It looked more like an exhibition than three Group 1 races on Sunday at Sha Tin, where heavy favorites made short work of the competition and Golden Sixty made some history.   Golden Sixty became the first three-time winner of the $2.55 Champions Mile while winning his ninth Group 1 contest, a Hong Kong record. Victory boosted his career earnings to $18,844,782, more than any horse ever.   At age 7, Golden Sixty remains the best horse in Hong Kong, a position he’s now held for three racing seasons. In February, running a 2,000-meter distance farther than ideal, he beat Romantic Warrior, who on Sunday crushed his rivals in the $3.18 million Queen Elizabeth II Stakes. Golden Sixty’s career mark stands at an eye-popping 25-2-1 from 29 starts. But at this point, we probably never will see Golden Sixty race outside Hong Kong, testing his limits abroad against international competition. A trip to Dubai this spring was considered and rejected, as have been nascent plans of traveling to Japan. Golden Sixty also had been mentioned as a possible runner Sunday in the QE II, where Romantic Warrior would have offered far more resistance than anyone in the Champions Mile.   :: Hong Kong: Free PPs, picks, analysis, replays, and live streaming The 7-year-old gelding’s connections have made it clear they prefer racking up easy wins to truly testing their champion, which is fine; owners get to decide how a horse is campaigned. But at the same time, there was a sense of inevitability to Golden Sixty’s latest triumph. And what really was proved by a 1 1/2-length victory at level weights over Beauty Joy, a Group 3 winner who has lost all seven of his races this Hong Kong season? Consistency of performance and excellence over time only go so far when it comes to a horse as good as Golden Sixty, whose trainer, Francis Lui, made post-race comments suggesting this might have been the gelding’s final start this season, his next goal a fourth start in the Hong Kong Mile next December.   Jockey Vincent Ho finally figured out this season that Golden Sixty need not be wrangled to the back of a field, forced to fly home and snatch victory on the wire, as was the case in many of his best tallies. Golden Sixty has done just fine taking a more forward position, and in the Champions Mile, Ho encouraged his mount to get into a pace-tracking position right out of the gate.  Caught between the two leaders most of the race’s one turn, Golden Sixty forged to the front at the 300-meter mark and won eased up the final few strides. Bred in Australia, the Hong Kong superstar is by Medaglia d’Oro out of Gaudeamus, by Distorted Humor, but neither he nor even Romantic Warrior was the sharpest Group 1 winner on this day.   Heavily favored Lucky Sweynesse did what was expected in the $2.55 million Champions Sprint Prize, but his 3 1/4-length victory in the 1,200-meter race was especially eye-catching. Pressing the pace under Zac Purton, Lucky Sweynesse went 21.86 for the 400 meters between the 600-meter and 200-meter marks, totally overwhelming the competition. Already an obvious winner, Lucky Sweynesse breezed home with a final 200 in 11.59 on the way to his fifth win in a row, third in Group 1 competition. Just a 4-year-old, Lucky Sweynesse might still have room to improve, and already the New Zealand-bred is excellent. Trained by Manfred Man, Lucky Sweynesse is by Sweynesse, a Lnhro stallion, and out of Madonna Mia, by Red Clubs, a son of Red Ransom.   “I feel like we’re going to see a better horse again next season,” Purton said. “The sky is the limit at the moment.”     Romantic Warrior left no doubt in the QE II, stalking a slow pace before moving to the leaders before turning into the homestretch and hitting the front with 300 meters to run. Jockey James McDonald stood up in his stirrups and celebrated with 20 meters to the finish, so easy was this win over the Japanese filly Prognosis. Trained by Danny Shum, Romantic Warrior, now 10-2-0 from 13 starts, is a 5-year-old Ireland-bred by Acclamation out of Folk Melody, by Street Cry. His next target is the 2,400-meter Champions and Chater Cup on May 28. :: Want to learn more about handicapping and wagering? Check out DRF's Handicapping 101 and Wagering 101 pages.
