Michigan head coach Jim Harbaugh was a guest of the Oakland Athletics in Arizona on Saturday.

Harbaugh, who was dressed in the full uniform, told reporters before the game he may coach first base for the A's spring training game.

Harbaugh was put in the game, and it looks like he took his job very seriously.

Harbaugh also tweeted congratulations to Big Sean on his first No. 1 Album, Dark Sky Paradise, so it looks like the coach has had a busy morning.
