The main Purebred Arabian race of the day was the Listed Abu Dhabi Championship, one of three 1600m races restricted to three-year-olds.
It was won comfortably by Mestor, posting his third course and distance victory of the season for Champion Trainer Ali Rashid Al Raihe and his stable jockey Royston Ffrench.
Again, the colt, owned by the Royal Cavalry Of Oman, made virtually every yard and Ffrench said: "He is a really nice young horse who hopefully has plenty of scope to continue progressing. From the moment he walked in the yard we have always liked him and he has now won three without being seriously challenged. It would be nice to think he is a horse with a future."
Racing opened with the Abu Dhabi Fillies' Classic which was turned into a procession by AF Al Hemah under Tadhg O'Shea.
Trained by Eric Lemartinel, she was having her second career start and O'Shea said: "I rode her first time and she was very green. Clearly she has learned a lot and won very nicely tonight."
O'Shea then doubled up in the Abu Dhabi Colts' Classic, partnering Okba to victory for Mohammed Ali Al Ketbi.
O'Shea added: "He has had to work a bit harder than the filly but is a nice horse and still learning."
Apprentice Salima Al Taleei opened her account for the season on Maram for trainer Mohammed Al Shamsi in the 1200m handicap.
The jockey said: "It is nice to get a winner on the board but it has taken a while this season."
Racing concluded with a 2200m maiden in which Nawasi Alkeer opened his account at the third time of asking for trainer Jameel Salman with Carlos Sanchez in the saddle.
