Four divisions of the New York Sires Stakes for three-year-old trotting colts and geldings went postward Friday evening at Vernon Downs, and it turned out to be a big night for sons of Chapter Seven. That sire produced three of the divisional winners on the card including Ahundreddollarbill, who rolled to a 1:52.2 triumph in his $56,000 assignment. Andrew McCarthy parked through an opening quarter of :27.2 before finding the lead with the Tony Alagna trainee. Once in charge, the youngster sailed through middle splits of :56 and 1:24.4 before using a :27.3 closing panel to seal the deal. He held on to win by one-quarter of a length over Incommunicado. Dewey Arnold was third.
