Dibaba N ($4.20, Jon Roberts) was a 1:53.2 winner in the featured $12,000 Mares Open Tuesday at Harrington Raceway.

 Trained by Dylan Davis for owners Robert Cooper, Howard Taylor, J&T Stables and VIP Internet Stable, the Shadow Play 6-year-old mare notched her first win of the year with an off the pace triumph over My Last Bet and Ideal Lifestyle A. Scuola Hanover set sizzling fractions of 26.1, 54.3, and 1:23.1 before retreating through the stretch. Dibaba N angled off second-over cover in deep stretch and hit the wire first as the race favorite.

 Allan Davis had four wins on the program, after winning three on the Monday card.

 Roberts, Ross Wolfenden and Tony Morgan each had a driving double.
