Jack Miller has become the first ever Australian to secure back-to-back wins in 125cc/Moto3 with a confident victory at the Grand Prix of the Americas.

He’s been touted as Australia’s next Casey Stoner – but on Monday morning Jack Miller achieved something the motorcycling champion never could.

The 19-year-old became the first ever Australian to take back-to-back wins in the 125 cylinder class with a triumph at Moto3’s Grand Prix of the Americas.

It came just three weeks after his breakthrough race victory at the season-opening round in Qatar.

“I’m stoked to have won, I led every lap,” the Queenslander said.

Starting from pole, Miller survived a series of challenges from second-placegetter Romano Fenati and Efren Vazquez on the last two laps to cross the line 0.069secs in front.

Miller now holds a commanding 18-point lead on the championship standings over Vazquez, with Fenati and Spain’s Alex Rins a further eight points back.

“It’s been a perfect weekend – pole position and a victory,” he said.

“I don’t think we could have asked for a better race. The KTM was running perfectly, with a setup that allowed us to conserve the tyres and have enough grip to push on the final two laps.

“I was made to fight through to the end, but it was really good. Achieving a second consecutive win is amazing.

“We must continue in this way, but progress with in each GP. This will be very important throughout the year.”

Stoner scored two wins while competing in 125cc – aboard Aprilia machinery in 2003 and with a KTM bike in Malaysia a year later.

But the two-time MotoGP world champion was never able to string together successive victories, nor win the entry-level title.

Australia’s last champion in the category was Tom Phillis, whose four grand prix wins in 1961 earnt him the 125cc title crown.

Shortly after switching to his new team for 2014, Red Bull Ajo KTM, Miller declared his intention to do something no other Australian had ever done: win all three world championship classes in Moto3, Moto2 and MotoGP.

Like Stoner, Miller started out in dirt track racing and was a national champion before switching to the road and heading to Europe and he has been on the rise ever since.

Motorcycling legend Mick Doohan last month predicted the gun teenager would be Australia’s next star in MotoGP, suggesting he might even skip Moto2 and head straight into the premier class next season.

Argentina’s Termas de Río Hondo Circuit hosts the next round of the Moto3 championship on April 27.
