Assigned the outside post six in the $1,300 eighth race, Dirt Track Momma fired to the lead and carved out fractions of :28.2, :57.2 and 1:26.3 en route to the 1:55.3 triumph. The winning margin was eight and three-quarter lengths with Putnams Glory coming in second and Dance Hanover finishing back in third.
Dale Spence drove the record-setter for owner and trainer Jonah Moase of Cornall, P.E.I. -- the same connections who teamed up with Big League to establish an all-age track record of 1:53.4 this summer.
Dirt Track Momma paid $2.70 to win as the race favourite.
