Lap three fall costs Jack dearly after brilliant Misano qualifying.

An early-race crash has cost Jack the chance to capitalise on his best-ever MotoGP dry-weather qualifying, the Australian finishing 18th in the San Marino Grand Prix at Misano on Sunday.

After a brilliant last-gasp lap in final practice saw Jack qualify directly into Q2, the Alma Pramac Ducati rider qualified a stunning second on Saturday, just behind fellow Ducati rider and pole-sitter Jorge Lorenzo.

Come Sunday, Jack retained second place as the 26-bike field, bolstered in numbers by two wildcards, streamed into Turn 1. Lorenzo’s teammate Andrea Dovizioso passed Jack at Turn 10 on the first lap, and he was then passed by Marc Marquez (Honda) a lap later, the world championship leader putting a hard move on Jack into Turn 14.

It was at Turn 14 when Jack’s chance of a strong points haul ended on lap three, as he low-sided at the slow right-hander and fell to the back of the field before re-mounting.

Jack fought as best he could for the remainder of the race, and picked off several riders to get from 25th to 18th at the end of the 27-lap distance, finishing 50.5 seconds behind race-winner Dovizioso.

“It’s a shame,” Jack said after the race.

“We did a good job over the weekend and the race pace was good. I was convinced that I could be with the leaders, but I made a mistake.”

Jack now falls to 13th place overall with 61 points ahead of the next race, at Aragon in Spain on September 23.
