Mets/Cards - Spiezio Triple

[waltjp]

Does anyone have insight as to the controversy about Spiezio's triple in last night's Mets/Cards game? I saw the play but the sound was down so I didn't hear any speculation from the broadcasters (which was probably a good thing!).

If you didn't see the play, Spiezio hit a long drive to the wall in right field. Shawn Green reached over the wall and got a glove on the ball but didn't make the catch. The ball appeared to drop from his glove to the top of the fence and then onto the field.

LaRussa came out to discuss the play. The umpires huddled for a period of time and let the triple stand.
