Mastery, by Darley stallion Sulamani, landed his second classic of the season when running out a game winner of the St Leger at Doncaster.
Settled in third behind the pacemaker Von Jawlensky and Godolphin's other runner, and eventual second Kite Wood, he took up the running inside the final furlong to score by three-quarters of a length.
Mastery (white cap, left of picture) had already won the Derby Italiano on his first start for Godolphin this season, having previously been under the care of Mark Johnston. This was his third win in an eight-race career earning prize-money of over £750,000.
Bred by Darley, he is out of the winning Diesis mare Moyesii and a half-brother to Kirklees (Jade Robbery), who landed the G1 Premio Gran Criterium as a juvenile and G2 York Stakes this season.
Also at Doncaster on Saturday, Poet's Voice became Dubawi's second G2 winner in as many days when he landed the Champagne Stakes.
Sent to the front straight from the stalls, and although fairly keen early on, he never saw another rival running out a three-quarter length victor. This was his second victory from four starts and he holds G1 entries in the Middle Park Stakes, Dewhurst Stakes and Racing Post Trophy later this season.
Poet's Voice is a Darley homebred out of the Chief's Crown mare Bright Tiara, the dam of Japanese Group One runner-up Gold Tiara, by Dubawi's grandsire Seeking The Gold.
Dubawi is currently the leading freshman stallion in Europe with 22 individual winners, including yesterday's G2 Flying Childers Stakes winner Sand Vixen.
Cape Cross, Europe's leading stallion by win prize-money, enjoyed another successful day when his admirable son Mac Love won the G3 Select Stakes at Goodwood and his daughter Valletta scored at Listed level in the Grand Prix Inter Regional des 3 Ans at La Teste. Mac Love was recording his tenth career victory and third at G3 level in 2009 after being successful in the Diomed Stakes and Sovereign Stakes.
The other Listed event on the La Teste card, the Grand Prix du Sud-Ouest fell to the King's Best colt Not Just Swing, who won by two-lengths, with four further lengths back to the third. This was his sixth win (three of those at Stakes level) from 16 career starts.
At Chester on Saturday, Doyen sired his first ever winner when Kumbeshwar made all the running to win by half-a-length in their seven-furlong Maiden.
Owned and bred by G E Amey, he is out of the winning Lahib mare Camp Fire and from the family of Irish 2,000 Guineas winner Flash Of Steel.
