CHICAGO -- Ryan Dempster has been so good of late he did something Friday afternoon that was unseen around these parts in nearly five decades.

Dempster delivered seven shutout innings and the Cubs finished off a 3-0 victory over the Boston Red Sox despite three errors from its defense.

According to Elias, it’s the first time the Cubs have shut out an opponent at Wrigley Field with at least three errors in nearly 47 years. On July 11, 1965, the Cubs took down the St. Louis Cardinals 6-0 despite making three errors in the first game of a doubleheader.

Everybody on the Cubs’ infield seemed to get error fever Friday. Second baseman Darwin Barney, shortstop Starlin Castro and third baseman Luis Valbuena all made miscues on ground balls, although Castro’s came when he was playing in shallow right-center field on the defensive shift against the Red Sox’s David Ortiz.

Through it all, Dempster managed to extend his personal scoreless streak to 22 innings.
