HONGKONG'S Roderick Staunton shot a one-under-par 55 in the second round of the Junior World Golf Championships in Presidio Hill, San Diego yesterday.

But it was not enough to maintain his overnight lead as American Mark Rosenseltus leapt to the top with a four-under-par 51 for a two-round total of 106. Staunton is in second place by a single shot with one more round to go in the 10 and under category.
