Wallsend have upset defending champions Hamilton-Wickham courtesy of an impressive all-round display from skipper Nathan Price.
The hosts reeled in the 151 runs required just three wickets down and with 18.4 overs left on day two of the two-day first-grade fixture at Wallsend Oval.
Price scored 52 not out and combined with Ben Herring (55) for a second-wicket stand of 90 before the Tigers reached the winning target in 33.2 overs.
Earlier and Hamwicks resumed at 0-19, following a rain-affected 6.5 overs on day one a week before, with Price (2-36) striking twice to remove Pumas captain Josh Trappel (1) and Dave Stevenson (2) in quick succession at the top of the order.
Rhys Hanlon rallied batting at No.5 and made 68 for the visitors but Hamwicks were dismissed for 150 in 44.1 overs.
This result sees Wallsend (26 points) jump the title holders (24) into fifth on the competition ladder.
Elsewhere on Saturday and Newcastle City (160) remain the only unbeaten side after six rounds, accounting for the Sea Dragons (125) by 35 runs at University Oval.
The Sabres stay second on the overall standings with 34 points alongside fellow first-innings winners Wests (3-216) and Charlestown (4(dec)-155), downing Toronto (215) and Belmont (63, 8-193) respectively.
