After all the hype the Red Sox received during the offseason, I can't rank this anywhere else but No. 1. The Red Sox made two really big moves in the offseason, acquiring Adrian Gonzalez from the Padres and signing Carl Crawford to a mammoth deal.
The Red Sox were the easy favorites to win the AL East and even the World Series. People said they had the best lineup in baseball and a historic pitching rotation. Add in a dynamic bullpen, and you have a team that could potentially unseat the 1927 Yankees as the best team of all time.
The Red Sox started the season 0-6, but after that, they cruised for most of the year. The Red Sox entered September leading the Yankees in the AL East. They also maintained a nine-game lead over the Rays, who were trailing the Yankees in the wild-card race. The Red Sox collapsed, winning just seven games in September. They completed the biggest collapse of all time, forcing everything to come down to the last game of the season.
The Red Sox played the Orioles, while the Yankees played the Rays. During the middle of both games, it looked like Boston would be getting to the postseason. While the Red Sox led by one, the Rays trailed by seven to the Yankees.
The Rays scored six times in the bottom of the eighth to make it a one-run game. They were down to their last strike when Dan Johnson crushed a home run to send the game to extras.
While the Rays game continued, the Red Sox got the Baltimore Orioles down to their final strike with Papelbon cruising through, striking out the first two batters with ease. Then Nolan Reimold drove in a run to tie the game. A few pitches later, the Red Sox lost on an RBI single from Robert Andino.
Just minutes after the Red Sox lost, Evan Longoria launched his second homer of the game, a walk-off home run to propel the Rays to the playoffs.
