Marcus Harris and Will Pucovski broke the 30-year record held by Mark Waugh and Steve Waugh for the highest partnership in Sheffield Shield history as their monumental opening stand for Victoria extended to 486 on the third day against South Australia.

The pair resumed on 0 for 418 with Pucovski on 199. He reached his second double century off the first ball of the day as he and Harris moved briskly up the records charts.

Harris was dropped at slip by Callum Ferguson with the score on 436 and it was his cover drive which took the stand to 465, surpassing the Waugh-Waugh landmark which was made against Western Australia at the WACA in 1990-91.

As attention turned to the all-time first-class partnership lists and a 500-stand loomed, South Australia finally ended the stand when Harris gloved a short ball to the keeper.

They were just short of the first-class record for any wicket in Australia which is the 503 added by Aaron Finch and Ryan Carters against the New Zealand XI in 2015 during a game that was then abandoned due when the pitch became unsafe.

The highest first-class partnership in history is the 624 added by Kumar Sangakkara and Mahela Jayawardene against South Africa in 2006.

Pucovski, opening for the first time in first-class cricket, finished unbeaten on a career-best 255 when Victoria declared on 3 for 569.
