Clotworthy started the day with a narrow win by Penumbra and Leith Innes in the first event, the Jorja's 6th Birthday 1600, then cheered on stablemate The Jungle Boy to win the fourth race, the River Rd Blast 2000 in the hands of Tony Ihaka.

The pressure was then on Krash to make a clean sweep on the day for Clotworthy in the fifth event, the Tamahere Punters 2000, and the seven-year-old came with a well-timed burst to win by a long neck from Acid Jazz, another trained at Byerley Park (by Ben Foote).

Sharing in the ownership of all three horses is Clotworthy's father, Kim, who was especially delighted by the win of Krash, the mount of Craig Grylls.

"It's been a huge day for the stable and a great day for Byerley Park, who has won four of the five races (the other winner from the track being Agamemnon)," said Kim Clotworthy.

"This win (by Krash) means so much to me.

"I said to Craig Grylls that I always wanted to put him on a winner for me.

"I rode against his grandfather, Johnny, over fences when I was an amateur, then he rode a winner for me.

"And Craig's father, Gary, rode Whoc for us and won a few on him.

"I wanted to have the three generations of the Grylls' family win for us and now it's happened."

The Clotworthy stable is enjoying a great innings with today's treble following on from a double recorded at Wanganui by Twelve Monkeys and Templar.

"Shaun has only got 12 to 16 horses in work and to win three out of three on a Premier day is a huge result," said Kim Clotworthy.

"It's never happened before."

Krash has now won four races and had been unlucky not to add to that winning tally.

"He's been a bit unlucky at times and he's a hard horse to beat if he's ridden cold like Craig rode him today," said Clotworthy.

"He was only two and a half lengths off Castle Heights at Christmas time and that's good form."

Krash is raced by Kim Clotworthy, Ray Trigg and Northland crayfisherman Ash Mitchell, while Clotworthy shares in the ownership of The Jungle Boy with Daniel and Elias Nakhle.

The Jungle Boy, a four-year-old son of Jungle Pocket, has now won twice from five starts.

Penumbra is raced by a syndicate and broke through for her first win today after three minor placings.
