The Rangers acquired right-hander Tim Wood from Pittsburgh on Thursday in a trade-waiver claim.
The 28-year-old Wood was assigned to Triple-A Round Rock. The Rangers sent $25,000 to Pittsburgh to complete the transaction.
Wood made 13 appearances for Pittsburgh this season, going 0-3 with a 5.63 ERA before being designated for assignment on Friday. Pittsburgh signed Wood to a minor league contract March 31 after he was released by Washington.
His only stint in the big leagues this year was from June 10-July 1. He spent the rest of the season with Triple-A Indianapolis, going 2-0 with league-leading 23 saves and a 2.84 ERA in 40 relief appearances.
With the move, the Rangers have a full 40-man roster.
