Zifena gave Eve Johnson Houghton’s Blewbury stables, near Didcot, a valuable success at Newmarket on Saturday.
The two-year-old filly sprang a 20-1 surprise when collaring hot favourite Enlace by a head in the final strides of the six-furlong nursery under Jim Crowley to capture the first prize of £25,876.
Meanwhile, Wantage trainer Henry Candy landed an across-the-card double with Lady Pimpernel at Newmarket and White Russian at Lingfield.
Lady Pimpernel (7-2) beat Tanseeb by a length and a half in a mile and a quarter handicap, with Fergus Sweeney on board.
And White Russian, ridden by Hayley Turner, held off Ziggy’s Secret by a neck in a seven-furlong handicap.
