Arnold Palmer honored at the US Open on 18th flag at Erin Hills

The 18th hole has been a memorable one this weekend from Erin Hills at the U.S. Open.

The hole, which is well over 600 yards, reaches 675 yards when played at its maximum length. Jordan Speith made the hole famous in the 2011 U.S. Amateur Open when he went "bunker to bunker to bunker," for a bogey in his quarterfinal loss. Justin Thomas made the hole part of history on Saturday, eagling the 18th en route to a 63, and a 9-under to break Johnny Miller's single-round record.

On Sunday, the flag at the tricky 18th is decorated with an image of Arnold Palmer.

Today, the 18th, whether it be watching a birdie, bogey or more history being made, will serve as a tribute. The King's silhouette adorns the red flag, signalling to Arnie's Amry everywhere. Palmer won the 60th U.S. Open at Cherry Hills Country Club in Englewood, Coloradoback in 1960. The beloved golf folk hero passed away on September 25, 2016.
