Walks, errors help Cubs beat Pirates in 12 innings

PITTSBURGH — Aramis Ramirez’s sacrifice fly scored the go-ahead run during a two-run 12th inning in which the Cubs didn’t have a hit off rookie Evan Meek, and Chicago rallied after squandering a seven-run lead to win the Pittsburgh Pirates’ home opener 10-8 Monday. Former starter Jon Lieber (1-1) gave a depleted bullpen a big lift with three scoreless innings before Carlos Marmol finished up in the 12th for his first save since June 27, helping the Cubs win their third in the row.
