Javier Vazquez has thrown the second most innings (2,320.1) and recorded the second most strikeouts (2,122) in all of baseball since the start of the 2000 season, but 2010 was the worst year of his career. His return engagement with the Yankees resulted in 157.1 innings of 5.32 ERA, 6.9 K/9, and 1.8 HR/9 ball, certainly not what they Yanks expected after trading three young players for him last winter.
After a performance like that, it stands to reason that Vazquez would have some trouble finding work for next season, but that hasn't stopped him from expressing interest in pitching for the Nationals according to MLB.com's Bill Ladson. The Nats are one team that we know is ready to spend on pitching, and Javy has long preferred the East Coast so he could be close to his family in Puerto Rico.
Vazquez obviously will not approach the $11.5MM he made each year from 2008-2010, and a multi-year deal is unlikely as well. A pitcher with his track record is a nice candidate for one-year, low base salary contract, and the Nats are in the perfect position to gamble on deals like that. It's worth noting that his fastball velocity dropped off considerably this season, so perhaps all those innings are finally catching up to him at age 34.
