Alan Spence's son of Exceed And Excel had been of the track since last August but this proved no barrier to him and he ran out an easy winner under William Buick.
Buick kept it simple, settlling Double Up on the heels of the leaders. Double Up picked up well when asked and soon skipped clear to win by three and a quarter lengths.
Roger said: "Double Up has always shown plenty of potential at home so it was great to see him win well on the track.
"That should have boosted his confidence and hopefully there is more to come from him."
