Matt Launchbury totally dominated Marcham's innings against Cumnor in round one of the Bernard Tollett Oxfordshire Cup.
But his 122 not out in their 169-7 was not enough as Cumnor won by nine wickets.
Andrew Robertson (65no) and Graham Scott (57no) steered Cumnor to 173-1.
Also through are Kidlington, who reached 136-3 in their 20 overs against East Oxford, with Andrew Buckingham hitting 38 not out and Shabaz Ali remaining unbeaten on 37.
East Oxford made 124 in reply.
The rain-delayed first round should finally be completed this week.
EYNSHAM ended a 15-year drought by defeating West Midlands Police Veterans by six wickets.
The friendly fixture has been running for 35 years, but Eynsham hadn't won it since 1993.
West Midlands looked set for a decent score before Eynsham captain Kris Clark brought on 53-year-old John Wilson, who is only an occasional bowler.
Wilson proceded to take 4-18 in the Police's 119 all out before his 15-year-old godson Matty Lake helped Eynsham to victory with a flashy 30.
