The Watersiders are within three points of the County Division One title - which they will surely clinch at St Cross Symondians on Saturday - while Hythe seconds go into their final match with Southampton Travellers top of County 4 West.
A 93-run win over Burridge II put Hythe within touching distance of the CD1 crown - Tom Gates (114) underpinning his side's 240-7 before the hosts were dismissed for 147.
With George Wilson taking 4-25, probable runners-up Parley were able to defend 179-8 against Hook & Nenham Basics II, who fell 20 runs short.
Fareham & Crofton's prospects of a top two finish disappeared with an untimely collapse, which saw them crash from 106-1 (Sam Stoddart 54) against Ryde, for whom Cam Mitchell took 5-21.
Ryde lost three early wickets, but skipper Stuart Robertson cracked a 17-four 89 not out to get them home without further loss.
Hursley Park leapt above Fareham into third place with a successful 250-run chase against St Cross Symondians III at The Quarters.
Charlie Harden hit an undefeated 111 for St Cross (248-4), who lost all four wickets to Rory Tennant (4-42), who dropped a belated reminder to past Hampshire junior rep team selectors.
Paul Marks (77) and Scott Hills (61) provided a launch pad for Lee Wateridge (37) and Tom Flynn (33) to finish the job.
Bedhampton are all but home and dry in County 2, but Sway are celebrating promotion after an 82-run win over Portsmouth II - Alex Hall cracking a superb 144.
RAM's hopes of the C3 North title all but disappeared with an untimely 37-run defeat at Michelmersh & Timsbury - a result which allowed Redlynch & Hale to take over top spot with one game left.
Whoever wins Saturday's Winton-Emsworth will be CD3 West champions.
Old Netley & Highfield have a firm grip on the County 3 South title after defeating Southampton Community, the overnight leaders, by 84 runs at Wide Lane.
