Red Sox trade Lugo to Cards for Duncan

The Red Sox have made their second move of the day.

Boston has agreed to send shortstop Julio Lugo to the Cardinals for outfielder Chris Duncan, a major-league source has confirmed.

The trade was reported earlier Wednesday by other media outlets, including the Boston Herald.

The move comes hours after an earlier trade sent two Red Sox prospects to the Pirates for first baseman Adam LaRoche.

Lugo was designated for assignment last week and the Red Sox had until Monday to trade or release him. He is hitting .284 in 37 games this season.

“We’re optimistic that he will respond positively to a fresh start here in St. Louis,” Cardinals general manager John Mozeliak said.

Lugo, who signed a $36 million, four-year free-agent deal before the 2007 season, was designated for assignment Friday and is owed about $13 million through next season.

General manager Theo Epstein has called Lugo’s contract “a mistake” and “a lesson learned.”

Duncan is hitting .227 with five home runs in 87 games this season. He was optioned to Triple-A Memphis earlier Wednesday. St. Louis recalled infielder Brian Barden to take his roster spot.

The Herald reported Duncan will report to the Red Sox’s Triple-A affiliate in Pawtucket.
