White Sox acquire left-handed prospect from Rays

DETROIT -- The White Sox acquired left-handed reliever Frank De Los Santos through a trade with the Rays on Saturday for a player to be named or cash.

De Los Santos will be a part of Chicago's 40-man roster, but he will not be added to the active Major League roster for the final week of the season. This move was unrelated to the trade that sent Jesse Crain to Tampa Bay in July.

The 25-year-old Dominican went 1-2 with a 5.34 ERA over 26 appearances this season with Triple-A Durham, striking out 21 in 32 innings. He dominated left-handed hitters, holding them to a .167 batting average in 41 at-bats.

De Los Santos, 6-foot and 165 pounds, didn't start playing baseball until he was 16 years old and was signed by the Rays as a free agent in 2007.
