The money is coming hard and fast in Tattersall’s Cup 2019 betting for this weekend in Brisbane for the Danny O’Brien-trained three-year-old Vow And Declare to beat home the older stayers in the Tatt’s Tiara Day support act.

Due to run as Eagle Farm Race 6 at 2:15pm (AEST), the Group 3 $200,000 Lazy Yak Tattersall’s Cup (3000m) features a dozen gallopers with the handicap clash increased in distance this Queensland Winter Racing Carnival.

Getting in on the 54kg minimum and drawn well in barrier five with Glen Boss to ride, Declaration Of War gelding Vow And Declare is the well-backed favourite firming right in from $4.40 to $2.90 in the latest Tattersall’s Cup odds at Ladbrokes.com.au.

Last time out the progressive chestnut ran through the line when runner-up at a roughie’s price behind Mr Quickie in the Group 1 Queensland Derby (2400m) at the Eagle Farm track.

He is tipped to relish the rise in trip and drop in weight this Saturday, Vow And Declare looking to wind them up late with a big run in the open-age field.

Four other runners are also under double-figures in an open Tatt’s Cup betting market this season including Big Duke ($4.60) carrying the 60kg top weight.

Kris Lees’ veteran seven-year-old is down in grade for this and is a three-time Group 1 placegetter in some of the country’s biggest races.

Fourth in the 2017 Melbourne Cup over the two miles, Big Duke hasn’t won a race since way back in October that year so is out to break a notable winning drought.

That said, the son of Raven’s Pass is an honest galloper whose more recent form shows a Group 1 Tancred Stakes (2400m) second back in March and last start third from barrier 18 of 18 behind Sixties Groove in the Group 2 Brisbane Cup (2400m).

He will be eating up the 3000m here and cannot be discounted despite giving the kilos away.

The other top fancies are Lindsay Park’s Brisbane Cup fourth placegetter Sin To Win ($6.50) who has winning form up to 3200m and the Grahame Begg-trained O’Reilly mare Our Libretto ($7) – another Brisbane Cup graduate having run 4 lengths back for fifth – drawn in barriers eight and one respectively.

Our Libretto’s Victoria-based trainer Begg has no concerns about her first run over further than 2400m believing she will be well suited to the 3000m on Saturday.

“She doesn’t hit the bit in her races. She goes around very casually in her races so we don’t think going over a longer distance is going to worry her,” he told AAP this week.

“She won’t over-race, that’s for sure. She will just go around and give herself a chance.

“On face value her first two runs in Brisbane looked disappointing but we felt she had excuses.

“At Eagle Farm two starts ago [when ninth in the Premier’s Cup] there was a very big bias towards the inside and she was back and tried to come wide and got beaten about five lengths.

“We thought there was quite a bit of merit in her run and we thought she ran well in the Brisbane Cup.”

Other notable Tattersall’s Cup hopefuls include last Saturday’s Ipswich Cup runner-up Sampson ($11) dropping in weight and Ipswich Cup Day winner It Ain’t All Honey ($26) also on the quick turnaround.
