Watch: FOX mixes up Brooks Koepka's current girlfriend with his ex

Moments after tapping in a par putt on the 18th hole at Erin Hills to win the U.S. Open, Brooks Koepka walked off the green and gave his girlfriend Jena Sims a kiss.

That's not an unusual occurrence at a golf event, but Sunday, FOX broadcaster Joe Buck identified Sims as Koepka's ex-girlfriend, professional soccer player Becky Edwards.

The error was corrected shortly thereafter, but not before Twitter had its fun.
