Massive jump start by Lorenzo

Jorge Lorenzo's miserable start to the 2014 MotoGP season has continued in Austin with the double world champion making a massive jump start.

Lining up on the centre of the second row, in fifth, Lorenzo bolted as soon as the red lights were illuminated.

The Spaniard then paused, but was almost level with pole sitter Marc Marquez and appeared to decide he might as well go and accelerated again shortly before the red lights went out.

The Movistar Yamaha rider, who fell from the lead on the opening lap of round one in Qatar, was duly issued with a ride-through penalty.

While Lorenzo rejoined in last place, Marquez now leads Repsol Honda team-mate Dani Pedrosa, with Pramac Ducati's Andrea Iannone in third.

Aleix Espargaro and Valentino Rossi, starting either side of Lorenzo, appear to have been distracted by Lorenzo's start and plummeted to the lower end of the top ten by turn one.
