The Longford Cup will now be worth $25,000, up from $20,000, and the other six races at the iconic New Year's Day meeting will go from $12,000 to $15,000.

The extra meeting will be at Spreyton on Monday January 11, giving the state three thoroughbred meetings in the space of six days.

Normally, that might be considered excessive, but there appears to be so many horses in work that it shouldn't an issue.

Current horse numbers were emphasised by the 148 nominations for Longford, of which only 58 will get a start due to field restrictions.

The restricted-class races are limited to eight starters and the Longford Cup 10.

Only six races were originally programmed and all had enough entries to be divided - some of them several times over.

However Tasracing said the lack of raceday stalls at the country venue meant it couldn't conduct any more than seven races.

The Longford Cup has a full field of 10, plus two emergencies, with Hobart Cup placegetter Glass Warrior heading the weights on 59kg.

Glass Warrior is trained on the track - a big advantage - by John Blacker who won his third Longford Cup last season with Triple Strip.

Only one of the 2020 runners, White Hawk, who finished seventh, is in Friday's field.

Other changes to the January calendar include the addition of three extra Tasbred bonus races. Full details of the new programs are on the Tasracing corporate site.

Tasmanian Jockeys Association boss Kevin Ring has officially advised his members that chief steward Scott Quill has been moved aside from thoroughbred duties.

Ring said he had been told that Quill wouldn't be in charge of any thoroughbred meetings until an inquiry into the Hobart track fiasco was completed.

He said he understood that Quill would continue to work at harness and greyhound meetings.

Ring also passed on the information to the Tasmanian Trainers Association.

The Office Of Racing Integrity has made no announcement but Ring said that Racing Minister Jane Howlett and Tasracing CEO Paul Eriksson were both aware of the move.

Ring said he did not agree with the decision as, of all the stewards in Tasmania, he regarded Quill the best qualified to be in charge of the summer carnival.

Tasracing has confirmed that the Scottsdale Cup meeting on Friday January 8 will be run at Carrick.

It had originally been transferred to Mowbray because Scottsdale couldn't meet COVID-19 restrictions.

However, Mowbray has now been allocated the thoroughbred meeting that was to have been held in Hobart the same day.

As a result, Carrick officials quickly put up their hand to host the Scottsdale Cup which looks a good fit for the country venue.

It's understood that the Carrick club will run the bar and kiosk, Scottsdale will do the race names and trophies and both clubs will supply volunteers for judging, timekeeping and track duties.

The changes all look positive - the thoroughbreds get to keep a Sky 1 slot that generates extra money (benefiting all three codes) and harness gets another meeting at its most popular venue.

A treble at Devonport on Tuesday night gave Gareth Rattray outright victory in the 2019-20 Tasmanian drivers' premiership.

Rattray started the meeting on 70 wins - one behind Rohan Hillier and Conor Crook.

A win on Tarleton Riley in the fifth race meant he could do no worse than share the title - as Hillier was finished for the night and Crook didn't drive at the meeting.

Another win in the second-last race of the season on Mach Charm gave Rattray the premiership all to himself then, for good measure, he won the last on Karalta Dazzler.

It was Rattray's 11th driving premiership.

He won 10 in row from 2006 to 2015.

Ben Yole won a record 189 races in the extended season to claim his fifth successive trainers' title. He also had 10 winners interstate.

Hannah Van Dongen was the leading female driver, Juanita McKenzie the leading female trainer and Taylor Ford the leading junior driver.
