Local trainer Bill Prain will be happy to play the role of party pooper at Warwick Farm on Friday as Gai Waterhouse and Peter Snowden do battle for the Sydney trainers' premiership.

Waterhouse, with 83-1/2 wins, leads Snowden by 1-1/2 in the title race which concludes with the eight-race card in Sydney's west.

The unlucky Prince Of Capers runs in the Busby Handicap (1600m), one of the few races in which Snowden and Waterhouse both have runners.

Waterhouse is represented by Bermuda Bankroll while Snowden has Merovingian and Juveniles.

"I wouldn't want to upset Gai or Peter and wish them all the best but if I do upset them in this race I won't lose any sleep over it," Prain said.

"He's (Prince Of Capers) had about as much luck as a fly in a Mortein bottle.

"He missed out on some more luck with the barriers for this race and will start from the widest gate (16)."

Prince Of Capers was slowly away last time out at Randwick on July 11 when he ran fourth to Vintedge over 1600 metres.

A start earlier he jumped awkwardly and got a long way back before hitting the line strongly and making up a stack of ground to run a half-length second to Cheap Thrills at Randwick in a 1300-metre race.

That run came a couple of weeks after he jumped on terms from the widest alley, 12, in a 1400-metre event at Warwick Farm and led all the way to defeat Sherzando.

Chris Munce is booked to ride Prince Of Capers who has two wins and three seconds from his 12 starts.

"I'll leave the tactics up to Chris. But I'm pretty sure if the horse doesn't lead he'll be in the first two or three," Prain said.

"He was six lengths behind the second-last horse a couple of starts back and stormed home but he won't be that far back on Friday I promise you."

Prain is expecting plenty of speed early, especially from Bermuda Bankroll who led all the way at the same track over Friday's distance on July 14.

"My bloke's nothing flash but he's got plenty of speed and he'll have to get going fast early to have a chance, he'll have a go that's for sure," Prain said.
