Brooks Koepka said it will take a while to get over missing out on winning the Masters after seeing Jon Rahm take the green jacket after Sunday's final round.
Koepka had led for the first three rounds at Augusta, only to finish tied for second with Phil Mickelson, four shots behind eventual winner Rahm.
Speaking after his final three-over round of 75, the 32-year-old did not believe he played well enough, but also failed to get "good breaks".
"Obviously it's super disappointing," he said. "I didn't play good enough to win. Hit some shots where I also feel like I didn't get some good breaks, the ball on nine; on four and six, I hit some good shots and just ended up in some terrible spots where it was quite difficult.
"Then 12, it was just kind of interesting, Jon hit nine and I hit a wedge over the green. Then 14, I felt like I just had to make a run for it. Didn't feel like I did too much wrong, but that's how golf goes sometimes."
Koepka also claimed that the pair in front of him and Rahm – Patrick Cantlay and Viktor Hovland – were slowing them down, saying: "Yeah, the group in front of us was brutally slow. Jon went to the bathroom like seven times during the round, and we were still waiting."
With two LIV Golf players in Koepka and Mickelson in the top three, the former said it proved they can compete just as well as their PGA Tour counterparts.
"I mean, we're still the same people," he said. "I know if I'm healthy, I know I can compete. I don't think any of the guys that played this event thought otherwise, either. When Phil plays good, we know he's going to compete. [Patrick] Reed, the same thing.
"I think that's just manufactured by the media that we can't compete anymore; that we are washed up."
He added: "The way Jon played today was pretty impressive. I don't know, the game, it's so good right now, everybody, it's amazing to see all these guys compete. When they are at their best, they are all tough to beat."
Having also finished tied for second at the 2019 Masters, Koepka said he will not initially see the positives in such a high finish at a major, but will eventually do so.
"Probably not. Not today. Probably not for the next few days. But eventually it will be a positive," he said. "I'd say probably give it a week, and I'll start to see some positives out of it and carry this over to the PGA, the US Open and The Open.
"But right now, it's kind of tough to see, if I'm honest, probably for the next few hours and the next few days."
