Friday, 26 May 2017 : Jamieson carded a five-under-par 67 to finish in a three-way tie for second behind Sweden’s Johan Carlsson.
Englishmen Ross Fisher and Graeme Storm are a stroke further back, alongside Bradley Dredge of Wales.
“We had the best of the conditions, not a breath of air, and the greens are so good this year,” said Jamieson, who was in the first group out at 07:00 BST.
Jamieson’s score was matched by Kiradech Aphibarnrat and Francesco Molinari, with Open champion Henrik Stenson and Ryder Cup star Thomas Pieters part of a nine-strong group on four under.
A round of 69 kept England’s Tyrell Hatton in touch, but two bogeys saw compatriot Justin Rose end on level par with Danny Willett, also of England.
Defending champion Chris Wood began his title defence with a level-par 72 that included three birdies and three bogeys, throwing his ball into the water after dropping a shot on the 18th.
“I couldn’t hit the hole from three feet,” said the Englishman. “I’m pretty disappointed and not in the best frame of mind now.”
