CHICAGO (AP) – Zach Davies pitched into the sixth inning in his Chicago Cubs debut, leading his new team to a 4-3 victory over the short-handed Pittsburgh Pirates. Ian Happ homered and Kris Bryant reached three times as Chicago earned its second straight win after losing on opening day. Joc Pederson also drove in a run with a groundout. Davies, who was acquired in the December trade that sent Yu Darvish to San Diego, permitted two runs and four hits in 5 2/3 innings.
