RESERVE Tank dug deep to cause an upset in the Grade 1 Betway Mersey Novices’ Hurdle at Aintree.

After only hinting at promise on his first two starts over hurdles, the Colin Tizzard-trained five-year-old has really turned a corner since the turn of the year – registering successive wins at Sandown and Kempton.

However, he faced a significant step up in class for this two-and-a-half-mile affair and was priced-up as a 20/1 shot under Robbie Power.

Reserve Tank travelled strongly on the heels of the leaders for much of the race and jumped to the front three flights from home.

Brewin’upastorm – fourth in the Ballymore Novices’ Hurdle at Cheltenham last month – did his best to close the gap, but Tizzard’s charge found extra from the last hurdle to prevail by three and a quarter lengths.

One For Rosie and 11/4 favourite Angels Breath dead-heated for third.
