The adjustments left Jeter frustrated, as he batted .242 in the first month of the 2011 season. As he struggled, it appeared that the 2011 season was the continuation of Jeter's decline. Jeter broke Rickey Henderson's franchise record for stolen bases when he stole his 327th base against the Mariners on May 28, 2011. He suffered a calf injury on June 13 that required his fifth stint on the 15-day disabled list, and his first since 2003. At that point, he was batting .260 for the 2011 season with a .649 OPS. Rehabilitating from his injury in Tampa, Jeter worked on his swing with Denbo, his former minor league manager. With Denbo, Jeter returned to the mechanics he used in his minor league days. Following his activation from the disabled list, he hit .326 with an .806 OPS in his last 64 games of the season. Jeter finished the year with a .297 batting average, 6 home runs, 61 runs batted in, 84 runs, and 16 stolen bases. He credited the turnaround to his work with Denbo; Long acknowledged that his attempt to adjust Jeter's swing did not work.
