Nationals Scouting Javier Vazquez

The Nationals are scouting Javier Vazquez as GM Mike Rizzo traveled to Puerto Rico this evening to watch the veteran right-hander pitch, reports Ken Rosenthal of FOXSports.com (on Twitter). While Washington already has one of the strongest rotations in all of baseball, adding an insurance arm may make sense given Dan Haren's health issues last season.

Vazquez has been contacted by 15 teams about his services, but does not plan to sign with a club until after the World Baseball Classic in March and will only consider pitching for a contender, writes Jim Bowden of ESPN.com (via Twitter). The former All-Star last pitched for the Marlins in 2011 where he posted a 3.69 ERA with 7.6 K/9 and 2.3 BB/9 in 192.2 innings.
