On 10 October he was ridden by Jim Crowley when he started at odds of 5/1 for a novice race (for horses with no more than two previous wins) over the same distance at Nottingham Racecourse and recorded his first victory as he took the lead approaching the final furlong and prevailed from Alfred Boucher and Swindler in a three-way photo-finish.

[7] Seventeen days later the colt was stepped up in class and distance to contest the Group 3 Horris Hill Stakes over seven furlongs at Newbury in which he was partnered by Martin Dwyer and went off the 33/1 outsider in a field of eight.

After tracking the leaders Mohaather went to the front approaching the final furlong and despite hanging right and then left in the closing stages won "readily" by three quarters of a length from Great Scot.

"[10] Two weeks later Hamdan Al Maktoum's racing manager Angus Gold announced that the colt had sustained an injury to his right foreleg and would be off the track until autumn.

[11] Mohaather eventually returned in the Group 1 Queen Elizabeth II Stakes over one mile on heavy ground at Ascot Racecourse on 19 October.

[12] The flat racing season in Britain and Ireland was disrupted by the COVID-19 outbreak and Mohaather did not make his reappearance until 16 June when he contested the Queen Anne Stakes which was run behind closed doors at Royal Ascot.

After racing in mid-division he took the lead approaching the final furlong and drew away from his opponents to win in "impressive" style by three and three quarter lengths from San Donato.

Mohaather settled behind the leaders as Circus Maximus set the pace from Vatican City but when the field bunched up early in the straight he appeared to be boxed in and unlikely to find room to race forcing Crowley to pullthe colt back to the rear and then switch to the left to make his challenge on the outside.

Mohaather made rapid progress in the final furlong, overtook Circus Maximus in the last strides and won "cosily" by three quarters of a length.
