Ahh... baseball season has started. Every weekend until May is booked. Devin is an Oriole, which is awesome because orange is his favorite color. So far he's established himself as the outfield dancer. (I think this video had a big impression.) My favorite is the dance that I call "The Butter Churner" (it's exactly what you're picturing), followed closely by "Slow Motion Running".
Even though he's not the most serious player, he sure looks professional, which is completely adorable.
