Riccarton trainers Michael and Matthew Pitman hold a strong hand in the open sprint on their home track on Saturday.

They will be represented in the Sonia & Garry Thompson Handicap by the in-form pair of Flying Ibis and Dynamic, with the latter getting the nod.

"Dynamic is such an honest horse and he is more of a 1200 metre type than Flying Ibis," Michael Pitman said. "He's come through the grades quickly and the claim helps."

Parvesh Shaikh will lighten Dynamic's load by two kilos and the apprentice has a fine record on the horse with three wins and two seconds from their last five outings.
