Arnhem justified favouritism in good style in Dundalk's apprentice handicap over six furlongs.

Gavin Ryan did the steering on the 5/2 chance who was supported down from 6/1 during the day.

He broke well from stall five and soon tracked That's Not Me before edging ahead of that rival inside the final quarter of a mile.

He was ridden to assert coming to the final furlong and ran on well to strike by a length and three quarters.

A staying-on Jered Maddox chased the 'jolly' home at 11/1 with St George's Head in third at 18/1.

"He won well. We thought last week that the penny had finally dropped with him,” said trainer Natalia Lupini.

“He's shown his best form over seven furlongs, we always thought he was more of a sprinter but he just took his time to get there and was just a bit immature.

“He won easy and we're delighted. He's genuine and always tries very hard.

“We'll see how he comes out of this but we'll probably run him again and then I think he'll go for a break.

“I'd say he'll be a solid sprinter next year.”

Arnhem had finished third on his last two visits to the Polytrack in seven-furlong races.

The Stewards interviewed L.T. McAteer, rider of That's Not Me, concerning the fact that he appeared to move across before reaching the marker poles. Having viewed the recording of the race and considered evidence, the Stewards found the rider in breach of Rule 211 (a)(Marker Poles) and having taken his record into account suspended him for one race day.
