NL Central: Garza, Wigginton, Cardinals, Braun

In today's column, Buster Olney of ESPN.com (Insider sub. required and recommended) explains that many teams have "Zack Wheeler Syndrome" as they approach the deadline.  As he describes it, It’s the tendency of GMs to wait for a club to get desperate and overpay for a player.  That's what the Mets were able to do in 2011, when they demanded that they get a top-tier prospect in return for Carlos Beltran and wound up prying Wheeler from the Giants.  Today, one exec tells Olney that the asking price for the Cubs' Matt Garza (as well as the Yankees' Phil Hughes) is "incredibly high" because of that thinking.  Chicago knows they will at least present a qualifying offer to Garza after the season if they keep him, which will net them a compensatory draft pick if he signs elsewhere.  Anyone who wants to land Garza has to match, and probably exceed, the value of that pick.  Here's more out of the NL Central.. 

• Ty Wigginton wound up as the low man on the totem pole with the Cardinals, writes Rick Hummel of the St. Louis Post-Dispatch.  While his disappointing tenure in St. Louis ended with his release yesterday, manager Mike Matheny is an adamant supporter of the veteran and says that his career is far from done.
• The Cardinals made reliever Mitchell Boggs available because he has struggled so far in 2013, but he could bounce back and regain his 2012 form, writes Troy Renck of the Denver Post.  St. Louis shipped Boggs to the Rockies yesterday for roughly $206K in international bonus slot money.
• The Biogenesis suspensions could make for a messy second-half of the season, writes Jon Paul Morosi of FOX Sports.  However, despite the negative attention surrounding the Brewers' Ryan Braun, Alex Rodriguez, and others, the game has been quite resilient through this and other PED scandals.
