Henry Pyrgos hopes he has given Scotland head coach Vern Cotter a searing World Cup selection headache after his back-to-back scoring displays.

The Glasgow Warriors scrum-half skippered the Dark Blues against Ireland last week and got himself on the scoresheet in the 28-22 defeat in Dublin.

He then climbed off the bench to put the seal on the Scots' first win of 2015 with a late try against Italy in Turin as they brought a six-game run of defeats to an end with Saturday's 16-2 triumph.

Both those touchdowns came just weeks after he also scored in his club side's Guinness PRO12 final success over Munster in Belfast.

Cotter is certain to include Pyrgos as one of the three scrum-halves heading south when he names his final 31-man squad next week. However, he will have to climb over skipper Greig Laidlaw and Edinbugh's PRO12 young player of the year Sam Hidalgo-Clyne in the Scotland pecking order if he is to start when the team get their tournament under way against Japan on September 23.

Pyrgos said: "I think I've hit form at the right time. It's always nice to score for Scotland, it's an amazing feeling and especially when you go on to get the win. It will be one of those moments you look back on when you finish your career.

"I feel like I've had a good year. I had a few unfortunate injuries but I finished the season strongly with Glasgow, playing in a really good team.

"I've had a few opportunities to play with Scotland early in this warm-up series which has been great.

"Hopefully the kind of performances I've put in will only help my chances of playing at the World Cup. I'm desperate to be involved in the big games.

"It means a huge amount to me to play for Scotland but my position is really competitive so I know it will be tough. But I'm building each week and trying to improve on things and hopefully that will put pressure on the coaches to make those decisions."

While Laidlaw was leading the side out during their disastrous Six Nations campaign earlier this year - and with Hidalgo-Clyne his understudy off the bench - Pyrgos was back at Scotstoun helping Glasgow build up a head of steam which would eventually take them to their maiden title success.

However, he refused to let the fact he had been left out in the cold with the national team affect his confidence.

"Rugby is a such an up-and-down sport when you play it professionally," he explained. "You can't really worry about what is out of your control.

"It's great for Sam and Grieg, they both had really good seasons and they got their opportunity for Scotland and did well.

"During that time I just concentrated on myself and I was fortunate enough to be involved with Glasgow when we were going well. That took up my full focus.

"Now I'm back involved with the national team and it's amazing. Hopefully I can keep going well and then give the coaches a tough decision."
