The Washington Nationals made it official on Tuesday and acquired second baseman Alfonso Soriano from the Texas Rangers in exchange for outfielders Brad Wilkerson and Terrmel Sledge and minor league pitcher Armando Galarraga. The deal had been in the works since the winter meetings last week. Soriano is a four-time All-Star who has hit at least 28 home runs in each of the last four years. He was the only player to hit 30 homers and steal 30 bases in 2005. The 29-year-old finished last season with a .268 batting average -- his lowest since his first full year with the New York Yankees in 2001, but belted 36 homers with 43 doubles, 30 stolen bases and a career-high 104 runs batted in. "By acquiring Alfonso Soriano, we have added one of the game's dominant offensive players," said Nationals general manager Jim Bowden in a release. "We believe Alfonso's power from the right side and speed will take our lineup to new heights." Now, where will he play? The Nationals already have a three-time All-Star second baseman in Jose Vidro and Soriano has balked at the talk of him playing the outfield. In seven big league seasons with the Yankees and Rangers, Soriano -- dealt to Texas as part of the Alex Rodriguez trade before the 2004 season -- has 162 home runs, 465 runs batted in, 199 doubles, 169 stolen bases and a .280 batting average. Soriano became a regular for New York in 2001 and helped the Yankees to a pair of World Series appearances. He was the MVP of the 2004 All-Star Game. Wilkerson, meanwhile, had spent all five of his major league seasons with the Expos/Nationals franchise. He batted .248 with 11 homers and 57 RBI in 148 games last year and is a career .256 hitter. "We would like to thank Brad Wilkerson for his many contributions to our franchise and wish him all the best as his career moves forward," Bowden added. In two season with the Expos/Nationals, Sledge batted .267 in 153 games. He played in just 20 games last season after undergoing surgery to repair a torn right hamstring he suffered chasing down a ball in the outfield. Galarraga, a 23-year-old right-handed pitcher, spent time with Washington's Class-A and Double-A teams last season.
