be competing with an NL team, and the Red Sox were going through the process of trying to nudge offers one last time.

Arizona is said to be out of the running. The Braves reportedly have scouted Youkilis repeatedly in the past week.

Red Sox manager Bobby Valentine said he talked with Youkilis on Friday about decreased playing time. Youkilis, while not happy about it, understood Valentine's decision.

"He doesn't necessarily totally agree with it and doesn't wake up in the morning and hope that's the case, but I think the professional person that Kevin is, he understands it," Valentine said. "Yes, I think he's fine."

For the first time since coming off the disabled list on May 22, Youkilis is out of the starting lineup for two consecutive games. The fact that it comes in the wake of a monster performance by fellow third baseman Will Middlebrooks on Thursday night begs the question: Has there been a concrete shift at third base from the veteran Youkilis to the rookie Middlebrooks?

For Friday night's series opener against Atlanta, Valentine said he's simply going with the guy who is swinging a good bat.

"Today, I'm riding the hot hand," Valentine said. "Tomorrow might not be the case. I always reserve the right to change my mind."

But Valentine did say he had a discussion with Youkilis about the situation and expects his veteran to adjust to any part-time role that emerges.
