If I were making this cake, I would do the ball in the ball pan from Wilton (I'm sure it has a clever name, but I don't know it), and I'd make the other cake and get it all iced (except the green on top. I'd ice the ball (on it's own board) and get it all smooth like normal. Then I'd take the opposite end of a large artist's paintbrush, or anything you might have with an end like that and press it in the ball, all over. Then I'd put the ball on the other cake and finish it up.
Someone had used the end of a candy thermometer to make the dimples on the ball. (I'd been looking how to do this because I want to make one for my dad for his birthday.) I think you need something thicker like that for the indents to match the scale of the sports ball pan size.
