Harry Marshall, the Co Antrim rider who threatened not to jump at Kerrygold Dublin in August after a dispute with the selectors, scored a brilliant double on the closing day of the Cavan indoor international, taking the Power and Speed with Ollies Party Piece and then clinching the leading rider award with a stylish victory in the Aer Rianta Grand Prix on Cruiseline.

Marshall, who had a change of heart at Dublin and duly won the opening international with the mare he calls "my baby" drove home to Ballyclare on Saturday night, but returned yesterday determined to avenge his defeat at the hands of 18-year-old Robert Power 24 hours earlier.

With Ollies Party Piece tuned and ready, Marshall pinned Eddie Dermody down in the runner-up spot for the Power and Speed and then brought out Cruiseline to claim the big money in the Grand Prix with the only clear round of the four-horse jump-off.

Swiss-based rider Cameron Hanley opened the batting with Wandonga, but a rail off the second part of the double left the door open for his three rivals and, although Cian O'Connor failed to take advantage with two down, Marshall was clear and left last man, Stevie Macken with it all to do.

Macken, the 22-year-old son of Eddie, had already slotted FAN Sky View into second on Friday night, but stable mate FAN Schalkhaar, which earned Eddie his first Dublin Grand Prix win three years, ago, took an early rail to drop to third behind Hanley.

Clement McMahon, who missed out on the timed round with a single error at the final double in the first round, still slotted into ninth to seal overall victory in the Horsepower Ireland indoor league, which had run over seven rounds in the build-up to the Cavan final.

McMahon was riding Ann McArdle's Touchdown mare, TOP Brackley Rose Down and the £2,500 Horsepower prize is to be split between owner and rider.
