He was from the sixth crop of foals sired by Frankel, an undefeated racehorse whose other progeny have included Cracksman, Adayar, Soul Stirring and Hurricane Lane.
[5] On 17 September he was stepped up in class for the Haynes, Hanson and Clark Conditions Stakes over the same distance at Newbury Racecourse and finished second to the front-running Zechariah.
Ryan Moore took over from Hornby when Westover started the 8/11 favourite for the Listed Silver Tankard Stakes at Pontefract Racecourse in October.
He raced in mid-division before making steady progress in the last quarter mile but failed to overhaul the gelding Mr Professor and was beaten a neck into second place.
[6] On his first appearance as a three-year-old Westover contested the Group 3 bet365 Classic Trial over ten furlongs at Sandown on 22 April when he was ridden by Hornby and went off the 5/1 third choice in the betting behind Goldspur (winner of the Zetland Stakes) and the Aidan O'Brien-trained River Thames.
He was among the leaders from the start, gained the advantage from Goldspur inside the final furlong and held off a strong late challenge from Cash to win by a short head.
He was switched to the outside a furlong out and finished strongly to come home third of the seventeen runners behind Desert Crown and Hoo Ya Mal, beaten two and three quarter lengths by the winner.
[10] Westover raced in second place behind French Claim before taking the lead entering the straight and drew away from his opponents in the last quarter mile to win in "impressive" style by seven lengths from Piz Badile.
