Green shoots clear as weak round costs Daly
Gavin Green secured a one-shot advantage at the Czech Masters on Friday as overnight co-leader John Daly dropped way off the pace.
Green and Daly were among four players to shoot impressive eight-under 64s on Thursday, but their fortunes were considerably more contrasting in the second round.
Even a double at the 16th and a bogey at the 17th could not derail Green as he carded a 68, that blip coming in the middle of a stretch of seven birdies in 10 holes.
Ryder Cup hopeful Thomas Pieters, another to share the lead after Thursday, remained in contention following a two-under round made up of four birdies and two bogeys.
The Belgian was one of four players two shots back in a tie for third, with Jeff Winther second after matching Green's four-under 68.
Matt Wallace, with a share of seventh, carded the best score of the day, shooting eight birdies for a 65.
It was a different story for Daly, who fell away after five bogeys in a three-over 75, including dropped shots on three consecutive holes from the 16th.
Daly ended the day in a tie for 36th.
