Record-breaking Thomas builds bid lead
Justin Thomas broke the course record at Medinah Country Club on Saturday to move six shots clear at the BMW Championship on day three.
Japanese star Hideki Matsuyama had broken the course record in Illinois on Friday when carding a nine-under-par 63 but that record didn't last long as Thomas shot an 11-under-par 61 a day later.
The world number 10, who has not won since the 2018 WGC-Bridgestone Invitational, made eight birdies, two eagles and just one bogey during his superb round to move onto -21 for the tournament, a lead of six.
Sunday will be the 10th time the American has held or shared the 54-hole lead on the PGA TOUR - he has converted six of nine such leads into victories - and it will take a big effort from the chasing pack to overhaul the leader.
Reacting to his sensational round on Saturday, Thomas told the Golf Channel: "It's just one of those freaky days when you get in the zone. I hit the ball pretty unbelievable. It's not like I made any long putts.
"I hit it close to the hole and took advantage of some opportunities when I had them and got a couple of good breaks."
American duo Tony Finau and Patrick Cantlay share second on -15 while Slovakian Rory Sabbatini is a further shot back on -14.
Spaniard Jon Rahm has sole possession of fifth on -13, one stroke ahead of Lucas Glover, Brandt Snedeker and Corey Conners.
