The Red Sox are among the teams interested in acquiring Tampa Bay Devil Rays infielder Ty Wigginton, according to a major league source, though a source familiar with the Sox said a trade was not close as of yesterday afternoon. Wigginton, a righthanded batter, is hitting .274 with 15 home runs, 48 RBIs, and a .326 on-base percentage this season. Wigginton is 29 years old and has played 36 games at second base this season, 32 at third, 17 at first, and 15 as the designated hitter. Major league sources also have confirmed the Sox have interest in Texas first baseman Mark Teixeira; White Sox right fielder Jermaine Dye; Oakland outfielder Bobby Kielty, who was recently designated for assignment; and Dodgers third base prospect Andy LaRoche, who has been hot in Triple A Las Vegas, a team the Red Sox' Allard Baird has been scouting.
