AUSTIN - An amazing tee shot by Rory McIlroy led the world number three to join top-ranked defending champion Scottie Scheffler and second-ranked Jon Rahm in capturing clutch victories from Thursday's second group matches at the WGC Match Play Championship.
McIlroy made an epic drive with a stunning 375-yard blast at the 18th hole, landing the ball within four feet of the hole for a tap-in eagle that clinched a 2-up triumph over US 48th seed Denny McCarthy.
"It was good," McIlroy said. "I didn't think I could get it on the green."
Scheffler and McIlroy remained unbeaten while Rahm bounced back from an opening loss at Austin (Texas) Country Club, where 16 winners from four-man groups will advance to weekend knockout rounds.
Four-time major winner McIlroy, the 2015 Match Play champion from Northern Ireland, did not lead McCarthy until the par-5 16th hole, when McIlroy had a tap-in birdie and the American missed a seven-foot birdie putt to put McIlroy 1 up.
Then came McIlroy's clinching tee shot, which was airborne for 349 yards, nearly 70 yards longer than the average PGA Tour carry, before rolling up to the cup for a tap-in.
"I just played really well, played really solid," McIlroy said. "Didn't make a bogey and made some birdies when I needed to and thankfully was able to win."
Also in McIlroy's group, US 20th seed Keegan Bradley won his first WGC match in 11 years, ripping compatriot Scott Stallings 6&5.
McIlroy need only tie Bradley on Friday to advance.
Reigning Masters champion Scheffler, who won the Players Championship earlier this month, downed Swedish 38th seed Alex Noren 5&4 after only edging US 54th seed Davis Riley 1 up in a Wednesday opener.
"I just went out and played solid, no bogeys, and made some key putts," said Scheffler, who lost the first hole but won six, seven and the first four holes on the back nine with birdies.
"I just kind of kept the pressure on him and hit really good shots."
Rahm, a three-time PGA winner this year, bounced back from an opening loss to Rickie Fowler by beating US 39th seed Keith Mitchell 4&3.
The Spaniard made five birdies and a 14-foot eagle putt at the par-5 12th while never trailing to keep his title hopes alive.
"Not many mistakes tee to green," Rahm said. "Made a few birdie putts and got a comfortable lead."
Rahm needs a Friday victory over 2021 WGC Match Play champion Billy Horschel to have a chance to advance.
"Not many pairings are going to have more electricity on the course than me and Billy," Rahm said. "I'm going to have to get the win."
