The Blacker-trained Mulley's Idol won at Geelong on Friday at the amazing odds of $51 and Magnasa strolled home at Spreyton on Sunday paying a best-tote dividend of $4.30 in a race where he and stablemate Settler's Stone appeared to be the only two winning chances.

Settler's Stone started $1.65 in the $20,000 Benchmark 83 Handicap even though he hadn't won for more than four years and is more noted as a stayer.

Magnasa closed at $2.70 in the tab.com.au fixed-odds market but paid $4.30 in NSW to give best-tote punters a nice bonus.

Blacker wasn't surprised that Settler's Stone couldn't match Magnasa's turn of foot over the 1650m and the favourite went down by more than six lengths with Brockton Punch another six lengths away third.

"They went quick enough up front in a smallish field to suit Magnasa down to the ground," the trainer said.

"He loves Devonport, it's his favourite track, and he's now won six or seven races over a mile.

"Settler's Stone is a more a grinder and he couldn't sprint ... they ran the last 600m in 34 seconds and it would take a real good horse to do that."

Mulley's Idol, ridden by apprentice Jack Hill, won a Benchmark 58 at Geelong after gaining a start as the second emergency.

Blacker said he had no idea how the gelding could start at 50-1.

"He shouldn't have been - his form was good over there and his form was good here," the trainer said.

"He ran a close second at Geelong three starts earlier then came home and won at Mowbray before finishing an unlucky fifth.

"It was a good result for everyone on Friday. We'll leave him over there now and he can have another run in a fortnight or so.

"He'll stay with Leon Corstens - he's settled in well and loves it over there."

Punters who took the short odds about Newhart ($1.40 to $1.33) in the Class 1 Handicap had little cause for concern.

The half brother and stablemate to smart sprinting mare Derasa sat back in the field before running way from his five rivals to score by almost three lengths.

Newhart was ridden by Craig Newitt who finished the meeting with a double to take his season's tally to 83 and, even though there are only nine meetings to go, he's a chance to become the first jockey in eight years to ride 100 Tasmanian winners in a season.

Brendon McCoull achieved the feat with 104 wins in the 2010-11 season after setting a state record with 109 wins five years earlier.

Adam Trinder took training honours landing a double with former mainlanders Thineisthekingdom and Glifi Nifin Arkis while Terry Evans (Smooth Pebbles $12 into $5.50) and Liandra Gray (Noosafy $9.50 into $5) kept a lot of punters happy.
