D-backs pluck Rodriguez from Sox

CHICAGO -- The Arizona Diamondbacks, obviously well informed of the Chicago White Sox's player-personnel this winter, moved Friday to claim left-hander Santos Rodriguez off waivers.

Maybe that's one of the downfalls of making two deals with a team over a matter of days: a club can get to know a lot about your assets.

The White Sox first acquired center fielder Adam Eaton from the Diamondbacks in early December and then acquired third baseman Matt Davidson from Arizona a week later.

Rodriguez was designated for assignment last week when the White Sox made the signing of left-handed reliever Scott Downs official. To keep Rodriguez the White Sox first had to slip him through waivers, but were unsuccessful.

Rodriguez pitched as high as Triple-A Charlotte in each of the past two seasons. He made 18 relief appearances with the Knights last season, posting a 7.30 ERA after posting a 2.35 mark in 15 appearances at Double-A Birmingham.

The 26-year-old Santos was signed as a free agent out of the Dominican Republic by the Atlanta Braves in 2006 and was acquired by the White Sox in 2008, arriving with Tyler Flowers and Brent Lillibridge. The trade cost the White Sox both Javier Vazquez and Boone Logan.
