Sergio Garcia's inaccurate tee shot on the third hole at the Bridgestone Invitational knocked the diamond out of a woman's ring. Call it a diamond in the rou—never mind, everyone made that joke already.
Garcia gave the woman an autographed ball and asked for contact information to deal with replacing or fixing the ring before he kept playing. Fortunately, another person found the diamond in the grass. A happy ending!
