Former world No. 1 Jon Rahm said on Wednesday he had not done himself "any favours" in his winless start to the season ahead of LIV Golf's South Korea debut.
The Spaniard has endured an indifferent 2025 by his own lofty standards, admitting "small mistakes" had cost him.
He failed to mount a serious challenge at last month's Masters and he vowed to clean up his game in South Korea with the second major of the year, the US PGA Championship, only two weeks away.
"I'm just not doing everything I need to do right," Rahm said ahead of LIV Golf Korea, which will also feature US Open champion Bryson DeChambeau, who played alongside eventual winner Rory McIlroy in the final group at Augusta.
"Sometimes you also need a little bit of luck in your favour, not that I haven't been lucky.
"I just haven't done myself any favours on the golf course, I would say it like that," added Rahm.
The two-time major winner will tee off in Friday's first round at the Jack Nicklaus Golf Club in Incheon alongside the in-form Joaquin Niemann of Chile, who won his third LIV tournament of the season in Mexico last weekend.
The 2023 Augusta champion had a frustrating time at this year's Masters, starting poorly with a three-over 75 and leaving himself with too much to do heading into the weekend.
He picked up his game but the damage had been done as he finished eight shots behind McIlroy for a share of 14th place.
'WINNING IS WHAT MATTERS'
Rahm was second in the Saudi-backed breakaway circuit's season-opening event in Riyadh and has finished in the top 10 in all six tournaments, which have a field of 54 players.
"While I like having top 10s and I like being a good player week-in and week-out, winning obviously is what matters more," he said.
"I would gladly give up some of those top 10s for more wins.
"I keep playing well, I keep putting myself close enough, just every once in a while there've been enough mistakes where I'm just not quite close enough going into the back nine on Sunday."
Niemann's victory in Mexico secured his berth at the US Open at Oakmont in June.
The Chilean added to the titles he won in Singapore and Adelaide this season.
"It's been an exciting last six events here at LIV, the way I've been playing, the way I've been feeling on the course," said the 26-year-old.
"I felt like there's been a lot of trust and a lot of faith in the work that I've been putting in."
