Aussie doubles duo Jordan Thompson and Matt Purcell are through to back-to-back grand slam deciders, and it could come with a life-changing pay day.

The pair defeated Americans Nathaniel Lammons and Jackson Withrow 6-4 7-6 (7-4) in the semi final of the US Open, earning a chance to redeem themselves after Wimbledon heartbreak.

Thompson and Purcell failed to convert two match points at the All England Club, losing to Henry Patten and Harri Heliovaara.

However, they could land a maiden title together after the win at Louis Armstrong Stadium.

“Unbelievable … that (Wimbledon) was a heartbreak so they would love to get another opportunity here to win a grand slam. They’ve been quite a pair, haven’t they?,” Jelena Dokic said on Nine’s coverage.

If the two are able to win the final, Thompson could earn a $1 million (AUD) pay day from his work at Flushing Meadows.

If the 30-year-old and Purcell win, they’ll split a $1.13m purse.
