Lap four crash from sixth place costs Jack big haul of points in round two.

Jack’s chances at a career-best MotoGP result have been thwarted by a crash on lap four of the Grand Prix of Argentina on Sunday afternoon.

The race, won by Honda’s Marc Marquez, was reduced to a 20-lap flag-to-flag battle after concerns about the durability of Michelin’s tyres following the delamination of a rear slick on the Ducati of Scott Redding in Saturday practice.

Starting from an equal career-best 15th on the grid, Jack made a lightning getaway at the Termas de Rio Hondo circuit on Sunday, gaining four spots in the first three corners before finishing lap one in 11th.

With riders cautious on a drying track after morning rain, Jack seized his chances to move up to seventh on the next lap, and then sensationally passed reigning world champion and series leader Jorge Lorenzo (Yamaha) for sixth on lap three.

Jack took off after Ducati pair Andrea Iannone and Andrea Dovizioso, but fell at Turn 3 coming onto the back straight on the next lap, a chance of the biggest points haul of his career frustratingly going begging.

It was little wonder Jack was despondent once he returned to the pits.

“The track was in good condition, and I gave it 100 per cent,” he said.

“I just pushed too hard in Turn 3 and lost the front. There’s not much to say about it.”

Despite the result, Jack showed over the weekend that the lingering effects of his ankle injury from the pre-season are beginning to fade, finishing Friday practice in a superb fourth place. He finished just four-hundredths of a second outside of making Q2 for the first time, Valentino Rossi squeezing him out of the top 10 after the four practice sessions, while he looked on track to advance from Q1 before a crash at the second-last corner on his final lap.

“The biggest thing for me to take away from the weekend is knowing where the limit is,” Jack said.

“Two crashes in qualifying and one in the race – OK, the pace is there but I need to find that limit more and not go over it, but that’s coming with more experience.”

After such a dramatic race in Argentina, there’s little time for the MotoGP paddock to catch its breath before heading to Austin in Texas for next week’s Red Bull Grand Prix of the Americas on Sunday April 10.
