Ross Fisher said he was pleased with his first round of the 98th PGA Championship where he finished on four under par

Ross Fisher feels that there are "a lot of chances" for the players on the Baltusrol course - if they can drive the ball well.

The Englishman had an impressive first round at the 98th PGA Championship, reaching the clubhouse four under par after hitting five birdies in a round of 66 on Thursday.

"I played really solid," he told Sky Sports. "I kept it on the fairway pretty much all day - from memory, maybe the 18th was one of the few fairways I missed.

"So I was in a good spot and able to lay it up, definitely if you drive it well around here you can give yourself a lot of chances.

"But having said that, the greens are quite undulating and they're in some tricky spots so you really need to put the ball in position off the tee to allow yourself to attack these flags."

Ross Fisher made five birdies in his round of 66

Five of the last six major winners have been first-time champions and Fisher believes that the quality is such that nobody can be ruled out.

"It would be nice to make it six out of seven, wouldn't it?" he added. "The standard across the board now is getting - the variety of good golfers is amazing. It feels like anyone can turn up on any given way, pick it up and win.

"I'm coming here believing my game is good enough to win. I've got off to a great start, but I'm not going to sit back on that. There's still a long, long way to go."

Fisher's fellow Englishman Andy Sullivan also enjoyed a productive opening round, finishing a shot back on three under.

Sullivan's 67 included four birdies on the front nine, five in total, and he was thrilled with his showing in sweltering conditions.

"I'm buzzing with that start," he said. "I've been playing really well leading up to the tournament, so it's just nice to keep the form and momentum going.

"It was a great atmosphere out there, the fans were making loads of noise and it was nice to be playing in the group behind Rory (McIlroy), Jason (Day) and Phil (Mickelson), because you could get a good view of the crowds.

"It was a bit of a struggle at times in the heat, especially down the stretch there, so I'm happy to get finished and enjoy some nice air conditioning.

"It was seriously hot and humid even first thing this morning, so I was seriously melting out there. But I'd take this over the cold and wet we had at The Open any day, so I won't complain."

Meanwhile, Chris Wood expressed his relief after going round in 69. The 28-year-old old was forced to retire after just 12 holes at The Open with a neck injury but came through unscathed in New Jersey.

"It was a huge relief to be able to play pain-free after three and a half weeks of not being able to move my neck," the BMW PGA Championship winner said.

"The longest shot I'd hit before this week was a 100-yard pitch on Sunday so when I arrived, I still didn't know whether or not I'd be able to hit a driver, which was a bit worrying.

"It was so bad at The Open; I know I played 12 holes but maybe I should count it as six because every swing was a half swing and I was carrying my driver 190 yards."

Paul Casey finished under par despite two double bogeys on the front nine

Lee Westwood and Paul Casey also shot one under rounds of 69 to stay in contention, with the former aided by an eagle three on the 18th.

Casey, meanwhile, shot an impressive 33 on the back nine but was hindered by two double bogeys - at the first and the fifth.
