McIlroy has had an up-and-down week at Caves Valley, from day-to-day and from hole-to-hole. After a 4-under 66 on Friday, he turned in a rollercoaster round of 71 on Saturday which features four birdies, three bogeys and a double bogey.

Robert MacIntyre entered the day with a four-shot lead and after two holes, that lead is just one. MacIntyre made bogey on the par-4 first and the par-3 second, dropping him back to 14 under, while World No. 1 Scottie Scheffler went birdie-par to get to 13 under.

With just two PGA Tour events left, the second FedExCup playoff tournament tees off Thursday in Maryland, as the BMW Championship brings together the top 50 golfers in the standings — and with them, plenty of intriguing storylines from the very first round.
