Glenn Metcalfe bursts through to score

He expertly drew the last marker, Adrian Durston, before releasing Scotland utility back Glenn Metcalfe, who was left with a clear run to the line.

Graeme Kiddie missed the conversion, but made amends with a long-range penalty to give his side the lead.

Two minutes later Bridgend regained the initiative when Warlow clipped over his second drop-goal.

The Welsh defence seemed to be comfortably stemming the Glasgow tide, but they surrendered another touchdown in first-half stoppage time.

Wing Mike Bartlett did the initial damage with a dash down the middle.

The ball was taken on by Donnie MacFadyen and Lee Harrison before Gordon Simpson sent Andy Henderson over.

Graeme Kiddie's run is halted

Kiddie was left with his most difficult kick to date, but thumped it over from the touchline.

Slack tackling at the start of the second period allowed Lions star Dafydd James to power his way through for a Bridgend touchdown, goaled by Warlow.

Glasgow responded in positive fashion with a 40-metre dash by lock Jason White, which forced the Welshmen to concede a penalty in their own danger zone and Kiddie claimed back the lead.

Three minutes later, Kiddie was substituted by Calvin Howarth, making his injury-delayed debut after coming on loan from Edinburgh.

He made an immediate impression by calmly slotting a 35-metre penalty to secure the win.
