DENVER -- Results were not immediately available from an MRI on the left hamstring of Rockies catcher Ramon Hernandez, who had to leave Monday night's game. However, the injury did not look good as Hernandez was being led off the field by the Rockies' training staff. "I didn't like the gait, I can tell you that," manager Jim Tracy said. Hernandez was starting because of rookie Willin Rosario's recent defensive struggles, which included five passed balls in two games. After replacing Hernandez, Rosario let a blockable Guillermo Moscoso breaking ball squirt between his feet for a wild pitch.
Tracy said Monday that Rosario's passed balls were unacceptable. On Tuesday, Tracy expressed faith in Rosario. "He's making strides," Tracy said. "I'm a big fan of this kid. All I have to do is watch the effort that he gives every day, know that he wants to learn, know how I've sat here over the last three-plus years and taken some beatings because of Dexter Fowler, 'Why is he hitting left-handed?' and 'How much longer are you going to play Carlos Gonzalez?' Those windows take a little time. You have to have the patience and the courage to endure the lapses that are going to come along with it. "This is another case that I really believe we will finish this project. He may make a liar out of me. So what? I don't think he will, just like I didn't think Fowler would and I didn't think Gonzalez would." First baseman-third baseman Jordan Pacheco and recent callup Matt McBride, who plays first and in the outfield, have caught some this season and will be Rosario's backups.
