Clayton Kershaw and Kenley Jansen have two of the more unique windups in baseball, which makes them ripe for imitation. This fact is not lost on Kershaw and Jansen themselves, and so they spent some time before a recent game working to perfect their imitations of each other.

Both guys do a good job here, but I think Jansen's portrayal was the most accurate. He's got the stretch and weird wrist-bend down pat.
