• In an MLB.com mailbag, T.R. Sullivan suggests that Frank Francisco could be a prime trade candidate in July, particularly if the Rangers are slipping from playoff contention.
• Luis Mendoza cleared waivers and accepted an outright assignment to Triple-A Omaha, tweets Bob Dutton of the Kansas City Star. Mendoza was designated for assignment by the Royals last week.
• GM Jim Hendry says prospect Starlin Castro will join the Cubs at some point this season, but he won't say how soon, according to ESPNChicago. A source told Bruce Levine of ESPNChicago earlier in the week that Castro's promotion could be right around the corner.
• ESPN.com's Rob Neyer doesn't think the White Sox have any need for Jermaine Dye. We heard earlier today that Dye believes he'd be a fit for the South Siders.
• Talking to Tom Krasovic of AOL FanHouse, Brewers outfielder Jody Gerut explained why the Padres should retain Adrian Gonzalez. 
• Rockies outfielder Carlos Gonzalez answered questions from Denver Post readers, explaining that "it's a really bad feeling when you get traded" and he'd like to sign a contract "for a few years."  Gonzalez is not arbitration-eligible until after the 2011 season, and he's represented by Scott Boras.
• The Yankees are not typically inclined to sign young players to long-term deals.  It makes sense to maintain flexibility, as they did going year-to-year with Chien-Ming Wang.  On the other hand, Joel Sherman of the New York Post points out that Robinson Cano's extension has worked out quite well.  Will the Yankees exercise his $14MM club option for 2012, or choose the $2MM buyout?
