DENVER - Jeff Samardzija pitched effectively into the eighth inning and Anthony Rizzo doubled home the go-ahead run in the seventh, leading the Chicago Cubs past the Colorado Rockies 3-1 Friday night.
Alfonso Soriano added a home run, his 17th, and Junior Lake, recalled by Chicago from Triple-A Iowa before the game, had three hits in his major league debut, including a double in his first career at-bat. Darwin Barney drove in an insurance run with a ninth-inning double.
Samardzija (6-9) kept the Rockies in check by limiting them to one run on four hits in 7 1-3 innings. He walked three and struck out six.
D.J. LeMahieu doubled off Kevin Gregg to start the ninth and advanced to third on a ground out by Carlos Gonzalez. Troy Tulowitzki walked before Gregg induced Michael Cuddyer to ground into a game-ending double play for his 18th save in 20 chances.
