It's a marathon, not a sprint to the finish line at the PGA Championship.
From Whistling Straits in Kohler, Wisconsin, Jason Day proved the theory true yet again with another consistent round of play on Saturday.
But he has this year's two-time major champion nipping at his heels, as Jordan Spieth is two strokes behind.
To view Sunday's live and updated scores, follow the leaderboard below.
Day has been progressively getting better during his PGA Championship. With a four under on Thursday, Day went five under on Friday and six under on Saturday to take first place outright entering the final round.
His eight birdies on Saturday was just further confirmation that he is playing some of the best golf of his career, as he looks primed to take home a championship, especially after his shot on 17, as shown by the PGA Tour:
Just don't be so quick to hand Day the trophy yet.
After sitting in a tie for 24th after the first round, Spieth has embarked on a two-day charge that puts him in Sunday's final pairing with Day.
Spieth used a magnificent back nine on Saturday, birdieing six of his final nine holes to make sure the golfing world was aware that he wasn't going away easily. And he sure has picked the right time to get hot, as ESPN Stats & Info takes a look at Spieth's recent run of play:
Branden Grace and Justin Rose sit a stroke behind Spieth and will need monster days in order to overcome either Day or Spieth.
Pressure makes even the most consistent golfers grip the club a little bit tighter. Luckily for those following the PGA Championship, those in the final pairing are playing some of the best golf of their careers. All it takes is one mistake or one brilliant shot to completely shift momentum, as Sunday will be pressure-packed.
