In the fall, Zach was cheered on by his two favorite people -- his wife and son Madden.

A video shared by the team on Instagram showed Julie holding Madden up against a railing as Zach came over. The proud mom passed the baby down to him while Dad snuck in a quick kiss and a photo as he warmed up for the game.

As he passed Madden back, Zach shared a kiss with Julie, in a sweet moment she shared on her Instagram, simply captioning the shot, "Family ❤️."
