Nationals outfielder Alfonso Soriano and right-hander Tony Armas Jr. were two of 24 Major Leaguers who filed for free agency on Sunday. The Nationals' other three free agents -- catcher/first baseman Robert Fick, outfielder Jose Guillen and right-hander Ramon Ortiz -- have yet to file. The Nationals have made it clear that they want Soriano back as their left fielder, but they are willing to take two draft picks -- a first rounder and sandwich pick in 2007 -- if Soriano decides to sign with another team. "We love Alfonso, and we are certainly going to continue to explore having him back, but we have always known that if we didn't have him back, we would have two very, very important picks," team president Stan Kasten said early this week. "We need to build up our [farm] system. Either way, we feel very comfortable."
