(CNN) -- Spain's Ignacio Garrido and European Tour rookie Rhys Davies carded seven-under-par rounds of 65 to share the lead after Thursday's opening day of the Malaysian Open in Kuala Lumpur.
Garrido, who has two European Tour victories to his credit and was a member of Europe's winning Ryder Cup side in 1997, and 24-year-old Welshman Davies hold a one-shot lead after a hot and humid day.
"I am very pleased," 37-year-old Garrido told the official European Tour Web site. "I think to start with a 65 on any golf course is a great score.
"But for me to come here from Madrid, where I have spent the last couple of months playing in the snow, then it is a very good score."
Asian number one Thongchai Jaidee and South Korea's Kim Dae-hyun lead the chasing pack, while a group of four players are a further shot behind.
WGC-Accenture Match Play quarterfinalist Thongchai would have held the clubhouse lead, but two late bogeys ensured he shared second place alongside Kim -- who remarkably played the final five holes in five-under-par.
A total of 30 players will have to complete their first rounds on Friday after a thunderstorm brought a premature end to the day's play on Thursday.
