ML blown call?

[alex7]

From today's Pirates/Rockies game:

"Delwyn Young swung and missed at Jhoulys Chacin's 0-1 cutter for strike two, but the ball hit Young on the leg and ricocheted toward the Pirates' third-base dugout. Rockies catcher Chris Iannetta asked home plate umpire Mike DiMuro for a new ball not knowing the original ball, ruled a wild pitch, was still in play. A heads-up Doumit raced home before Iannetta knew what had happened."

The runner from 3rd scored on this play. Reading the "pitch hits batter on hand on 3rd strike thread", the recurring theme was that anytime a pitch hits a batter while swinging, it's a dead ball.

Is this just at the HS level? Or did DiMuro and his crew somehow miss an easy one?
