The 38-run win over Easton & Martyr Worthy was their fifth on the spin and gives them a slender one- point lead over Hythe & Dibden, who inched a 558-run thriller at Shrewton.
Fareham lost in-form pair Tom Kent and Sam Stoddart for ducks before Australian James Heiniger (68), Dan Wimble (44) and James Headen (42) secured a competitive 242-8.
Wimble (3-17) and Ben White (3-36) got into Easton’s top order before Ben Stanbrook (74) put Fareham under pressure. A tidy left-arm spell by Morgan Frost (2-31) reduced the visitors to 203 all out.
Hythe & Dibden narrowly defended 271 (Hakin Perusi 53) at Shrewton, who mounted a thrilling run chase, with Rich Barnett (60), Dan Bingley (49) and Will Harries (65) taking the Wiltshire side to 267-9 (Tom Richards 4-56) and within a boundary of a victory.
Beaten by Hythe the previous week, Ropley bounced back with skipper Rob Smith (82) pointing his side to 268 against Longparish, who were dismissed for 186.
One-time Southampton University skipper Jamie Richards returned to the Burridge scene – and dropped first team selectors a firm hint – by hitting 120 in his comeback match at OTs & Romsey.
His century paved the way to a Burridge total of 216-7, to which OTs could manage only 157 in reply (Wathen 71).
But the highest CD1 score was by Jack Middleton, pictured, who struck a career-best 154, including 27 boundaries, as St Cross Symondians III posted 293 at Andover, who have lost all five games.
Andy Sale (68) and Rob Liney (51) hit back for the Lions, who replied with 251-9.
Oli Green (4-7) had United Services reeling at 16-6 and eventually 89 all out after Parley had put 243 runs on the board.
Harry Medhurst (60), Harry McGhee (47) and Don Quincey (40) were to the fore as Bishops Waltham chased down a target score of 232 to give the visitors a four-wicket win at Hook & Newnham Basics.
It was their first win of the season. Teenager Jack Robson (72) and Kevin Light (70) shone for Hook.
A Rowledge total of 158 (Richard Fulham 36) proved too many for Alton II (79), Jack Powell taking 3-14.
