We were wondering what that was about! We were way high up, and when Lo Duca was injured just about the whole stadium started booing. We got up and looked, and the Astros catcher was pointing directly back behind the plate into the stands - the umps came over - but we couldn't see what was going on. Thanks for posting this, very interesting. It was a really odd incident.
Sucks for Nieves - who was charged with the K after one swing...
