Aqueduct: Another winning Parx shipper


  These days, shippers from Parx Racing are automatic contenders when they ship in against the local claiming stock.

   Sister in the City ($9.00) came in to take a $14,000 filly-and-mare race yesterday.

   Today's Parx play was Tiffany Rock ($4.80), who pressed the pace inside and drew away to beat $7,500 mares first out since Dec. 11.
