Mosgiel midfielder Eder Franchini was in superb form in midfield, demonstrating his ability to tame the ball and hit early passes to set up his forwards.
The South American added Chilean cream on the cake with a well taken goal on the half hour.
Earlier, Franchini slid a perfect pass to winger Regan Coldicott, who showed direct pace to get to the byline and set up Rahan Ali to score with a precise shot that ignited double celebrations for the goal and Rahan's birthday.
In a bizarre start, the game might have been 1-1 after two minutes, as clear chances were spurned by both sides.
There were typical Tim McLennan runs up the wing for Technical, and Scots striker Sam French might have scored twice, but he underhit towards an open goal, and the ball was cleared off Mosgiel's line by a recovering defender, then a later decent effort that hit the net was ruled out as being offside by linesman Francois Cuccurullo.
The Dutch-Italian official was also on hand to confirm American referee Calvin Berg's decision to red-card former Mosgiel favourite Michael Abbott, now playing for Technical, and the volatile defender headed for a 35th-minute shower.
Another former Mosgiel player was keeper Zane Green in the Technical goal since Tom Batty was not available.
But second-half attacks had Green twice picking the ball from his net as Franchini hit a sweet return pass for Riley Anderton to score, then hard-working Connor Neill got his reward with the last goal.
Not normally given to animated delight, coach Andrew Brook beamed and said: "That's the best Mosgiel have played for a long time, and I also really appreciate our defence and keeper Liam Whittaker keeping a clean sheet''.
At Sunneyvale, Darren Hart's University side was expected to steamroll Green Island, but a spirited performance by coach Richard Kerr-Bell's youngsters did better than keep the students at bay.
The terrible playing surface sabotaged Varsity's over-elaborate play and, with pace to spare, Green Island played early ball forward and might have got on the scoresheet.
Two obstacles were a splendid match by pony-tailed centreback Cory Glover, who was named his side's man of the match, and the efforts of goalkeeper Charlie Morris who was quick off his line and safe in the air.
Midfielder Chris Kessell had a top match and scored the Varsity goal that stood alone for most of the match, until a 90th-minute superb strike by Ewan Bakker finally beat Island keeper Stewart Catto to produce a slightly flattering 2-0 scoreline.
The win hoisted University into third place on the FPL table.
Green Island coach Richard Kerr-Bell praised his young side's continuing improvement.
"We held them for most of the match and had several good breaks that went close to scoring,'' he said.
A late transfer to Tonga Park from Ellis Park, made rally drivers out of many Roslyn supporters, but on the day Caversham was in control for most of the match and won 3-0.
Seamus Ryder featured with two goals, the second a superb free kick, and Sam Collier robbed a defender to slot Caversham's third goal.
The home side never relinquished its grip on the game and remains top of the FPL.
Roslyn lost defender Tyrrell Barringer-Tairi on a double yellow card with 15 minutes to go, and perversely went on to play better football when a man short. Coach Colin Thom was pleased with how his side got better.
"We were a bit gun-shy at the start, but improved and had some very good performances especially keeper Tom Stevens who played on, despite suffering a dislocated finger,'' he said.
