Fresh off an incredible chase at The Open, Phil Mickelson is eyeing this weekend's US PGA Championship for his sixth career major.

Mickelson missed out on that elusive sixth major in cruel fashion earlier this month, beaten by Henrik Stenson's record scorecard at Royal Troon.

Though the Scottish wounds are still fresh, the 46-year-old Mickelson is putting his recent disappointment on the back burner.

"I think over time I'll look back and my disappointment will probably increase," Mickelson told reporters on Tuesday at Baltusrol Golf Club in Springfield, New Jersey.

"It's the first time in my career where I've played to that level in my career and not won a tournament.

"But because we do have big tournaments coming up and because I am playing well, I don't want to let another really good opportunity I have to play a PGA Championship at Baltusrol, a course I like while my game is sharp, and let the disappointment linger.

"The idea is just to get back and start playing at that level again and hopefully it will be enough this week."

Much like the situation he faced at Royal Troon, Mickelson last won the US PGA Championship the last time it was held at Baltusrol in 2005. Though the field of golfers has changed dramatically from that tournament over a decade ago, the course is largely the same.

Mickelson said it will be important to drive the ball straight, but not necessarily far, because the openness of the front of the greens allow for fair iron shots toward the pin - where things get a bit trickier.

"Putting is a challenge here because the greens have a lot of contours and they're not consistent contours," he said. "You can see multiple lines and one is correct. I think reading the greens will be the biggest challenge for most people out here."

Despite all the signs that point to another trophy in his case, Mickelson is not planning a victory lap just yet.

"Any time you enter a tournament with a result in mind you never play your best. What I want to do is play to that level I played to at the British Open and have to believe it will be enough this time if I'm able to duplicate that performance," he said.

"The plan is to just go play and trust that I'm hitting a lot of good shots, which I have been."

Mickelson tees off on Thursday morning alongside world number one Jason Day and Rory McIlroy.
