ARLINGTON -- Rockies manager Jim Tracy is closely monitoring playing time of many of his veterans, so he's happy to have spry, young rookie catcher Wilin Rosario. Tracy started Rosario on Friday night against the Rangers for the sixth time in seven games on the road trip, and it was Rosario's 39th start. He has started all but six of the 26 games since Ramon Hernandez went to the disabled list with a left hand strain. Rosario entered Friday leading Major League rookies, as well as National League catchers, in home runs with 11, and his 32 RBIs put him ahead of all other Major League rookies. The Red Sox's Will Middlebrooks trailed him by one.
Tracy said Rosario, 23, will take a break Saturday afternoon, but wear and tear is not an issue. Tracy said the amount of playing time Rosario has been forced to eat up has helped his learning curve. "This is not a problem," Tracy said. "There is no greater teacher than exposure. We can sit here and talk about it, but that's not going to replace the guy actually going out there and having to deal with the game. You have a game plan for a specific hitter, the game plan starts to unfold, the hitter gets to two strikes, he fouls two or three pitches off. Do you have the wherewithal to understand what the swings are telling you and what the next place is that you have to go?"
