William Lambert had been one of the great batsmen of the early nineteenth century — the first man to score two centuries in a first-class match (175 and 56 for Sussex against Epsom in 1817) and the principal professional partner of Squire Osbaldeston in single-wicket challenges. In the same 1817 season he was accused, on circumstantial evidence, of selling his wicket in an England v Nottingham match at Lord's. The MCC committee, under Lord Frederick Beauclerk's influence, banned him from Lord's for life. The ban effectively ended his important-match career. He continued in club cricket — he was 38 when banned and went on playing into his fifties — but never again appeared at the highest level. His 1820s were spent at the Surrey village of Burstow, where he farmed; he died in 1851. The Lambert ban shaped the 1820s in two ways. First, his patron Osbaldeston resigned his MCC membership in 1818, partly in solidarity, and was himself blackballed; with Lambert and Osbaldeston gone, single-wicket cricket lost much of its lustre. Second, the precedent of a professional banned for life on circumstantial evidence — without any formal hearing or appeal — set the tone for MCC's relationship with the professionals through the 1820s and beyond. Match-fixing rumours continued to swirl around big-money matches in the early 1820s, but no further bans of comparable severity were imposed. Some later writers, including J.M. Kilburn, have argued that Lambert was treated unjustly and that the evidence against him was thin.
