In Division Three, leaders Harrow Town remain top despite being held to a draw by struggling Ickenham.
Skipper Michael Jadunath (53), Abid Javed (66) and Theophile (53) led the way with the bat as Harrow posted 313 all out.
Ickenham, however, took a point after P Waller's stubborn 50 not out contributed to their 230 for 8 after 53 overs.
Division rivals Kenton suffered a set-back in their bid to catch the top two with a five-wicket defeat to Wycombe House. Kenton declared at 225 for 9 but Wycombe eased past the target with B Mayers (77) on top form.
Both Harrow Town's and Kenton's second XIs drew to keep their respective survival and promotion hopes alive.
Town claimed four points against Ickenham (187 for 8) with Mohammad smashing a classy unbeaten 123 in his side's 278 for 9 declared.
Kenton seconds, meanwhile, could not get out Winchmore Hill's last two batsmen as they reached 229 for 8 off 52 overs. Vinjihani was Kenton's star man, contributing 104 of his team's 269 all out score. The four points means Kenton are three shy of second-placed Finchley.
Joe Brandreth returned sublime figures of 6 for 9 for Harrow Town thirds but the batting attack let them down in a 123-run pasting at the hands of Brentham.
Imran Hamilton scored 109 of Brentham's 219 for 9, declared after 51 overs, before Harrow crumbled for just 60 in 30 overs.
Kenton's third team also ensured a winless weekend for the club, with a five wicket loss at Acton.
Bishan (66*), S Patel (59) and N Islam (52) helped Kenton to 261 for 7 in 50 overs but Acton reached the target inside 48.
