MELBOURNE, Nov 22 (Reuters) - Adam Scott rued a horror third round that all but ended his hope of a third Australian Masters title and will head into next week's Australian Open spoiling for a fight against world number one Jordan Spieth.
Tour veteran Peter Senior celebrated a richly deserved two-stroke win at Huntingdale Golf Club on Sunday but the trophy was virtually gift-wrapped for former world number one Scott halfway through his second round.
The 2012 and 2013 champion had marched to a five-stroke lead after a bogey-free run of 27 holes, but from there it became a grind.
