Overturn has booked his Cheltenham ticket with another superb display to keep his unbeaten record over fences intact in the Scottish Arkle Novices' Chase at Musselburgh.
Donald McCain's dual-purpose performer, sent off the 1-5 favourite following impressive rounds of jumping at Sandown and Doncaster, adopted his customary front running tactics and even with a circuit to go it was clear main rival Tetlami was struggling to keep tabs on him.
Jason Maguire continued to wind up the tempo heading down the back and by the time he rounded the final turn Overturn was well clear. He safely negotiated the remaining obstacles in the straight to score by an emphatic 29 lengths from Tetlami, the only other finisher.
"He was smashing and Jason said he was magic," McCain said.
"We always looked for a reason not to send him chasing. If he'd made one mistake at home we wouldn't have done it. He enjoys it, that's the main thing.
"He will go straight to the Arkle. He's won on three different types of track now and that will stand us in good stead for a month's time."
Paddy Power trimmed Overturn to 7-2 from 4-1 for the Arkle Trophy at next month's Cheltenham Festival, a race for which Tetlami's stablemate, the Nicky Henderson-trained Simonsig, is 4-6 favourite.
