Neil Walker was the steady glove at second base for the majority of the season. He appeared in 101 of the first 103 games over the first four months before an injury forced Walker to end his 2012 season early. Walker was diagnosed with a herniated disc in his low back, which forced his to miss 16 straight games from August 27th-September 4th. Manager Clint Hurdle called upon rookie Brock Holt, who filled the void primarily in his absence during that stretch.
Overall, Walker missed 27 of the final 35 games attempting to battle through the injury while several players got looks at the position. Walker will be arbitration eligible this season, and there has been no current updates on a long-term contract extension as of the end of the season.
