It's Moving Day at Valhalla.
Saturday at the PGA Championship started with Xander Schauffele leading the field by a single stroke. He's led the entire way so far, which is something only five other golfers in the last 40 years has pulled off.
His lead, though, didn't last. Collin Morikawa quickly overtook him on the back nine, though the two both birdied the 18th to get to 15-under on the week. That gave them a one-shot lead over what's a very packed leaderboard.
Shane Lowry nearly set a new record, too. He carded a 9-under 62, which made him just the fifth player in major championship history to ever post that score in a round.
