Glasgow edged a tight contest with Scarlets 19-11 at Firhill, holding their nerve as Dan Parks' haul of 14 points proved decisive.

The Scotland fly-half compiled his tally thanks to three second half penalties and a drop goal, in addition to his conversion from Rob Dewey's first half try.

Scarlets held a narrow half-time advantage thanks to a try from full-back Daniel Evans, but they were unable to take full advantage.

The first 20 minutes were notable only for two penalty misses apiece by Parks and Scarlets' Rhys Priestland, as defences cancelled each other out until a Parks break opened things up and off his pass, Kelly Brown was held inches short.

In the 31st minute an excellent Parks pass put Dewey in for the opening try in the right hand corner, Stortoni having been held on the left for Glasgow to move the ball through Chris Cusiter and Al Kellock for the wing to grab his first Magners League try for Glasgow.

Parks slotted the conversion and Glasgow continued to dominate until a superb short off-load by centre Jon Davies put full-back Daniel through a hole in the home defence to race away from 45 yards.

Priestland missed the conversion but as the clock wound down on the break, Glasgow indiscipline gave Priestland the chance to make amends and his first successful kick took Scarlets in at half-time 8-7 ahead.

The Warriors Thom Evans was hauled down inches short by fellow Scot Sean Lamont shortly after the interval but Parkes restored the hosts lead when Scarlets were penalised in front of their posts - only for Priestland take the visitors back in front by a point with a 45-yard penalty.

The home side were next on the scoreboard when Parks dropped a goal and the Warriors started to get the edge in what had been a very even contest and with 12 minutes to go.

Parks brought his tally to 11 points with his second penalty and he put the game beyond Scarlets with his third in the 79th minute, which denied the visitors a bonus point.
