The Nationals will place catcher Carlos Maldonado on the disabled list with a back injury before Thursday's game and recalled first baseman/outfielder Tyler Moore from Class AAA Syracuse, manager Davey Johnson said following tonight's 5-3 win over the Mets.
Maldonado hasn't appeared in a game since May 29 in Miami and has been experiencing what he referred to as back spasms ever since. The 33-year-old is 0-for-9 with an RBI in four total games since joining the Nationals' roster three weeks ago after injuries knocked out both Wilson Ramos and Sandy Leon.
Moore returns only one week after he was optioned to Syracuse. The slugger had only three hits in 17 big-league at-bats but picked up right where he left off when he returned to Class AAA, going 9-for-21 with two homers in his first five games back in the minors.
In other injury news, veteran utilityman Mark DeRosa will begin a rehab assignment for Class A Potomac either Thursday or Friday, Johnson said. DeRosa has been out since late April with an oblique strain.
