PGA Tour: At Caves Valley Golf Club, Rory McIlroy, Jon Rahm, and Sam Burns are on eight under par, with Sergio Garcia one shot down and FedExCup leader Tony Finau three shots back.
After a low-scoring opening round at the BMW Championship, Rory McIlroy and world No. 1 Jon Rahm are in a three-way tie for the lead.
At Caves Valley Golf Club in Baltimore, Maryland, the European Ryder Cup teammates scored eight-under 64s to join Sam Burns at the top of the leaderboard, with Sergio Garcia a shot back in fourth.
Abraham Ancer is level for fifth place with Patrick Cantlay after making six birdies in a seven-hole stretch on his back nine, while FedExCup leader Tony Finau is among a large group of players on five under.
McIlroy started with a close-range birdie at the first, then missed a six-footer and missed the par-five second, before converting from 12 feet at the third and completing a two-putt birdie at the driveable fifth.
The four-time major champion sank a 30-footer at the seventh to help finish out a front-nine 32, then added shots at the 10th and 12th, only to fall three shots behind after bogeying the par-three next.
After an unbelievable three-wood with his approach into the par-five 16th, McIlroy scored a 10-foot birdie at the 15th and holed from a similar distance for eagle at the next, two pars wrapped up a blemish-free back nine.
Rahm missed an eight-foot birdie attempt at the first but followed it up with a two-putt gain at the par-five second and three straight birdies from the fourth with a 10-footer at the eighth to finish in 31.
The Spaniard tapped in at the par-five 12th and sank a 35-foot birdie at the 14th to climb to seven-under. Rahm then picked up another ball from 15 feet at the 17th and holing a six-footer to save par at the 18th to round it a flawless start.
Burns had set the early clubhouse target after shooting a bogey-free 64, with four birdies in a six-hole run starting at the second and four straight gains starting at the 11th putting him on top of the scoreboard.
Despite losing three strokes in the space of two holes on his back nine, Finau is in a group three shots behind the leader, with Dustin Johnson, Hideki Matsuyama, and Olympic gold medalist Xander Schauffele among the others tied for seventh.
Phil Mickelson, who started the week 70th in the FedExCup standings, started with a four-under 68, joining Bryson DeChambeau, Justin Thomas, and Paul Casey, while Jordan Spieth and Shane Lowry both shot 71s in the first round.
