<p>There's a guy battling leg pain and a 50-year-old man in Sunday's final pairing at the PGA Championship.</p>.<p>Brooks Koepka, coming off right knee surgery in March, hopes he can fight through pain and fatigue long enough to win a fifth major title and deny Phil Mickelson's attempt at a historic victory.</p>.<p>Koepka fired a two-under-par 70 to stand on six-under 210 after Saturday's third round at windy Kiawah Island, but a closing bogey cost him a share of the lead with Mickelson, who could become golf's oldest major winner.</p>.<p>"If I strike it anything like I did the last three days, I'll have a chance," Koepka said.</p>.<p>The leader of the under-50 flight is happy his knee hasn't shown any signs of weakness as it had before he arrived at the difficult Ocean Course.</p>.<p>"I've not had that once this week. Very pleased," Koepka said Saturday. "I think the strength has increased.</p>.<p>"I don't know if it was just a little tired, but I've kind of toned back the workouts a little bit, especially this week, just because I know what I've got to do."</p>.<p>The 13th-ranked American knew he would get a workout over the sand dunes and unlevel areas of the coastal course, the longest layout in major history at 7,876 yards,</p>.<p>"You're walking on sand a little bit, playing a lot of golf," he said. "Just toned it back a hair but made sure I'm still doing the important things in the rehab."</p>.<p>Koepka, the 2018 and 2019 PGA champion, seeks his third title in four years.</p>.<p>Not since Tom Watson won the 1980, 1982 and 1983 British Opens has a player won the same major three times in four years.</p>.<p>Koepka, who still makes somewhat of an awkward stance while lining up putts due to knee issues, says the event feels like any other major, even though his challenge is unusual.</p>.<p>"It just feels good, feels normal. It's what you practice for. I'm right where I want to be, and we'll see how tomorrow goes," he said.</p>.<p>"Just be within three of the lead going into the back nine and you've got a chance."</p>.<p>Koepka was upset at his putting, saying the course seemed faster than the practice putting area.</p>.<p>"That was the worst putting performance I've ever had," he said. "Can't get much worse. I thought 70 was about the highest I could have shot today. I left a lot out there.</p>.<p>"From inside 10 feet, I'm usually banging it in the back of the cup."</p>.<p>Koepka is playing in the final pairing as well, so he can keep an eye on that 50-year-old guy.</p>.<p>"At least I can see what Phil is doing and then I don't have to turn back and look and see what he's up to," Koepka said. "And everybody will be in front of me so I know what I've got to do."</p>
