Question: why are the players in the ryder cup wearing yellow ribbons?
Answer: Ryder Cup players will wear yellow ribbons during the 2018 Ryder Cup to honor Spain's Celia Barquin Arozamena, the former Iowa State champion golfer who was killed on a golf course last week. "The golfing family extends way beyond what we are trying to do this week," European captain Thomas Bjorn said.
