Joe Collings-Wells hit an unbeaten 125 to help Hambledon boost their Southern Electric Premier League division one survival hopes with a six-wicket win at Hook & Newnham Basics.
After Roscoe Thattil (four for 18) helped restrict the hosts to 216 for nine, Collings-Wells exploited a superb batting track to earn his team a vital win.
Burridge, meanwhile, slipped to a surprise 22-run defeat at relegation-battling Andover despite the efforts of all-rounder Geoff Dods.
Dods took four for 68 runs as the home side were limited to 220 for nine and then top-scored with 74 in his side’s reply.
Derek Kenway (33) and Rick Ankers (32) provided the only support, though, as they fell short of the target on 198.
Sarisbury Athletic took advantage of the slip-up to take over at the top with a thumping 101-run success over Rowledge.
David Banks celebrated his first game back from a ban with an outstanding 93 to put his team back in charge.
‘Burridge slipping up has opened the door for us again,’ said Banks.
‘We must make sure we win our next two games so that we can go into our final game, against Burridge, with the advantage.
‘If we can do that then it will make it tough for them.’
United Services’ division two survival hopes suffered a huge blow with a six-wicket defeat by Calmore Sports at Burnaby Road.
Portsmouth remain in pole position in division three courtesy of a hard-fought 36-run derby triumph over Portsmouth & Southsea.
Rob Jones (52), Vikram Dawson (43), Farshan Jemildar (43) and Liam Duffield (35) all played their part in helping the home club reach 248 for seven.
Matt Benfield led the P&S challenge (51) but Jemildar (three for 35) made sure they fell short.
Second-placed Havant II showed they are not giving up the chase, though, with an 81-run win over Fair Oak – as Chris Wade’s devastating spell of six for 11 proved crucial.
