WATCH: Jason Dufner has a hissy fit as he drops a shot during final round

No need for this carry-on.

One-time major winner, Jason Dufner, entered today's final round at the RBC Heritage at the Harbour Town Golf Links - South Carolina in pole position with a one-shot lead. As we found out earlier with Wicklow's Paul Dunne, entering the final day as tournament leader can bring a lot of pressure. Dufner, who won the US PGA in 2013, is looking for his first Tour victory since January 2016 where he won at the CareerBuilder challenge at PGA West. After nine holes, Dufner is currently one shot off the pace after shooting three bogeys on the front nine. His second bogey of the day, which occurred on the fifth hole, seemed to get the best of the Cleveland native. He's clearly pissed off for bogeying another hole but his reaction to this isn't exactly something we see too much in golf. https://twitter.com/LooseImpediment/status/853686989102751744 After he secures the bogey, Dufner drops the putter on the green and walks off in a huff - leaving his caddy with the job of picking up after him. Not exactly admirable behaviour. Safe to say this didn't go unnoticed and there wasn't much support for the 40-year-old. https://twitter.com/BovDaz/status/853700170340544513 https://twitter.com/TristanORourke/status/853699749752561665 https://twitter.com/ecosse1967/status/853699138642481159 https://twitter.com/JimMcLaggan/status/853698242919452673 https://twitter.com/OwenLong33/status/853698182974492673 https://twitter.com/moops20point5/status/853694398080724994 https://twitter.com/lindsaypinckney/status/853694032936976384 https://twitter.com/CoachesHotSeat/status/853692459393712128 At the time of writing, Dufner is tied for second through 10. One shot behind leader Ollie Schniederjans.
