The hosts outscored Old Laurentians by two tries to one but went down to a single-point defeat thanks to two long-range penalties from visiting stand-off Dan O’Brien.
The game kicked off in sunshine with a strong wind favouring the visitors but it was Old Leamingtonians who applied the early pressure.
However, they were thwarted by long clearance kicks from the visiting stand-off which took play far back into their territory.
A penalty from just inside OLs’ half was then converted to give Old Laurentians the lead against the run of play.
The visitors began to exert more attacking pressure and winger Troy Owen came inside to score under the posts.
Undeterred, the hosts continued to pressure Old Laurentians, who were using the wind to good effect to clear their lines.
Eventually, the pressure paid off when, following a series of pick and drives, prop Craig Ellis gathered from the back of a driving maul to cross for a well-earned try.
The conversion was wide.
Just before the interval, O’Brien slotted over a penalty from the half-way line to give Old Laurentians a 13-5 interval lead.
The second half was evenly contested with both sides having opportunities only to be thwarted by good defensive play.
It needed a piece of magic from Liam Wellings to break the visitors’ resistance. Setting out from inside his own half the outside-centre outstripped the cover defence and broke a number of tackles before touching down for the only try of the half.
Tom Eales’ conversion reduced the deficit to a point.
The final 15 minutes saw chances for both sides but Old Leamingtonians had to settle for a losing bonus point
