Josh Rutledge will be the Rockies' primary second baseman when Troy Tulowitzki (groin) returns. Rutledge has impressed the Colorado coaching staff in his time filling in for Tulo at shortstop, so they'll keep the 23-year-old as active as possible down the stretch. He is batting .329/.347/.581 with seven home runs and 27 RBI through his first 46 major league games, and should retain his fantasy value in mixed leagues.
