He's on the chick show Grey's Anatomy these days. You guys may know him better as the guy who does the voiceover for all the recent Mazda commercials, including the new 3 ones. That's why he's wearing the cap.
I'm ashamed to say I know him because of the soap that my gf makes me watch with her, but then I found out he loves Mazda and races cars, so he gets a pass for being in girly shows.
