The rosters for each of the World Baseball Classic teams were announced, Friday and the San Diego Padres were well represented on several teams. Mason Miller will play for the US, Manny Machado, Fernando Tatis Jr. and Wandy Peralta for Dominican Republic, Xander Bogaerts for Netherlands, Yuki Matsui for Japan, Ron Marinaccio and Alek Jacob for Italy, Carter Loewen for Canada, Josh Mallitz for Israel and Miguel Cienfuegos for Panama. It is an honor and in some cases a dream for these players to compete for their country, but with so many players leaving during Spring Training to compete in the WBC, there is concern about how productive they can be for the Padres.
