The Mufhasa colours were again to the fore at Hastings where a relative of the two-time New Zealand Horse of the Year continued the perfect start he has made to his career.
Among Mufhasa's 10 Group One victories were Makfi Challenge Stakes and Windsor Park Plate successes on the Hawke's Bay course, which on Saturday was the stage for Bostonian to show he had inherited a good measure of the family ability.
By Jimmy Choux out of a half-sister to Mufhasa, the Tony Pike-trained youngster was a debut winner at Avondale last month and he was just as impressive when claiming the Fasttrack Insurance Juvenile.
"He's a very laid-back horse with a great temperament for a two-year-old," said Pike, who prepares Bostonian for David Archer.
"He's only going to improve again from here. He's going to make a nice Guineas horse in the spring.
"We'll get him home and then decide whether we press on for another run or put him out, He's going to be a very progressive three-year-old up to a mile and possibly further."
Bostonian crossed from the outside gate to a handy spot one off the fence before rider Leith Innes peeled three wide on the turn.
They took control 200 metres from home and were untested to cross the line a length and a half clear of Mofara.
"I gave him one backhander and away he went," Innes said "He's a true professional and he's got a good future that's for sure."
Pacemaker Gilhoolie was a further two lengths back in third ahead of Lincoln Hills, who had a dream run but found little in the straight.
