SA’s Thriston Lawrence in final group shoot-out with Billy Horschel at Open Championship
Horschel and Lawrence go out in the final group on Sunday afternoon.
World No 1 Scottie Scheffler is just one shot further back at two under after battling to an even par round of 71.
A total of 12 players are within four shots of the lead for what promises to be a fascinating final round.
Overnight leader Shane Lowry had a day to forget as the 2019 champion crumbled in the sodden conditions to collapse from eight under par after seven holes to one under by the end of his round.
Horschel was one of the big movers in a round that had allowed for lower scoring earlier in the day before the wind and rain picked up.
Starting at two under, Horschel produced a sublime four-under 32 on the front nine thanks to birdies at four, six, seven and nine.
