Mendip capped a blockbuster Thursday night at Meydan for trainer Saeed bin Suroor, giving the Dubai native four wins from six Thoroughbred races on the program with a 1 1/4-length victory in Round 2 of the Maktoum Challenge.

Ridden to victory by Kieren Fallon, Mendip raced 10th of 11 during the early portion of the Group 2, $250,000 race, launching his winning move on the far turn about three furlongs from the finish. Mendip made steady progress racing wide into the home straight and continued on resolutely to score a fairly convincing victory over longshot Haatheq.

Black Caviar will make her first start at seven furlongs, and can extend her unbeaten streak to 18 races, in Saturday’s $428,000 C.F. Orr Stakes at Caulfield Racecourse in Australia.

A 6-year-old Black Caviar will be an overwhelming favorite as part of a field of eight. Black Caviar, who will be ridden by regular rider Luke Nolen, drew post 5. She opened as a 1-25 shot with one Australian betting firm earlier this week.

Two Mike de Kock-trained Dubai World Cup hopefuls, Master of Hounds and Bold Silvano, will see action on the Thursday program at Meydan, with Master of Hounds heading the field for the Group 2, $250,000 Al Maktoum Challenge Round 2, and Bold Silvano returning from a year-plus layoff in the Group 3, $200,000 Firebreak Stakes.

[bc_video_id:243416:]Gamilati’s last-to-first stretch move produced an impressive 5 1/2-length victory in the UAE 1000 Guineas on Friday at Meydan in Dubai.

Winner of the Guineas trial last month in her synthetic-surface debut, Gamilati moved significantly forward with her Friday performance. The filly she had beaten by 2 3/4 lengths in the trial, Alsindi, finished almost nine lengths behind Gamilati in Friday’s race, a listed stakes with a purse of $250,000.

Godolphin and trainer Mahmood al Zarooni have a firm grip on the UAE 1000 Guineas, the featured race on Friday night’s card at Meydan. Their A Team for the Guineas is Gamilati, the mount of Frankie Dettori, but the al Zarooni-trained Pimpernel might not be all that far behind Gamilati, the likely Guineas favorite.

Black Caviar extended her unbeaten streak to 17 races with an easy win in Friday’s Group 2 Australia Stakes at Moonee Valley Racecourse, her first start in 11 weeks.

Sent off at 1-20 with bookmakers, Black Caviar had an ideal trip to win the about six furlongs race by 4 1/4 lengths over pacesetter Zedi Knight. Ridden by regular rider Luke Nolen, Black Caviar stalked Zedi Knight and Doubtful Jack, circled those two with a three-wide move on the left-handed turn and pulled clear with little urging.

On turf and synthetic courses, Musir was unbeatable in Dubai in January.

Thursday, Musir won the $200,000 Al Rashidiya Stakes over about 1 1/8 miles on turf at Meydan Race Course, the beneficiary of an ideal trip under jockey Christophe Soumillon. On Jan. 12, Musir won the first round of the Maktoum Challenge on Meydan’s Tapeta surface.

Black Caviar, unbeaten in 16 races, resumes racing Friday following an 11-week break in the Group 2 Australia Stakes at Moonee Valley Racecourse, a race she won in 2010.

Trainer Peter Moody has two Group 1 stakes over about seven furlongs at Caulfield on Black Caviar’s schedule in February – the $416,000 C.F. Orr Stakes on Feb. 11 and the $520,000 Futurity Stakes on Feb. 25.
