ST. LOUIS — Home Run Derby curse or not, Jazz Chisholm Jr. believes he is back. A month after taking part in the event, Chisholm is finally feeling like himself again and, in a small sample size, producing like the hitter he was heading into the All-Star break, at a time when the Yankees need it most.

Chisholm missed 28 games including all of May with an oblique strain and returned June 3 way ahead of schedule. Eight days later he came out of the June 11 game at Kansas City with left groin tightness and though the club saw him as being able to play through it, he was counseled not to push it.
