SAN FRANCISCO -- Rockies manager Jim Tracy hopes all of the conversation about rookie catcher Wilin Rosario doesn't center on his passed balls. Rosario entered Wednesday night's game against the Giants with 25 homers -- most among National League rookies and tied with Todd Helton (1998) for the club rookie mark. D-backs pitcher Wade Miley, the Nationals' Bryce Harper, the Reds' Todd Frazier and the Cubs' Anthony Rizzo will be in the NL Rookie of the Year conversation. Tracy believes Rosario's name should come up, as well. "To just take that and not mention him as a guy to be considered as a Rookie of the Year candidate?" Tracy said. "To me, that's a little unfair. We still have 15 ballgames left and this guy has 25 home runs. That's quite an offensive season, with 300-some-odd at-bats. That's why we're going to keep working real hard behind the plate."
