Star New South Wales stayer He Knows Uno returned to his brilliant best at Wentworth Park on Saturday night, claiming his heat of the Group 3 Tedesco’s Menswear Chairman’s Cup in a sizzling 42.09.

Having his first start since his indifferent performance in the final of the Group 1 National Distance Championship at Hobart recently, the Mick Patterson-trained greyhound put in a near perfect display, with only the mighty Miata going faster at Wentworth Park this year.

Taking the lead into the straight the first time, He Knows Uno (pictured) exploded away to dispose of his rivals by seven lengths, with Thrilling Frank finishing second in what was a blanket finish for the placings.

While he will start a deserved favourite from box four in Saturday night’s $25,000 to-the-winner final, a talented line-up of chasers are on deck to keep the star conveyance honest.

They include reigning Group 1 Sandown Cup winner Irma Bale, sensationally run down in her heat by Ron Bell’s Hot Buzzard in 42.30.

Looking all over a winner heading off the top turn, the Graeme Bate-prepared favourite began shortening stride from thereon, with Hot Buzzard charging late to win by a neck on the line at odds upwards of 30/1.

Irma Bale’s first section of 16.01 was absolutely airborne and if she can reproduce that effort in the final expect her to be mighty hard to beat from box seven.

The remaining heat was another heart-stopping affair, with the Frank Daros-trained Switch Up just getting the nod over Anne Foley’s Dusty Valley in 42.52.

With leader Dusty Valley free rolling out in front, Switch Up made a lunge along the inside right on the line, getting the decision by the narrowest of margins.

Both chasers have shown they are more than capable and with even luck in the final are well and truly up to making their presence felt.

Five runners broke the 30 second barrier over the sprint journey on the night’s racing, with Tasmanian sprinter Rob Pines posting the fastest time following his all-the-way 29.82 success.

Making his Wentworth Park debut for trainer Ted Medhurst, the National Sprint finalist looked most comfortable on the Wentworth Park surroundings, running a brisk 13.78 down the back before striding away for what was a comprehensive victory.

Well supported types Transcend Time (29.97) and Free Will (29.96) continued on their winning at Wentworth Park also, as did grand old stager Fancy Dean (29.84), who defeated a hot line-up to claim his 20th city success.

Box two snared five of the 10 races on the program, with trainer Norm Becroft backing up his Bankstown City Cup success with Lusina at Potts Park earlier in the afternoon with reserve runner Rumble Town taking out the final event in 30.25.
