Thorp Arch and Boston Spa collapsed to a heavy 10-wicket loss at promotion-chasing Londesborough Park on Saturday.
The York Senior League Division Two basement side crashed from 44-0 to 95 all out as Park outlined their supremacy.
Stand-in skipper Andrew Griffiths (35) topscored but fellow opener Matthew Bentley (21) was the only other to make double figures.
The TABS attack failed to break Park’s opening stand as James Hanley (65) and John Williamson (26) capped the victory.
Tadcaster Magnet slipped down two places to sixth as their weakened team found Bolton Percy too strong.
With captain Phil Smith and stalwart Paul Clark missing from the top of the order, Magnet struggled for early runs, especially against the economical Andrew Brewster (2-10).
Number five Karl Buxton hit 41 and Jon Hill added 27 but they found little support as Magnet were ousted for 138.
Oliver Baxter grabbed the two Percy openers cheaply but Joe White’s 46 not out eased fourth-placed Percy past the total with five wickets remaining.
Magnet welcome Malton & Old Malton on Saturday. TABS visit Hornsea.
