The PGA Tour got its first taste of the new rules over the last two week's in Hawaii, and now it's the European Tour's turn. The first Euro event of the year kicked off Wednesday and saw several pros navigating the rule changes. Some players had more trouble than others, like Henrik Stenson, who was caught on camera nearly messing up the new drop rule. During the first round of the Abu Dhabi HSBC Championship, Stenson ran into a situation that required a drop.

Stenson did just that, this time bending over to the correct height before letting his ball go. The European Tour tweeted a series of photos documenting the moment. https://twitter.com/EuropeanTour/status/1085495933842976768 Stenson isn't the only high-profile pro to run into trouble with the drop rule.
