Thomas on a birdie spree

US PGA champion Justin Thomas ran off eight birdies at TPC Boston for a tournament-best 63, giving him a share of the lead with Australian Marc Leishman.

Leishman shot a 65 to join Thomas at 12-under.

Eight players were separated by three shots going into the final round this morning, including Jordan Spieth and Dustin Johnson, Paul Casey and Jon Rahm.

“I just felt I had total control of my game,” Thomas said.
