Tour pro addresses Jon Rahm's struggles after disastrous display

English professional golfer Eddie Pepperell believes Jon Rahm's disastrous display at Wentworth was simply an anomaly.

Rahm was the highest-profile player to miss the cut last week at the BMW PGA Championship.

The Spanish two-time major champion carded rounds of 78-77 on the West Course to miss the cut by 10 strokes and finished last among the players who completed 36 holes at the DP World Tour's flagship event.

Questions were raised as to whether Rahm was affected by the fact his future with LIV Golf is yet to be resolved, but Pepperell believes we shouldn't read too much into it.

"I don't think there's much to touch on there, apart from the fact I would put that down as just an anomalous performance," Pepperell told the latest edition of The Chipping Forecast.

"There's clearly stuff going on in his head. I think that has to be, I think it has to be the case.

"There's stuff going on behind the scenes that is perking him and making him, rendering him unable to play his top level at the moment.

"That being said, I wouldn't read too much into one week and [that's] coming from me talking about a LIV player.

"I would be more than ready to usually jump on the bandwagon there.

"I think Jon is such a unique talent and a generational talent.

"But I mean, it is odd to see him finish last of players that finished. I mean, that does suggest something's off."

Pepperell explained he knew Rahm was struggling as he watched the coverage from the first round of action when the former Masters champion made a bogey from nowhere at the 11th.

"I think it was his third hole, because from memory he started in the morning on hole nine," he said.

"He hit a great tee shot up the 11th. He had 95 yards and he careered it long and right.

"And I think he ended up making a bogey, I think he made a double bogey from 95 yards.

"And I thought to myself watching it, anybody can do that. But the best players hardly ever do that.

"And when you're seeing a player struggling, that's the kind of s--- that you do when you're struggling.

"You make terrible bogeys from 100 yards. And so it was that when he did that, I thought, my God, he really is off with his game.

"Because you just do not see that very often at all from the very top players."

Rahm's next appearance is likely to come at the Open de España in Madrid from October 8-11. 

He had previously said he was planning to play the event, although his participation was dependent on the arrival of his fourth child. 

He is also scheduled to play the Abu Dhabi Championship and the season-ending DP World Tour Championship in November.

Rahm's future with LIV has also become increasingly complicated. 

Earlier this month that he was "more than willing" to fulfil his existing LIV 1.0 contract, but LIV Golf has since filed for Chapter 11 bankruptcy protection and is seeking permission to reject a number of player contracts, including Rahm's.
