St Matthias produced one of their best performances of the season to beat high-flying Three Bridges III in the West Sussex League.
Mid-table Saints, who only had ten men and were missing opening bowler Robert Sherlock, were set an intimidating target by second-placed Bridges who closed on 228 all out.
John Gray hit 63 and Richard Jenner (50) batted well for the home side, Simon King took four wickets for St Matthias.
In reply, Niall Smith (43) and Steve Mander (67) gave Saints a good start and Paul Hornby hit the winning runs.
Skipper Colin Allen said: "Our away form has been excellent, we have won all our matches away but we can't win at home."
West Blatchington got their title challenge back on track by beating Palmers by two wickets.
Palmers were restricted to 148-9 as Jig Agnihotri took 4-30 and Narleen again bowled tightly, taking 2-14 in his ten overs.
Blatch got off to a flyer and were coasting at 105-1, with Stuart Warne making 39.
Palmers fought back and took eight wickets for just 25 runs before Robert Stickland saw Blatchington through with an unbeaten 36.
Stickland said: "I couldn't believe some of the shots our batsman were playing, they were trying to win it in one over."
Blatch host second-placed Crawley Eagles this weekend and the visitors must not lose to maintain their championship ambitions.
Eagles remain second following their 24-run win at home to Lancing Manor. Eagles batted first and were all out for 189, Tayub hit 69. In reply, Manor were dismissed for 37.

Ram scored 262-8 to leave the visitors shellshocked. Tarun hit 62 and Danny 36.
