Patrick Dempsey coaches his sons' baseball teams

Patrick Dempsey has revealed his secret passion for coaching his sons' baseball teams.

The Grey's Anatomy star has a close relationship with his four-year-old twin boys Darby and Sullivan. He maintains their bond by teaching them the rules of the sport and how to bat like a pro.

He tells people magazine: "With the boys, we just finished T-ball season. My brother-in-law and I were coaching, and a lot of other fathers and mothers were involved.

"We watch all these young kids improve, learning how to have fun and be competitive about it."
