She was sired by Kodiac,[1] a sprinter who won four minor races from twenty starts and finished second in the Hackwood Stakes and fourth in the Prix Maurice de Gheest.

[3] In August 2013, the filly was consigned by the Ballyphilip Stud to the Doncaster Premier Yearling sale where she was bought for £41,000 by Peter & Ross Doyle Bloodstock.

After racing in third place she took the lead inside the final furlong and accelerated clear to win by almost four lengths from the Brocklesby Stakes winner Cock of the North.

In July at Newbury Racecourse, Tiggy Wiggy started the 5/2 favourite against twenty-three opponents in the Weatherby's Super Sprint, a race for two-year-olds old at public auction, with the weights being determined by the sale price.

Carrying top weight of 127 pounds, she led from the start and quickened away from her rivals approaching the final furlong to win by six lengths from Haxby.

On 27 September, Tiggy Wiggy moved up to Group One level for the first time for the Cheveley Park Stakes at Newmarket Racecourse and started the 6/4 favourite against eight opponents.

After being in touch with the leaders in the early stages she weakened in the last quarter mile and was eased down by Hughes to finish sixteenth of the eighteen runners behind Muhaarar.

[13] In the International Classification she was ranked the equal-best two-year-old filly to race in Europe, level with Found and two pounds behind the top colt Belardo.
