Julie B's unfamiliarity with a wet track didn't pose any problem as she posted her third consecutive stakes victory Saturday night in the $51,350 My Sister Pearl at Charles Town. Racing on a non-fast track for only the second time in her 36-race career, the 5-year-old Julie B ($3.40) defeated Saxet Heights by 1 ½ lengths while completing 1 1/8 miles over a sloppy, sealed surface in 1:55.81. Larry Reynolds rode Julie B for trainer George Yetsook and owner Randy Funkhouser's O'Sullivan Farms. Shesagrumptoo, runner-up to Julie B in last month's $500,000 West Virginia Cavada, finished fifth at 5-1.
