Round 4 play (4pts):
Dustin Johnson to beat Martin Laird -150 @ Stan James, BetFred, BetInternet and Boyle Sports [available generally]
Easy to back Johnson in this situation - in second place and three shots behind the leader rather than three shots in front of the field. He was in this situation in the PGA Championship and showed how much he has improved as a marquee player. For Laird, he won on the PGA Tour last year, but that was from off the pace and the only time that he has previously held the end-of-day lead in a PGA Tour was after the 1st round of the 2008 Wyndham Championship; he shot 74 the next day to drop to 61st. His interviewer summed it up yesterday - "Without being dramatic, tomorrow's is the biggest day in your professional career" - so while he may go to win from this position, I don't see him pulling away from the field.
