CHICAGO (AP) - Jake Arrieta threw seven shutout innings and Nate Schierholtz drove in three runs to lead the Chicago Cubs to a 7-0 victory over the St. Louis Cardinals on Friday.
Arrieta (1-0) allowed two hits and struck out seven for his first win with the Cubs.
The hard-throwing right-hander was acquired from the Baltimore Orioles in a July 2 trade.
Before Friday, his only other day on the Cubs' roster was as the 26th man for a doubleheader against Milwaukee on July 30.
The Cubs snapped a four-game losing streak with the win and are 7-7 this season against the Cardinals. St. Louis has dropped six of nine overall.
The Cubs had been shut out in four of their past five home games - a streak dating back to Aug. 3.
