Staying at Goodwood, St Mark’s Basilica gained a first-crop standard-bearer when Diamond Necklace beat older mares in the Group 1 Nassau Stakes. In America, Tiz The Law, Willoughby's Dirt Sire of the Week, added another Grade 1 winner through Eunomia in the Grade 1 Clement L Hirsch Stakes. Tiz The Law gained an important credential, but the result doesn’t yet prove that his daughter belongs among the division’s strongest performers. Siyouni (#24 from #27 turf sire) gained a different form of reinforcement through Soreanga in the Group 1 Preis der Diana. The German homebred beat French Group 1 winner Lapotheose by 3½ lengths, extending the sire's influence through a Classic performance with international collateral substance.
