Red Sox trade rumors: Koji Uehara, Will Middlebrooks, Mike Napoli, Daniel Nava placed on revocable trade waivers

After being the most aggressive seller at the non-waiver trade deadline by shipping out seven veteran players including John Lackey and Jon Lester, the Red Sox may not be done dealing. According to Nick Cafardo of the Boston Globe, the Sox recently placed closer Koji Uehara, outfielder Daniel Nava and infielders Will Middlebrooks and Mike Napoli on revocable trade waivers. They join left-hander Craig Breslow and infielder Kelly Johnson as Sox players who have reportedly been placed on waivers this month.

Though Napoli and Middlebrooks should be considered unlikely trade candidates, there's a chance that Nava or Uehara could be traded in the two weeks before the waiver trade deadline on August 31. Nava has reportedly drawn interest from the Tigers and Royals in recent weeks, with Detroit seeming to be the more likely destination for him now that Kansas City has added Josh Willingham in a trade with the Twins. After struggling to begin the season and being demoted to Triple-A, Nava has worked his way back to a .267/.342/.342 slash line in 75 games and is appealing to teams because he is under team control for three more seasons.

Uehara is a free agent after the season and will almost certainly be claimed by a team looking to add a back-end bullpen piece for the stretch run. The All-Star has posted a 1.23 ERA while saving 47 games in 132 innings with Boston over the last two seasons, and has expressed a willingness to re-sign with the club once he hits free agency this winter. It is possible that the Red Sox could trade him to get something back in the midst of a lost season, while the goal of re-signing him this offseason in mind.
