The Chicago Cubs have a laundry list of questions that need answering in the next few seasons when it comes to the makeup of their roster. But seemingly it looks like the Cubs have found a long-term solution behind the plate. Welington Castillo entered the 2013 season after he played 52 games the year before and batted .265. 108 games later nearly all of Castillo's numbers have improved and he's proved himself as Chicago's starting catcher for the foreseeable future as a result of what fellow backstop Dioner Navarro sees as his most valuable trait. "His work ethic he’s a hard worker" Navarro said. "He’s smart behind the plate he knows what he’s doing. He goes and he reads the scouting reports and all the stuff." Navarro knows what it's like to break into the big leagues with a lot of pressure. He was the New York Yankees' top prospect prior to the 2004 season and sees a bright a future for Castillo after Castillo supplanted Navarro as the Cubs' starting catcher this season.
