J&M Racing Stable's Embassy Seelster ($10.80, George Dennis) set a new track record for aged pacing mares with a 1:51.3 triumph in the $12,500 Mares Open II at Harrington Raceway.

 The Doug Lewis-trainee led most of the way in her half-length victory over San Fran Lady N and Star Keeper. The 5-year-old Modern Art mare reset the track record, formerly held by Ladyfield (1:51.4) set in 2008. It was also a new national season's mark for hpacing mares in North America on a half mile racetrack.  Also Encouraging ($2.10, Jim Morand), a top sophomore filly from last year who made $316,761, returned for her first win in her second start of this season for owners Richard Lombardo and David Kryway with a 1:53.3 score for trainer Josh Green.

 Another talented mare on the comeback trail notched her first 4-year-old win as CC Racing's Tyra ($4.80, Victor Kirby) capitalized on a class drop for a 1:54 win in a $10,000 conditioned pace. Trained by Jim King Jr., the 4-year-old Mcardle mare was a beaten favorite in Open company last week but helped to atone for that defeat with her first win in three starts this year.

 Dennis had three wins on the program.
