If you haven't guessed it already, Javier Vazquez is undoubtedly the most disappointing pitcher in the past 10 years of New York Yankees baseball.
And why is he here? Because he was so not nice, that he did it twice.
Unlike the rest of his worthy opponents on this list, Vazquez tanked in two separate stints with the team.
On December 16, 2003, Vazquez was acquired by the Yankees in a trade with the Expos that sent Nick Johnson, Juan Rivera and Randy Choate to Montreal. After being picked up by the Yanks, Vazquez was an extremely popular American League Cy Young pick amongst many experts at the time.
And to Vazquez's credit, the start of his 2004 campaign was nothing short of impressive. He went 10-5 with a 3.56 ERA in his first 18 starts, earning him an All-Star nod.
But the second half of the year was just about the opposite for Vazquez.
He finished the season with a 4-5 record and had a terrible 6.92 ERA. That very same season, Vazquez would be inserted into the infamous 2004 ALCS Game 7 as a source of relief.
The only relief he gave was to Red Sox fans after allowing perhaps the most devastating home run ever given up by a New York Yankee. It would be one that would rival that of Bill Mazeroski's walk-off, World Series-winning homer in 1960.
The knockout grand slam by Red Sox center fielder Johnny Damon capped off a 4-3 series victory for Boston in the championship series and propelled them to their first World Series title in 86 years.
Vazquez would later reveal that he suffered from a nagging elbow injury throughout the second half of that season, something he failed to tell team officials during the year.
But in 2010, the Yankees needed some starting pitching and the history of Javy seemed to be in the past.
On December 22, 2009, the World Series champs shipped Melky Cabrera, Mike Dunn and Arodys Vizcaino to the Atlanta Braves for Vazquez and Boone Logan.
Well, at least the Yankees received Logan in that deal.
In his second go-round with the Yanks, Vazquez went 10-10 with a 5.32 ERA in 26 starts. He would later be moved to the bullpen in an attempt to salvage any part of his ability.
After failing to live up to the bill as one of the game's best pitchers at the time, Vazquez was left off the postseason roster by manager Joe Girardi in 2010. It was an appropriate testament to Javy's performance that he couldn't even find a spot in a rather thin bullpen.
His playoff exclusion was just the icing on top of one of the most failed New York Yankee careers of all time.
