Pittsburgh, PA (Sports Network) - Marlon Byrd went 3-for-4 and drove in two to help Carlos Silva stay undefeated, as the Chicago Cubs topped the Pittsburgh Pirates, 6-1, in a makeup game at PNC Park.
Silva (8-0) allowed one run on four hits and a walk in seven innings, and struck out five, in picking up the victory for a sixth consecutive start. He became the first Cubs starter to begin a season 8-0 since Ken Holtzman began 1967 with a 9-0 mark.
Ryan Theriot added two hits and scored four times for Chicago, which was making up the finale of a three-game series that was originally scheduled for June 2. Pittsburgh had won the first two games of the set.
Dana Eveland (0-1) allowed three runs in five innings to take the loss for the Pirates, who completed a homestand at 3-3 with the makeup.
