CHON BURI, Thailand (AP) -- Four-time European Tour champion Alex Cejka of Germany shot an 8-under 64 Thursday to take a one-shot lead after the first round of the Thailand Golf Championship.
The 43-year-old Cejka rolled in his eighth birdie of the day on the 17th hole to take the sole lead from Justin Rose, who was already in the clubhouse after a bogey-free round.
Rose was tied for second at the Asian Tour event with Arnond Vongvanij of Thailand.
Cejka said "I hit the ball very well today," and that "I took a couple big chances and made birdies."
The fourth-ranked Rose picked up three birdies on the front nine before adding four more on the back at the Amata Spring Country Club.
Defending champion Charl Schwartzel was in a tie for sixth with Sergio Garcia and two others after a 68.
