His season was interrupted on July 9 against the Pirates. While sliding past third base, he attempted to grab the bag to stay on. However, during the play, he injured his right thumb. An MRI revealed torn ligaments, requiring surgery and forcing him to miss the next eight to 12 weeks. Regarding the injury as having a significance impact on the Cardinals' season, "St. Louis Post-Dispatch" sportswriter Bernie Miklasz commented, "Losing the best catcher in the world for the next 8 to 12 weeks with a torn thumb ligament is a horrendous, demoralizing setback for the Cardinals. This could be a season-ending injury." At that point, he was batting .287 with a .341 OBP, .409 SLG, 16 doubles, seven homers, and 30 RBIs through 83 games. He also led MLB with a 49 caught-stealing percentage.
