You have a legit gripe. I was watching the game because the under 8.5 was my best bet and I was flipping out also when Bucknor almost single-handedly cost it in the fifth.
One, the official Major League Baseball rules do not allow an umpire to grant a timeout to a batter when the pitcher has already begun his motion. In the case of Bourn, he simply put his hand up and backed away WHILE SANTANA BEGAN HIS WIND UP, and Bucknor granted him the timeout for some reason, as Santana was making his pitch, and the pitch actually ended up in the strike zone, which SHOULD have been called strike three by Bucknor. So, instead of the run-scoring double that Bourn produced in that at-bat, he would have been out, which would have been the second out in the inning, with still no runs on the board.
Two, I also noticed that his strike zone became inconsistent at that point. He was literally calling pitchers in the same exact spot on the outside black that were strikes for Sheets and balls for Santana. I believe that was a clear observation that not only you and I made, but also Terry Collins and his staff (Which is why they came out of the dugout and were flipping out) and the Mets' mostly unbiased announcers. Without question, that is what led to the floodgates being open in the inning, and without that obvious frustration from bad calls that completely threw Santana off his game, this would have been a different ballgame with a potentially different outcome.
Sorry about your loss but at least my under held on
I'm only an over/unders guy but in my opinion, it might be a decent idea to fade the Mets from here on out, at least in the near-future (Such as their series coming up against the Nationals). Coming off a sweep in Atlanta, they look their wheels are coming off a bit, and with no real veterans that have steered winning clubhouses in this situation before, it's probably more likely that will happen.
