Tech 3 Racing Team rider Bradley Smith admitted to being "disappointed" after finishing 18th in the Australian Moto2 Grand Prix at Phillip Island.
The race was won by Alex De Angelis with Germany's Stefan Bradl still leading the Championships standings.
Oxford-born Smith recently signed a deal to race in the MotoGP World Championship in 2013 and 2014.
"Obviously today was pretty disappointing and not what I hoped for," admitted Smith.
The Tech 3 rider mounted a strong challenge for the podium in the early stages of the 25-lap race and a brilliant start from seventh on the grid rocketed him into third on the second lap.
The 20-year-old, who will race for Monster Yamaha Tech 3 team when he switches to MotoGP, was briefly bumped back down to sixth but two fine passes on lap seven moved him back into fourth spot but his top-three attack ended a lap later.
Pushing hard to keep pressure on Di Meglio in third, he ran off the track and dropped back to 28th.
But Smith launched an impressive fightback and eventually finished 18th.
"I did exactly the same as I did every other lap going into the corner, but I think the bike was unsettled a little bit by the curbs and just went sideways," added Smith.
"I had to go straight and there was nothing that I could do. It is one of those moments that when they happen you just have to react as quickly as possible to keep control of the bike.
"I was fourth at the time and feeling really confident of getting a podium, so to be not even in the points is difficult to accept."
Smith continued: "At the moment we don't seem to be able to catch a break and we've had some bad luck.
"But that's racing and once again we have shown the potential of the bike and I hope to be battling for the podium in Sepang in a few days."
