Jordan Spieth unconvinced of Open changes after back-nine struggles

World number three Jordan Spieth had mixed feelings about the changes to the course set-up after squandering a flying start to the third round of the Open Championship.

Spieth, who was one of a number of top players to make the cut on the mark of four over par, carded four birdies in his first seven holes at Royal Troon to get back to level par for the tournament.
