Towcestrians survived a nail-biting final few minutes to clinch a crucial 26-24 victory away at rivals Windsor.
The result makes Tows strong favourites to finish second and clinch the promotion play-off spot – they now lie seven points clear of Windsor with four games remaining.
Looking to make a quick start, Windsor scrum-half Rhys Davies, who was influential throughout, put his team on the front foot as the hosts took an early 3-0 lead.
Tows replied through their forwards, who drove a line out from the five-metre line with Fen Gallagher dotting down the first try of the afternoon, converted by James Falvey.
It was a frenetic and end-to-end affair with Towcestrians looking to make use of the wind, but instead an overthrow at a line-out saw the Windsor fly-half pick up and run at the Tows line before Davies dived over from a scrum for a half-time score of 10-7 to the hosts.
After the break, Tows took the game to Windsor and Favley’s quick-thinking paid dividends when his tap penalty led to a try for Matt Yuill.
Falvey again added the extras with an excellent kick and now came a period of attacking pressure from the visitors, with Falvey diving over from short range, shortly followed by a try for Tom George, who run from 30 yards after a blindside break from a scrum.
Tows seemed in control at 26-10 ahead, but back came the home side, who bombarded their opponents with scrum after scrum before eventually crashing over.
Now with their trails up, Windsor reduced the deficit further and set up a tense final few minutes when centre Patrick Birch’s converted try brought the gap to just two points.
A poor decision to kick to touch from Tows then allowed Windsor one final attack, but they spurned the chance to steal victory when a penalty from halfway sailed narrowly wide, much to the relief of Tows.
With no game this weekend, Towcestrians next play on March 21 when they host bottom side Bletchley.
