The Padres added a pair of veteran bats at Tuesday's trade deadline, acquiring third baseman Morgan Ensberg from the Astros. The Astros received a player to be named in exchange for Ensberg, who was designated for assignment Monday. Ensberg, 31, currently is mired in the worst offensive season of his career, batting .232 with eight home runs and 31 RBI in 85 games with the Astros.
