With Richard Hills choosing to partner stable companion Menwaal, O'Shea was the beneficiary on the Gill Duffield-trained winner on whom he was always close to the pace. He said: "It was a decent race and he has stayed on nicely. Gill's horses are in great form."
The jockey also partnered the easiest winner of the night, Boss Professor in the concluding 1400m maiden, the only Thoroughbred race on the night. He is trained by Ali Rashid Al Raihe, still fresh from his Meydan Carnival double on Thursday evening.
Trainer Duffield was to complete a 2200m handicap double of her own but it was Ted Durcan in the saddle on Sharakka who won the night's penultimate event to deny Lemartinel's Barag.
Trainer Jaber Bittar was responsible for two of the 1600m maiden winners with debutants Mudallal Al Reef and Ferass winning under Pat Cosgrave and Jesus Rosales respectively.
The third such maiden, restricted to fillies and mares, was won by Wayne Smith on the Julio Peromingo-trained AF Sataah. All three look capable of building on these first wins.
