It wouldn’t be Father’s Day without a new dad gunning for a championship on the final day of the U.S. Open, would it?

Stepping into the Adorable Children of Famous Athletes void created when Riley Curry’s dad wrapped up the NBA championship is Tatum Gretzky Johnson, the son of Dustin Johnson. Little Tatum was born in January to Johnson and his fiancee, Paulina Gretzky and his actual appearances may be limited to his mother’s Instagram account, but he’ll be a constant presence on the course — his name is emblazoned on Johnson’s golf bag.

And if Johnson, who enters the final day in a four-way tie for the lead, wins? Well, we know this much: Tatum travels like a boss.

See you soon daddy!! ✈️⛳️ @djohnsonpga
