2013 Red Sox -- Joel Hanrahan (RHP)
Back in 2013, this Red Sox team was un.stop.able. They never lost more than two games in a row, they were spirited, and had the ENTIRE city, not to mention the entire STATE behind them - especially after the events on April 15, 2013.
There were memorable characters in Mike Napoli, Jonny Gomes, Shane Victorino. Xander Bogaerts was a mere rookie, and Will Middlebrooks was getting more playing time by the day. Yes, there were unique endings to games 3 and 4 in St. Louis, as game 3 ended on an obstruction call and game 4 on a pickoff by Koji Uehara (both World Series firsts), but one person you almost never hear anyone bringing up from 2013 is Joel Hanrahan.
Going into the season, he was supposed to be their closer, but that plan was quickly squashed when Hanrahan had to undergo forearm surgery - ending his season, and his career as Hanrahan would never pitch again at the big league-level.
In 2013, he made just nine appearances collecting an 0-1 record, a 9.82 ERA, and five to four strikeout-to-walk ratio. He also had four saves before his career-ending injury.
