Jon Rahm endured an interesting day at the PGA Championship on Friday - and by interesting, it was certainly memorable, even if it was for the wrong reasons.The Spaniard began the second round with an erratic, wayward drive that hit an onlooking spectator, forcing the fan to leave the course with medics due to precaution.The fan was given a piece of memorabilia from Rahm, however, to make up for the wayward shot, but he may not have been best pleased having to evacuate the course to be checked up.That shot would set the tone for the rest of his day at the Bellerive course in Missouri.Having played his effort at the par-5 eighth (his 17th), he was left in the rough and in search for his ball.Sometimes, a player often needs a marker to lay down to display where exactly his ball is in order to play his forthcoming shot.However, Rahm did not get this opportunity to lay down a marker, and accidentally stepped on his ball, unintentionally touching it with the top of his foot.The 23-year-old consulted a course official following on from the accidental incident that he found himself in - and though he was honest enough to own up to his mistake, Rahm was hit with a one-shot penalty for his troubles.Unsurprisingly, this seemingly harsh decision didn't go down well with golf fans on Twitter, and the reacted in their thousands.

You can watch the full incident in the video below, and you can even hear what is being said, and you have to feel sorry for Rahm.

In his exchange with the course officials, Rahm seemed confused with the issue that had been presented, however, he bounced back.

Rahm later finished the round on -3 under heading into the third round of the Championship, and he currently finds himself five shots off the lead, tied in eighth position at the current state of proccedings.
