So far in the young 2006 season, Alfonso Soriano has given the Washington Nationals a legitimite power threat in the middle of the line-up even playing in the spacious RFK stadium.  Soriano has played decently in LF, so far he hasn’t been a liability and with time he should be pretty decent in the outfield.  He’s already a better fielder than Manny Ramirez, so as long as Soriano hits, the defense should suffice.  The player they traded to acquire Soriano, Texas Rangers LF Brad Wilkerson has struggled striking out an American League-leading 23 times.  The trade though did leave a void in the lead-off spot for the Nationals.  Rookie Brandon Watson has already been demoted back to the minors, and the team has recalled Ryan Church to replace him.
