First foal arrives for Classic-placed Overbury stallion
Transvaal Sky gave birth to a colt on Wednesday
Simon Nicholson's Avonbridge mare Transvaal Sky, a winner at two when in training with Tom Dascombe, foaled a chesnut colt on Wednesday.
"He's very like his sire and was up and sucking within an hour," said Sweeting. "He's a tidy, attractive, good-bodied colt and I'm really pleased with him."
A treble Group winner for Hamdan Al Maktoum and Dermot Weld, Mustajeeb raced from two to four, winning a 7f maiden at the Galway festival on his second start at two.
He had five starts at three, finishing third to Kingman in the Irish 2,000 Guineas, before winning the Group 3 Jersey Stakes at Royal Ascot. He was then second to Bow Creek in the Group 2 Boomerang Mile on Irish Champions' Weekend.
Mustajeeb returned at four, winning the Group 2 Greenlands Stakes at the Curragh by a length from Maarek.
Mustajeeb made a return trip to Newmarket on Thursday to take part again in the Thoroughbred Breeders' Association stallion parade at Tattersalls.
He is standing the upcoming breeding season at a fee of £4,000.
