Ryhope CW ended their debut top-flight campaign on a high note, following a 4-2 home victory against Washington.
The Mechanics, too, could afford a smile after avoiding relegation, following third-bottom Guisborough Town’s defeat to champions South Shields.
Gary Pearson’s Ryhope have been renowned for entertaining goal-fests in home matches and Saturday’s six goals took the tally to 102 in 21 games.
Lee Chapman fired Ryhope in front midway through the first half against Washington, and Tom Bott doubled the advantage five minutes before half-time.
Washington grabbed a lifeline when Jake Pickard pulled one back on 42 minutes, but Ryhope responded with two goals in as many minutes, courtesy of Josh Home-Jackson and James Ellis, to finish the first half 4-1 to the good.
The Mechanics had the better of the second half but managed just a solitary reply, with Pickard converting an 82nd-minute penalty to cut the deficit to two goals.
But their safety was confirmed when the result came through from Guisborough, who went down gallantly in a 3-2 defeat to South Shields.
Former Sunderland youngster Jordan Blinco gave the Mariners a second-minute lead, but, in the 15th minute, Stephen Roberts flicked the ball home to equalise.
Long-serving Shields man Barrie Smith regained the visitors’ lead, latching onto a through ball and firing them in front again.
Carl Finnigan tapped home from close range to make it 3-1, although Louis Goldsack had the last word for Guisborough, heading home in stoppage time.
Shields’ travelling support boosted the crowd to 963.
Sunderland RCA enjoyed a great result at seventh-top Consett, winning 5-0.
The aim now will be to secure a top-10 finish by beating Penrith in tomorrow’s final game of the season at Meadow Park (7.45pm).
RCA will go into the game in good spirits. At Consett, Stephen Callen headed home a deserved opener on 32 minutes and he made it 2-0 in the 66th minute, running onto a through ball and slotting home with a classy strike from the corner of the box.
John Butler then took command of the game, ending up with a brilliant hat-trick.
His first goal came in the 78th minute. He struck again in the first minute of stoppage time, after beating the offside trap, then completed his treble from the penalty spot, after being fouled by Jake Stafford, two minutes later.
Relegated Chester-le-Street finished off with a 2-0 home defeat to Newcastle Benfield.

Ibby Hassan headed West in front on 17 minutes, but Shildon rallied to win it in the final eight minutes. Adam Burnicle fired home to equalise and, with three minutes remaining, Matty Robson converted a spot-kick winner.
West have announced ex-Shildon boss Gary Forrest as their new manager for next season, assisted by Stuart Niven, Paul Connor and Keith Finch.
Morpeth, with a game left at Newton Aycliffe tomorrow, are certain to be runners-up, following a 4-2 home victory over fifth-top Marske United.
