• Stephen Wong, the Dunedin owner, had his first win for 19 1/2 years when Graceandtemika was successful last night.
"It has been so long since I had a win that I had to ask someone where the winning post was," quipped Wong.
He joined the ownership of Graceandtemika three weeks ago with the lease of the 3yr-old filly in partnership with Matthew Kelly, Waikouaiti trainer Bruce Negus, Colleen Negus, her mother Nora O'Connell and niece Nora Bishop.
Wong had his previous win with Waysun Mood at Addington in 1991. Waysun Mood was a half-brother to Master Mood who won the New Zealand Cup, Auckland Cup, Miracle Mile and New Zealand Free-For-All in 1986 for Wong and his father, Frank, when trained by Kevin Williams.
• Dana Mac confirmed her liking for Forbury Park when successful last night. Her three wins have been on the track.
She is trained at Waimate by Polly Cleave who races her with husband, Bob and son David Kennedy. Dana Mac was driven by Lawrence McCormick who is hoping the win would gain him a place in the South Island team competing against a North Island team in a junior drivers series at Addington next month.
• I'm A Dazzler was claimed for $8000 last night by Brett Thomas, a junior driver.
Thomas is with the stable of Phil Burrows, who will train the 10yr-old winner of 10 races. I'm A Dazzler finished ninth last night is his first race for four months.
The race for claimers was won by Notenuffinmypocket at odds of 42-to-one. Notenuffinmypocket, a 7yr-old, had not won a race 16 months.
• The long-established Setarip syndicate won last night with King John. The Southland syndicate has King John and Olgoldnblack (two wins) in the Rakauhauka stable of Clark Barron. Olgoldnblack was spelled in April.
• Wotavugot was declared a late scatching from race 9 on the grounds of being denied a fair start.
The Moth has been retired and returned to lessor Neville Humphries, of Balclutha. The Caprock mare won three races for Kerry Dance and two when trained by Tony Grayling.
• The Forbury Park Trotting Club is in the process of setting up its own mobile starting gate operation.
The club rents the mobile gate from the Southland consortium at present with staff coming from that area.
"It is a cost saving move to have our own mobile gate and operate with our own personnel," Paul Knowles, the manager of the FPTC, said.
"We are staging 23 meetings a year and it is a big expense."
The club already has a mobile arm mounted on a vehicle used for trials. The vehicle is due for replacement.
• The Auckland Racing Club meeting scheduled for tomorrow week has been transferred from Ellerslie to Paeroa.
The decision was made in view of the heavy track at Ellerslie.
