The 18-year-old, who dominated Hunter Valley pacing in 2018-19 with 50 victories in his first full season, had just one winning treble before Monday's breakthrough success on the eight-race card.

He guided Miss Ciriello, Yourblueyescrying, Repartee, Misterfire and For The Bettor to wins in consecutive events.

"I thought I had a pretty good book going into it but you never expect to have days like them, so it was good to pull it off," Callaghan said.

The 1.5-metre win of Yourblueyescrying, trained by Chris Bourke, was a highlight for Callaghan.

The mare was bred and is owned by Dean Latter and his late wife Anne Bourke, who died in February when hit by a car while crossing a road at Heddon Greta.

Yourblueyescrying had not won since July 2018.

"That was a pretty special win," Callaghan said.

"Dean and the rest of the family were rapt with that and I was just lucky to be a part of a special win like that."

Callaghan started his winning streak with the Margot Lennox-trained Miss Ciriello.

"She's racing really well at the moment and when she gets into the lead or a forward position, she seems to really relish that," he said.

"Margot has her going really good at the moment and it was good to get a win on her."

Jack's father, Mark, trains Repartee and For The Bettor, while Misterfire, which hung on in a photo finish, is trained by Joe Clark.

"It was good to get a win for Joe, he's a mate of ours and he really enjoyed it," Jack said.

The Newcastle Herald's form guide liftout will be in Thursday's edition this week because of Good Friday.
