Barnes angled her mount wide at that point and was joined by race favourite Lord Darci with the pair settling down to a torrid home straight battle settled in favour of Summer Festival by a nose at the finish line.
Marsh, who leaves for a ten-day American holiday on Sunday night, was delighted with the results from the day.
"That is very exciting as I've been pretty desperate to get to that $3 million mark this season," he said.
"I was pretty edgy after the races at Rotorua were called off on Saturday as I thought we had several excellent chances and we only had the two runners in today.
"As it turns out they have both won and we've managed to get to where we wanted."
Marsh was quick to pay tribute to the horse who was sent to him by owner Paul Chow, who races him under his TM Racing banner along with a couple of his Hong Kong friends.
"Paul sent him to me and he has proven to be a wonderful old horse," Marsh said.
"He has really settled in well and has got better as he has gone along.
"He's not really a true heavy track galloper and I think when he rolled out at the 600m he was doing it himself, as he was probably looking for better ground.
"I did like his chances today as he was down to a very competitive weight with just the 54kgs.
"The way he has won it, we'd be silly not to have a crack at the Winter Cup (Gr.3, 1600m) at Riccarton in a fortnight.
"I will have a chat with his owners, but we might just pay the late nomination for the race as it looks as though the field might drop away a little and he could be in with a real shout."
Summer Festival is a former European galloper who spent the early part of is career in Italy where he won six of his nine starts including the 2018 Gr.2 Italian Derby (2200m) before being sold to Hong Kong where he failed to win but was placed in five of his 21 starts.
The seven-year-old son of Poet's Voice then headed to Marsh's stable in 2021 where he has now won twice to take his career tally to eight wins from 48 starts and over $924,000 in prizemoney. – NZ Racing Desk
