Quick Hits: Diaz, Lohse, Yankees, Chamberlain, Cubs

Major League Baseball's investigation into the age of Cuban shortstop Aledmys Diaz is still ongoing, multiple sources tell Ben Badler of Baseball America.  Diaz has been presenting himself as a 23-year-old, which would make him exempt from the international bonus pools.  However, previous documentation of his age would indicate that he is 22 or possibly as young as 21.  If MLB determines that Diaz presented any false documentation, the league could declare him ineligible to sign for one year.  Here's more from around baseball..

• Kyle Lohse has only his union to blame for his predicament, opines Brian MacPherson of The Providence Journal.  Because the players' association gave in to owners' demands that draft bonuses be reined in, teams are more protective of their draft picks than before.  Yesterday, ESPN.com's Buster Olney wrote that AL talent evaluators are concerned about his track record in the league.
• Yankees pitcher Joba Chamberlain has re-opened the debate on whether he would be better utilized as a starter or a reliever, writes Mark Feinsand of the New York Daily News.  The Yanks avoided arbitration with the oft-injured hurler on a one-year deal this winter that includes a bonus for games finished.
• Kerry Wood is getting a taste of coaching with the Cubs in spring training, but he has no aspirations of pursuing it as a full-time job right now, writes Jesse Rogers of ESPNChicago.com.
• Cubs president Theo Epstein would obviously like to see his club be competitive in 2013, but he will quickly discard his short-term assets if the playoffs aren't in sight, writes David Haugh of the Chicago Tribune.
