NORTON, Mass. (AP) – Brendon de Jonge described his opening round Friday at the Deutsche Bank Championship as coming out of nowhere. Jordan Spieth’s start – his third straight round over par – was becoming far too familiar for him.

De Jonge ran off seven birdies in calming conditions at the TPC Boston for a 6-under 65 that gave him a two-shot lead over nine players, including Rickie Fowler, Henrik Stenson and Luke Donald.

Jason Day, needing a victory to become No. 1 in the world for the first time, reached 5 under until two bogeys over his final five holes. He had a 68 and was right in the mix. Rory McIlroy, back at No. 1 and playing for only the second time since the U.S. Open because of an ankle injury, had a 70.

But Spieth was visibly irritated just an hour into his round after two poor irons shots set up bogeys, and his day never got much better as he shot 75.
