Kerrin McEvoy claimed his first winner for Gai Waterhouse when he got the best out of Common Objective in a driving finish to the $100,000 Lord Mayor's Cup at Rosehill.

The short neck victory over the John O'Shea-trained Music Review in Saturday's 2000m feature capped a great week for McEvoy, who ended the Rosehill meeting with a winning treble.

McEvoy claimed a breakthrough Group One win in his home state of South Australia on Sunday when he rode Kidnapped to victory in the South Australian Derby.

The leading rider was then successful on Monday in his appeal against a one-month suspension for his ride on Shakes at Randwick in March.

And on Tuesday, McEvoy's wife Cathy gave birth to the couple's second child, a baby boy named Jake Michael.

"This is my first winner for Gai and it's a bit of a buzz to get a winner in these colours," McEvoy said after the Lord Mayor's Cup, referring to the green and blue colours made famous by Waterhouse's father Tommy Smith.

Common Objective ($4.60), stepping up to the 2000m third-up from a spell, controlled the speed in front before he was made to fight doggedly in the straight as favourite Music Review ($2.80) came up on his inside.

The pair raced clear to fight out the finish but Common Objective proved a little too strong in the run to the line, with Vision And Power ($7) turning in a good performance with 61kg to be 1-3/4 lengths away third.

"My fella is just a real fighter and we knew he would run the trip," McEvoy said of Common Objective.

"He had a nice time of it, he was able to dictate in front and I think it suits this horse.

"He laid his ears back when (John) O'Shea's horse got to me and it was a good tough effort."

The Lord Mayor's Cup win was the middle leg of McEvoy's treble, with the Peter Snowden-trained Shannara and Skytrain his other winners.

Waterhouse was happy to back-up Common Objective in the Lord Mayor's Cup after he finished fifth to Snow Alert in the Rowley Mile (1600m) at Hawkesbury a week earlier.

She also revealed a deal to sell the five-year-old to race in Darwin was all but clinched earlier this year before a change in plans kept the gelding in Sydney.

Common Objective is likely to head towards the Listed McKell Cup (2400m) at Rosehill in a fortnight, with O'Shea also to go that way with Music Review.

Joe Pride was pleased with Vision And Power's third and confirmed he would press on with plans to send him to Brisbane for the winter carnival with the Group One Doomben Cup to be his next start.

"It was a nice return to form by him and he booked a trip north for three races up there," Pride said.
