Waimea College are celebrating their first ever win over Shirley Boys' High School following Saturday's 24-6 Press Cup secondary schools rugby success in Christchurch.

Deferred from earlier in the round due to adverse weather conditions, Waimea appeared well primed for the contest, outscoring the home team by three tries to nil after leading 10-6 at the break.

Following the previous weekend's disappointing loss to Marlborough Boys' College, a result that effectively knocked them out of top eight contention, Waimea played with significantly more precision on Saturday to comprehensively stifle the bigger Shirley team's home ground advantage.

Waimea's forward pack outscrummaged their larger opposition and, with both territory and possession in their favour, were able to turn that superiority into points.

An early penalty success to No10 Luca Roden was nullified by two penalties to his oppositie number Jamayn Isaako as Shirley took an early 6-3 lead.

That was to be their only lead of the contest, however, as a converted try to fullback Fletcher Mathews just before the break helped push Waimea to their four-point halftime lead.

Centre Sean Clementson turned provider in the second half, scoring Waimea's remaining two tries on the back of excellent field position created by Roden's and Levi McPherson's astute kicking.

Clementson and Mathews were Waimea's main attacking threats while closer in, No8 Lucas Bateup frequently cut Shirley's attacks off at the source with a superb defensive display.

Lock Sam Liebezeit controlled the lineouts, disrupting a lot of Shirley ball while also providing plenty of clean possession for his own team.

Waimea College 24 (Sean Clementson 2, Fletcher Mathews tries, Luca Roden 3 cons, pen) Shirley BHS 6 (Jamayn Isaako 2 pens) Ht 10-6.
