Amid speculation about who will replace him as Darley's head trainer, Peter Snowden keeps going quietly about his business capping the week with four winners at Randwick.

Snowden will leave Sheikh Mohammed's operation after the autumn carnival to train in partnership with his son Paul who runs the Melbourne branch of Darley.

In the meantime he just wants to keep the winners coming and although he didn't win the two-year-old race on Saturday as he has for the past four weeks, Snowden produced the victorious Sinjoren, Solemn, Emblems and Miniature.

All were ridden by Kerrin McEvoy who made a flying visit to Hong Kong on Wednesday to claim the International Jockeys' Challenge.

"It's been a good day," Snowden said.

"The horses are going well and there is still plenty for them to do.

Sinjoren opened Snowden's account in the Alconex Fire (1550m) when stretched his winning sequence to four from his past four starts.

By Exceed And Excel out of the late Antwerp, Sinjoren is a half-brother to Viscount, Australia's champion colt of 2000-01 and 2001-02.

He was unplaced at his first two starts and even after winning his next four, Snowden said the colt still had a bit to learn.

"He is getting better each time and growing in confidence," Snowden said.

"He will be fully tested in the autumn."

Stakes targets are a little closer for Solemn and Emblems, winners over 1800 and 1150 metres respectively.

"Solemn will step up to 2000 metres in the Summer Cup on Boxing Day," Snowden said.

"Emblems will be nominated for the Razor Sharp next week but I'm not sure whether he will back up.

"The idea was to run last week but he drew barrier 16 so we took him out.

"We might have to wait until the Takeover Target Stakes at Gosford next month.

"He had four weeks between runs going into today so it won't worry him."

Three-year-old filly Miniature showed her class when she stepped out of her age group to win the 1300m benchmark 80.

Snowden said the win against the older horses proved her class and she would be put away with the autumn in mind.

Darley was denied a fifth winner when Messene, trained by Snowden's former boss John Hawkes and his sons Michael and Wayne, beat Babel in the final race.
