Italy's Francesco Molinari shot a 7-under 65 and took a 2-stroke lead on Thursday after the first round of the PGA Championship at Wentworth.
"You know, around here it's a great place, it's obviously a flagship event, so it's, you know a great start, but unfortunately nothing more than that, you don't get the trophy on the first day, so I need to, you know, keep my head down and do the same tomorrow and Saturday and Sunday and see if that is going to be enough."
Defending champion Rory McIlroy fired a 1-under 71, leaving him six shots behind Molinari.
Elsewhere,
Jordan Spieth, Ryu Ishikawa, Boo Weekley and Kevin Na all shot a six-under-par 64 to share the opening round lead at the Crowne Plaza Invitational at Colonial Country Club in Texas.
