TEENAGE Morisset driver Jack Callaghan scored a winning double at Newcastle on a good night for his father's stable on Saturday.
Trainer Mark Callaghan won with Vega Star at Menangle and Kotiro at Newcastle, where his son, Jack, oversaw their team.
Jack gave the Geoff Dorn-trained favourite Mista Taptoe Lombo a comfortable run in the one-one before the nine-year-old gelding proved too good in the straight to win by 4.6 metres in race five.
Callaghan had more work to do on Kotiro ($5.50) in the next, sitting behind leader Breakntherules before getting out late to just beat him on the line.
At Menangle, Vega Star resumed from a six-month break with victory on a good night for the Hunter brigade.
Todd McCarthy took Vega Star to the front from gate six and he was never headed to win by a half-neck in a career-best time of 1:52:8.
Lovin Miss Daisy was a 1.8m second for Callaghan and McCarthy in the next, where Major Occasion clocked 1:51:6.
Also on the program, Kitchener trainer Michael Osborn and Maitland reinsman Dan Morgan combined to win with Exterminate, which ran a personal-best winning time of 1:53:7.
Keinbah trainer Roy Roots jnr finished the meeting with a victory as accomplished trotter Glenferrie Typhoon had his first win for the stable.
The nine-year-old, a winner of $527,999 in stakes, was having his first run back after finishing a distant last on debut for Roots jnr in December, after which he was stood down by stewards pending an electrocardiograph.
