You may have noticed something on Lydia Ko's right arm during her victory walk up the 18th hole at Royal Melbourne as she was capping off a win at the ISPS Handa Women's Australian Open.
No, it wasn't Sharpie. The 17-year-old world No. 1 has a tattoo on her right wrist.
The ink is of the date she won her first tournament as a pro: April 27, 2014 when she took the Swinging Skirts LPGA Classic. It's in Roman numerals, however, so it looks like this: IV XXVII XIV
Of the occasion, Ko said, "My parents were there and I felt like it was a very memorable win so I got that tatted up."
Ko joins Bubba Watson as the only pros with visible tattoos. Watson has the name of his wife, Angie, tattooed on his wedding ring finger.
