The US Open 20 goal polo tournament showed up at Mashomack on Wednesday where a well-tuned Airstream won by a comfortable 13-7 margin over Postage Stamp. Airstream relied on the talents of two nine goalers with their superb horses and excellent team play. Most of the players seemed to be Argentine. The tourney continues at Greenwich.
