Pieters takes one-shot lead at Firestone
Rory McIlroy had his best friend on the bag and his best start on American soil in 18 months. For Jordan Spieth, it was more of the same with two long putts and another comment filled with bravado directed at his caddie. Both of them opened with a 3-under 67 at the Bridgestone Invitational, leaving them two shots behind Thomas Pieters of Belgium. Pieters, playing only for the sixth time since he challenged briefly at the Masters this year, holed a 30-foot birdie putt on his final hole at Firestone to finish a day of good scoring with a one-shot lead over Russell Knox. Adam Hadwin of Abbotsford, B.C., is three shots back after a 68 while Mackenzie Hughes of Dundas, Ont., struggled to a 74.
