OXFORD moved back to the top of the Division 2 table after a nine-run win over Oxfordshire rivals Thame Town, who slip to second.
It sees Oxford eight points clear with just three matches to play, with third-placed Harefield another four back.
After winning the toss the hosts made a steady start, but started to accelerate when Jamie Perkin and Muhammad Ayub got going.
Robert Craze was unbeaten on 44 at the close as Oxford set
199-6 off their 50 overs.
After a stand of 54 for the first wicket between Olliver Ebbsworth-Burland and Michael Beard, Thame lost wickets at regular intervals.
Devane Warner, batting at No 8, held the innings together with an unbeaten 53 off just 46 balls, but they were unable to keep up with the required rate and closed on 190-9.
Oxford Downs are still looking over their shoulder at the wrong end of the league after an eight-wicket defeat against Chesham in a rain-affected match.
Just 36 overs were possible in the Downs innings, with Tom Costley their top-scorer with 37 in their 135-8.
Despite taking two quick wickets, an unbroken stand of 108 between Andy Goddard (56no) and Robin Pritchard (48no) saw Chesham pass their target after 26 overs.
It means Downs are just 17 points clear of the relegation zone.
Meanwhile, Horspath are hovering over the Division 1 relegation trapdoor following a seven-wicket drubbing on the Duckworth-Lewis-Stern method at High Wycombe.
With Tring Park snatching a dramatic one-wicket win off the last ball at fellow strugglers Slough, Horspath are now 30 points adrift of safety at the foot of the table.
Having been put in to bat on a freshly-cut pitch following Friday’s heavy rain, Horspath collapsed to 29-5.
Tom Cosford smashed a whirlwind 55 off 30 balls with eight fours and three sixes, sharing in a rain-interrupted sixth-wicket stand of 61 with Mark Skelton (26).
But after they were parted, Horspath crashed to 128 all out, with Tom Hampton (4-36) the chief destroyer.
With DLS coming into effect, Wycombe were set a revised target of 127, which they eased to off 25 overs with Lloyd Paternott (37no) seeing them home after Conrad Louth made 34 as Liam Manley took 2-32.
At the other end of the table, Banbury moved second after a 32-run victory over Datchet, who had started the day as nearest rivals to Henley.
Lloyd Sabin (43) and Joe White (35) set the tone with an 88-run partnership for the opening wicket as Banbury reached 180-7 off 39 overs in a rain-affected match.
Joe Thomas then took 3-18 off eight overs before Charlie Hill claimed the final three wickets to finish with 3-12 off just three overs as Datchet were all out for 148.
Aston Rowant lost by two wickets in their clash against Finchampstead.
Tom Condon (68) and Hayden Rossouw (53no) starred with the bat as Rowant made 228-8 off 43 overs.
However, Adam Dewes then struck 95 and Edward Oliver hit 59 as Finchampstead edged to their target.
Rowant stay fourth despite the defeat.
