Jake Arrieta threw seven shutout innings and Nate Schierholtz drove in three runs to lead the Chicago Cubs to a 7-0 win over the Cardinals on Friday afternoon at Wrigley Field.

Arrieta (1-0) allowed two hits and struck out seven for his first win with the Cubs in is second start since coming over in a trade from Baltimore.

Cardinals starter Jake Westbrook walked the first three batters he faced in the bottom of the first inning and three scored on a two run single from Schierholtz, and a single by Donnie Murphy.

The Cubs added a run in the fifth on Schierholtz’s sac fly and then scored two more in the sixth on a run-scoring double by Darwin Barney and a safety squeeze bunt by Arrieta. The final run in the seventh scored on a wild pitch.
