Cubs 4, Orioles 1
CHICAGO — Jake Arrieta shut down his former team, holding the Orioles to four hits over seven innings, and Javier Baez homered for the Cubs. Baez hit his sixth homer in his 18th game since getting called up. Luis Valbuena also homered, and Logan Watkins and Arismendy Alcantara singled in runs as Chicago ended Baltimore's four-game win streak. The Orioles sent Arrieta and reliever Pedro Strop to Chicago last year.
