Rory McIlroy and Bryson DeChambeau stayed alive at the WGC-Dell Technologies Match Play, where world number one Dustin Johnson showed why he is golf's top-ranked player.
McIlroy extended his campaign at the Austin Country Club with a confidence-boosting 4 and 3 win over Lanto Griffin on Thursday.
Four-time major champion McIlroy endured a forgettable opening day in Austin on Wednesday, playing a tee shot into a swimming pool during a shocking 6 and 5 humbling at the hands of Ian Poulter.
But McIlroy – who missed the cut at The Players Championship – bounced back on day two, though the Northern Irishman still has his work cut out in the round-robin group phase after Poulter defeated Cameron Smith.
In order for McIlroy to advance from Group 11, the former world number one must beat Smith in the final match while also requiring leader Poulter to lose to Griffin.
"That was big," said McIlroy. "Obviously winning the match today keeps me in the tournament and gives me hope for tomorrow. It looks like Lanto is going to have to do me a favour and beat Poults.
"I hit a couple of destructive shots yesterday, but overall both of us played well, and I didn't feel the scoreline matched up with how I felt like I played. And then the same thing today. I played solid. Lanto didn't have his best stuff, but I played solid and kept it in play and holed some good putts when it mattered."
U.S. Open champion DeChambeau also breathed life into his campaign as the American star narrowly avoided elimination.
After suffering an upset at the hands of unheralded Frenchman Antoine Rozner on day one, DeChambeau was forced to dig deep against Kim Si-woo.
Down one, fifth seed and Arnold Palmer Invitational winner DeChambeau prevailed 2 and 1 after Kim's tee shot on 17 found the penalty area.
DeChambeau needs to beat Group 5 leader Tommy Fleetwood to have a chance to qualify for the weekend.
Top seed Johnson flexed his muscles as he came from behind to deny rising star Robert MacIntyre.
MacIntyre was on the verge of a prized scalp before Johnson rallied to tie the Group 1 showdown, having been two down with two to play.
The pair have one and a half points from two matches heading into their final matches.
World number two and Players Championship winner Justin Thomas, meanwhile, crashed out following a 2 and 1 defeat to defending champion Kevin Kisner.
