Lisa Photo (CLICK TO VIEW) Another Saturday night, another harness racing world record comes under assault at Mohegan Sun at Pocono Downs.

This time around, it was the mark for 4-year-old trotting stallions on a 5/8-mile oval that was obliterated by star trotter Uncle Peter in the Preferred trot on Saturday night.

The winning time of 1:51:1 smashed the track record for 4-year-old stallions on the trot of 1:52, set last May by Fox Valley Iliad, and that mark was also the world record for the age group on any 5/8-mile oval.
