According to Bill Ladson of MLB.com, the Washington Nationals are seeking outfield help and are interested in trading for Diamondbacks outfielder Gerardo Parra. Ladson says with the surplus of pitching, the club can move John Lannan who is "almost a certainty that he (John Lannan) will be dealt before the start of the season."

It's not known whom the Nationals would trade for Parra. Left-hander John Lannan is on the trade block, and it's almost a certainty that he will be dealt before the start of the season. The Nationals currently have a surplus of starting pitching.

Meanwhile the D'Backs signed outfielder Jason Kubel to play left, pushing Parra into the backup outfielder role for all three outfield positions for Arizona. While Parra is a really good defender and enjoyed a breakout season last year, it would make sense for the club to move him if he isn't playing everyday. However, like the Nationals, they don't necessarily need more pitching either

The 24-year-old Parra hit .292/.357/.427 in 493 plate appearances last season. According to UZR (ultimate zone rating), Parra saved over 23 runs in the outfield these past two seasons.
