When the Mets saw their starting infield and their new catcher depart for the World Baseball Classic, manager Buck Showalter’s main focus was on getting them all back in one piece.

But Showalter and general manager Billy Eppler also saw an upside to the departures of stars such as Pete Alonso and Jeff McNeil (USA), Francisco Lindor (Puerto Rico) and Omar Narvaez and Eduardo Escobar (Venezuela): It would let them get an even better look at some of the organization’s top prospects.

Though infielders Brett Baty, Mark Vientos and Ronny Mauricio, along with catcher Francisco Alvarez, each got plenty of playing time in the early stages of spring training, Eppler said recently in Port St. Lucie, “The silver lining of the WBC is it gives them an opportunity to show what they can do, especially as opposing pitchers get deeper into their arsenals.’’
