WASHINGTON (AP) -- Shortstop Julio Lugo has joined the St. Louis Cardinals and was available for Thursday's makeup game against the Washington Nationals.
Lugo was acquired Wednesday from the Boston Red Sox for outfielder Chris Duncan and a player to be named or cash. Lugo was hitting .284 with a home run and eight RBIs in 37 games with Boston, which designated him for assignment July 17.
To make room on the 25-man roster for Lugo, the Cardinals optioned right-hander P.J. Walters to Triple-A Memphis. Walters had a 9.58 ERA in eight appearances, including one start.
