Eugene Landy's Sassa's Sister ($46.60, Trae Porter) was an upset winner in the $20,000 Mares Open Tuesday at Harrington Raceway.

 The Jim Porter-trainee catapulted to the lead in deep stretch, holding off Moments of Joy and Anytime N for her 4th win of the year.  "Sister" fanned out wide from third-over position and surged through the stretch to spring the upset.

 It was the second straight win on the card at long odds for that same driver/trainer/owner combo, who also won with You Beda Rock ($18.20) in the race prior.

 Trainer Clyde Francis, owner George Teague and driver Montrell Teague scored a double with Rowdy Rousey ($10.60) and Dirty Shirley ($16.80).

 Allan Davis and Art Stafford Jr. each had a driving double.
