It's been a good week for Dustin Johnson. He became the new No. 1 ranked player in the world last Sunday with a dominant win at the Genesis Open, and this weekend he found out that a second son is on the way.

Dustin Johnson and Paulina Gretzky are expecting their second child, and the couple found out the gender of the baby by having Johnson crush an exploding golf ball.
