The Diamondbacks have a good deal of depth at shortstop, as they feel that both Didi Gregorius and Chris Owings are capable Major League shortstops. In addition, three more names on Baseball America's list of Top 30 Diamonsbacks prospects — Nick Ahmed, Sergio Alcantara and Jose Munoz — are shortstops. This has led to some speculation that the Diamondbacks could trade a shortstop in order to address other needs in the organization, and Marc Carig of Newsday now reports (via Twitter) that the Diamondbacks have targeted young catchers in discussing shortstop trades with the Mets.
However, Carig adds that the Mets aren't a good fit for a trade with the D-Backs. Arizona is said to be seeking a Travis d'Arnaud type of talent in exchange for one of their shortstops and doesn't deem fellow catcher Kevin Plawecki a good enough return. As such, the Mets and D-Backs haven't had recent trade discussions about Arizona's shorstops (Twitter links).
For some context, Plawecki ranked fifth on BA's Top 30 Mets prospects heading into the 2014 season. BA calls him a safe bet to bat around .280 and hit somewhere in the range of a dozen homers at his peak level, and his bat is good enough to profile as a starting catcher, according to their scouting report. He has an average arm and is solid when it comes to blocking pitches, per BA.
The Diamondbacks currently have Miguel Montero installed as their everyday catcher, but the 30-year-old's offense slipped in 2013. After batting .283/.361/.457 from 2009-12, Montero slashed just .230/.318/.344 in 475 plate appearances last season. The decline was rapid and clearly unexpected, as it came in the first season of a five-year, $60MM extension that Montero inked in May 2012. He's set to earn $10MM this coming season, $12MM in 2015 and $14MM in 2016-17.
