MLB.com's T.R. Sullivan writes that the Rangers have claimed first baseman Joe Koshansky off waivers from the Rockies.
Koshansky, 26, led the minor leagues with 121 RBI last year. He also swatted 31 home runs while hitting .300. He's been added to the Rangers' 40-man roster and is expected to begin the season at Triple-A Oklahoma as the starting first baseman.
