GOODYEAR, Ariz. -- The Reds claimed first baseman/outfielder Christian Walker off waivers from the Braves on Monday. To make room on the 40-man roster, reliever Jumbo Diaz was designated for assignment.
Walker was with Atlanta briefly after that club got him from Baltimore on Feb. 25, after he was designated for assignment. A right-handed hitter, Walker is a .148 hitter over 13 big league games with the Orioles in parts of the 2014-15 seasons.
