He's trying to show off. Even though he was safe, it's still a stupid play. He easily scores on a single.
He was trying to manufacture a run. He would have scored from 3rd on a sac fly or even a grounder to the right side.
would have walked home on the Guzman single.
no need to force the issue and go for third with a hot hitting Guzman and Zimmerman coming up.
stealing 2nd is plenty good enough.
