Filed away in the department of "Where Did That Come From" is Nimble Nimbus’s win in the third race on May 11 at Happy Valley Racecourse.   A solid if unspectacular participant in Class 4 handicaps from the start of his Hong Kong career last season, Nimble Nimbus jumped up and won at that class level by a whopping five lengths. The gelding got a great inside trip and raced over a yielding course, but that might not have entirely accounted for the breakthrough. Trainer Ricky Yiu had been tinkering throughout the season with Nimble Nimbus’s equipment, adding a crossed noseband, then cheek pieces, but taking both things off on race day April 16 while adding a visor and a tongue tie. Nimble Nimbus didn’t take to Sha Tin dirt in that start, but perhaps it was no coincidence his big win came in his first run over the Happy Valley grass course with his new equipment package.   :: Hong Kong: Free PPs, picks, analysis, replays, and live streaming Hong Kong bettors will have to consider all of that in the last of nine races on Wednesday at Happy Valley, where Nimble Nimbus, his rating up 10 points, tries Class 3 competition for the first time. He’s one of 10 horses in a race for horses rated 80-60 and carded for 1,650 meters. The nightcap is one of two races run under those same conditions, the other being race 6. Race 8 is another Class 3, this one over 1,200 meters. The card starts at 6:45 a.m. Eastern. Live video and wagering are available at DRFBets.com.  Nimble Nimbus has a good draw in post 5 and rain in the local forecast won’t disappoint his connections. Drawn one stall inside him is the race’s other last-start winner, Win Win Fighter, who won a Happy Valley Class 4 at this distance May 18 by 1 3/4 lengths. He carries 117 pounds, one fewer than Nimble Nimbus, with Maldives the 133-pound highweight.   Maldives won a Class 3 while carrying 122 pounds to end his 2020-21 Hong Kong season, but, shouldering higher weights throughout his campaign, he has gone winless from nine starts this season. He does have four second-place finishes and two thirds this term, but post 9 doesn’t help Maldives on Wednesday.   En Pointe has a better draw, post 6, a better jockey, Zac Purton, and carries less weight, 127 pounds, than does Maldives, and he figures to attract support making his Happy Valley debut. En Pointe already has put together a successful campaign with a record of 7-3-0-3 and a Class 3 Sha Tin win under 122 pounds. En Pointe hasn’t raced past 1,400 meters but ought to be able to get 1,650 with Happy Valley’s shorter homestretch.  * Beauty Joy was a popular odds-on winner of the Group 3 Lion Rock Trophy Handicap on Sunday at Sha Tin. Purton rode the winner, a 5-year-old Australian son of Sebring, for trainer Tony Cruz in this 1,600-meter contest. Beauty Joy was a vet scratch on March 27 but otherwise has gone 6-4-1-1 this Hong Kong season. He carried 121 pounds, nine fewer than the race’s top-weighted horses while getting seven pounds from second choice Excellent Proposal, who rallied mildly to finish fifth.
