The Red Sox have sent righthanded reliever Beau Vaughan to the Texas Rangers to complete an earlier trade for reliever Wes Littleton.
Vaughn, who will turn 28 in June, was 2-1 with a 2.12 ERA and 16 saves last season at Double A Portland. After a late-season promotion to Triple A Pawtucket, he went 1-1 with a 3.18 ERA. Overall, he struck out 69 in 58 innings.
Vaughn was selected by the Red Sox out of Arizona State in the third round of the 2003 draft — one round before they selected Jonathan Papelbon.
