Happy Wednesdays were back and the "King of the Valley" Caspar Fownes was never going to let rain dampen his spirits as the championship leader grabbed a cup race win at his favourite track with Jaeger Bomb.

After Sunday's daytime return to racing at the city track after a five-month hiatus, Wednesday night's fixture was the first night-time meeting since June.

And while the bursts if intermittent but heavy rain throughout the evening may have cleared the Beer Garden, Fownes said the wet conditions helped Jaeger Bomb produce his best.

"That rain came just in time for him," Fownes said of the first downpour, which arrived before race five and continued until the following race, the Community Chest Cup.

"His last win came when there was some give in the ground, so maybe that helps him a bit."

Barrier one certainly helped, too, with Zac Purton driving the five-year-old out of the gates to sit in the box seat.

"Those were my instructions - get that leader's back," the trainer said after his 15th victory of the season.

The leader of the jockeys' championship, Joao Moreira, continued his astonishing early season form with another double, with wins on Smart Guy and Verdane. The double gives the Brazilian 20 wins from the nine meetings he has ridden so far.

Smart Guy's trainer Peter Ho Leung said once his horse had put a good run on the board, it was simply a case of booking the star rider.

"We just wanted Joao and planned around when we could get him," Ho said. "Drawing gate one was a bonus."

Even though it took Verdane 17 runs to break through for his first victory for trainer John Moore, he has now won two from three this term. "And he might not be done yet," he said. "He is versatile, and the great thing with him going into Class Three with a light weight is that Joao can still ride him."

Few trainers are better at setting a horse for a particular race than David Hall, and the Australian sensed an early season opportunity with Medallist. The six-year-old had dropped four points after going winless in 10 runs last term, and won the Wayfoong Centenary Bowl handicap.

"We gave him a very good prep for this race," said Hall.

Despite gaining some favour from gate one under Nash Rawiller, Hall said the horse was adaptable enough to win again this season. "That drop certainly helped him. He was struggling under some big weights last season, but he goes at both tracks and he can get a bit further too," Hall said.

Almond Lee pulled off a quinella with Ocean Roar (Ben So Tik-hung) beating Ambitious Glory (Alex Lai Hoi-wing) in a Class Four, saying the only result that could have topped the stable one-two would have been a dead heat. "That way I would have got two winners," Lee said.

"I did it once before in 2008. I thought the second horse would be the winner in the run, as he had the easier run, but he will get his chance when we can get him back to the dirt."

Keith Yeung Ming-lun helped trainer Andreas Schutz pull off the biggest upset of the night when he led all the way on Trillion Treasure - but the jockey was slapped with a careless riding charge for stacking the field up dangerously in front, after crossing from gate 11.

Howard Cheng Yue-tin was also given three days for careless riding for his all the way victory on Apollo Cavalier. The careless riding ban will be served concurrently with his long-running and handling ban, unless the jockey appeals his suspension on Thursday.
