David Evans enjoyed a excellent afternoon at Ffos Las after saddling a near 438-1 four-timer.
The Welsh trainer got the fixture off to the perfect start as 9-4 favourite Give Em A Clump made every yard of the running in the Bet With Peter Sutton Bookmakers On Course Nursery under Kieran Shoemark, with stablemate Kheleyf's Girl chasing him home to give the stable a one-two.
Yorbelucky (4-1) then initiated a treble for jockey Fran Berry by upsetting 1-2 favourite Christopher Wood in the EBF Novice Stakes, before Topmeup (5-1) landed the Peterson Family Supporting The NSPCC Cymru/Wales Handicap.
The final Evans runner on the card was Fastnet Spin in the BBI Group Supporting Childline Wales Fillies' Handicap and the 7-2 joint-favourite stayed on well for Berry to score by a length and a quarter.
"I've had worse days," said Evans. "I thought they all had chances if they went on the ground, which was pretty horrendous.
"I did think there was a chance I could have four winners, but I'd probably end up with none. I've had a lot of seconds recently."
The Abergavenny-based handler was particularly pleased with the performance of Yorbelucky, adding: "He's a really nice horse and he'll be an even better horse next year.
"He's the first horse Roger Brookhouse (owner) has had with me. Roger owns the stallion (Yorgunnabelucky), who is a full-brother to Shamardal, and this is first winner, so it's worked out great."
The most valuable event of the day was the £12,000 Army Cadets Wales Supporting NSPCC Schools Service Handicap.
Peter Bowen's useful jumper Rolling Maul (7-4) was bidding to make it four from four on the level, but finished a well-beaten fourth as Andrew Balding's 6-4 favourite Look My Way sauntered to a 22-length success in the hands of David Probert.
Balding completed a double with even-money favourite Lorelina in the Irish Stallion Farms EBF Fillies' Handicap, with 7lb claimer William Cox doing the steering.
