South African Sean Dickson and Englishman Joe Denly shared a record 382-run partnership for Kent against Northamptonshire in a County Championship match at Beckenham on Tuesday.
The pair, who began batting on Monday afternoon, continued their second-wicket partnership on Tuesday as Dickson moved to an individual career-best score of 318, the second highest by a Kent batsman in the county's 175-year history.
Denly was eventually out for 182 while Dickson departed 26 short of the record for a game in the county, set by WG Grace for the MCC against Kent at Canterbury in 1876.
Johannesburg-born Dickson's score was the highest in the County Championship since Kevin Pietersen's 355 in May 2015. Kent's 701-7 was their second highest first-class total.
The previous record for a Kent partnership was 368 put on by Aravinda De Silva and Graham Cowdrey against Derbyshire in 1995.
