Peter Lawrie could not have delivered the new ‘Green i’ satellite player monitoring system a better look-in on day one of the BMW PGA Championship at Wentworth.

Lawrie was never out of sight posting a six under par 66 to be tied with Scotland’s David Drysdale and one clear of three players including World No. 10 Justin Rose and big-hitting Spaniard Alvaro Quiros.

The Dubliner’s round included a fourth hole eagle and four birdies and his best ever West Course score..

‘Green i’ is a Finnish-designed satellite tracking system that monitors the exact whereabouts of all players.

It is being backed by Lawrie and his management team who have the GB & I marketing rights, and was launched this week at Wentworth.

“What better launch for ‘Green i’ than for me to be leading the tournament,” said Lawrie.

Green i is being trailled at Wentworth so that spectators can look at screens and know the exact and precise location of all 156 players competing in the flagship tour event.

However Lawrie was in a lot different mood starting out and revealing his nervousness to Belfast caddy, Brian Martin.

“I said to Brian going down the first, I have never been as nervous because I was playing so well, trying to put so much pressure on myself to get a score, playing the way I was in practice,” he said.

“Lucky enough, it has come off. I’ve shot 66 to be up on top of the leaderboard and hopefully I can stay there.”
