The unpredictable interaction between the rough and the clubface complicates precision in shots, especially on Oakmont's fast greens.

Players often face uncertainty regarding the position of the ball, the amount of grass behind it, and the direction of the grain, leading to frequent guesswork in their shot preparation.

The lack of control over how the ball reacts after hitting from the rough can lead to significant errors, compounding mistakes and resulting in high scores.

The ongoing US Open at Oakmont is showcasing the course as one of the toughest in golf, primarily due to its challenging rough.

The thick rough at Oakmont has not only snagged clubfaces but has also significantly impacted players' chances of advancing in the tournament.

As tournament play continues, effectively managing the rough will be vital for players aiming to excel at Oakmont.
