Dustin Johnson's son takes it upon himself to steal Jordan Spieth's putter and attempt to putt himself. (0:15)

As world No. 1 Jordan Spieth warmed up for his third round on Saturday at the AT&T Pebble Beach Pro-Am, Dustin Johnson's 1-year-old son stole the show.

DJ's and Paulina Gretzky's son, Tatum, the grandchild of hockey legend Wayne Gretzky and Janet Gretzky, walked right up to Spieth and "borrowed" the two-time major winner's putter.

Spieth and Johnson were paired together for the first three rounds of the annual tournament that brings pro golfers and celebrities together. DJ played with his future father-in-law, "The Great One," while Spieth's partner was music star Jake Owen.

And yes, we believe Spieth retrieved his putter prior to starting his round.
