Jon Rahm is a passionate, Spanish player who has emerged as arguably Europe's best golfer and most consistent performer on the PGA Tour.
It is fair to say that the World No. 3's temper has boiled over on previous occasions, but I'm sure we can all sympathise with Rahm as golf can be an agitating and infuriating sport.
A major championship victory is surely just around the corner for the 26-year-old and heading into the weekend, he is only two shots behind surprise leaders Richard Bland and Russell Henley. Despite his solid round of 1-under-par on Friday, he was asked about keeping his cool in San Diego.
"Am I ever going to escape that question? Like I never lost it. I got a little frustrated on a couple of holes," said Rahm.
"Just because, like I said, I felt like I was making decent swings but just not getting the results sometimes that you'd expect with certain swings. They weren't that bad. I just kept going off the fairway and off the fairway and off the fairway.
"I was a bit more vocal on 14 after the second shot because I felt that was a good swing and I felt like it just got gusted. But, hey, I made the next shot, so I can't really say much. I never really lost it."
You could argue that Rahm's passion and aggression is one of his qualities and if so, it has certainly worked up until now. The man from Barrika, Spain has won five times on the PGA Tour, most recently at the BMW Championship in 2020.
Rahm is currently tied fifth at the US Open and is set to tee it up with two-time Masters champion Bubba Watson later today in the third round.
