The Pirates acquired first baseman Chris McGuiness from the Texas Rangers organization Monday in exchange for right-hander Miles Mikolas.
McGuiness, 25, made his major league debut in 2013. He spent most of the season with Class AAA Round Rock, where he hit .246 with a .369 on-base percentage and 11 home runs in 436 plate appearances. He hit 23 home runs while with Class AA Frisco in 2012.
The Rangers designated the left-handed McGuiness for assignment last week to make room for Shin-Soo Choo on the 40-man roster. The Pirates added McGuiness to their 40-man, according to their official Web site Monday. He still has minor league options remaining and could begin the season at Class AAA Indianapolis.
The Boston Red Sox originally drafted McGuiness in the 13th round out of the Citadel in 2009. He went to Texas in the deal that sent Jarrod Saltalamacchia to Boston. The Cleveland Indians selected him in the 2012 Rule 5 draft, but returned him to Texas.
The Pirates traded for Mikolas, 25, in late November, receiving him and outfielder Jaff Decker from the San Diego Padres in exchange for Alex Dickerson.
Mikolas pitched in two games for the Padres in 2013, but had a 3.62 ERA in 25 relief appearances in 2012.
