Greerton who sneaked into fourth place in the Williams Cup semifinals - have caused a major upset by beating defending champions Mt Maunganui.
The underdogs will fight out the Baywide championship next weekend against Otumoetai Cadets, who won a battle of attrition with Tauranga Boys College.
Greerton elected to bat first at Mount's Black Park HQ. The Greerton top order found a new resolve and Ben Williams stood up to everything the Mount bowlers threw at him and was rewarded with his team's top score of 81. Shane Wineti (31no) and Richie Earl (23no) produced a sterling partnership as Greerton reached 194/5 in their allotted overs.
Mt Maunganui were in early trouble, losing their top order relatively cheaply. Mount skipper Daniel Hill posted an unbeaten 62 runs, however three run outs saw them removed for 186 - just nine runs short of a berth in the Baywide final. Richie Earl effected two of the run outs.
Cadets, who are chasing their 10th Williams Cup in the last two decades, had a real battle with Tauranga Boys College at the Tauranga Domain. The Tauranga Boys bowlers won the early tussle with the Cadets three down for 55 runs before Mathew Drake (67) and skipper Jono Boult (62) produced a 122-run partnership.
