Casey Jarvis will take a one-shot lead into the final round of the DP World Tour after an adventurous bogey-free 64. The 21-year-old was three shots back after completing his second round early in the morning but was in a share of the lead at the turn after making four birdies on the front nine. Jarvis won the Euram Bank Open last season but now holds the 54-hole lead at an Asian Swing event for the first time.
