Irian puts his perfect 3-for-3 record on the line at Chantilly on Sunday in the $560,000 Prix Jean Prat, a Group 1 mile for 3-year-old colts. A son of Tertullian trained by Jens Hirschberger, Irian is coming off a 1 1/2-length victory in the Group 2 Mehl-Muhlens-Rennen, or German 2000 Guineas, and is capable of handling this step up in class. Stephane Pasquier picks up the ride.\nOiseau de Feu and Handsome Maestro will be dangerous after their one-two finish over the course and distance in the Group 3 Prix Paul de Moussac on June 7. Westphalia, third in both the French Derby and the French 2000 Guineas, will represent trainer Aidan O'Brien, while Lord Shanakill, a sharp third behind Sea the Stars in the 2000 Guineas, invades from England for Ken Burke.\nThe Group 3, $112,000 Prix Chloe at 1 1/8 miles for 3-year-old fillies includes two candidates for Arlington Park's Beverly D. Stakes. Denomination, trained by Criquette Head-Maarek, won the Group 3 Prix Vanteaux before failing in the French Oaks, while the Mikel Delzangles-trained Providanza is coming off a win in the listed one-mile Prix des Lilas.\n* At Hamburg on Sunday, Wiener Walzer can add to the reputation of his sire, Dynaformer, in the 1 1/2-mile, $700,000 German Derby. Like Irian trained by Hirschberger, he won the 1 3/8-mile, Group 2 Oppenheim-Union-Rennen on June 14 and is out of the Kingmambo mare Walzerkoenigin, a two-time Group 2 winner who also won the Prix Chloe and was second in Belmont's Flower Bowl. His main challenger will be the Peter Schiergen-trained Saphir, winner of the Group 3 Bavarian Classic.
