Chicago, IL (Sports Network) - Geovany Soto's two-out homer in the eighth proved to be the difference, as the Chicago Cubs opened a three-game series against the Houston Astros with a 5-4 victory at Wrigley Field.
Soto launched his 17th home run of the season and the 10th go-ahead shot of his career, as the Cubs improved to 9-4 under interim manager Mike Quade. Marlon Byrd added a two-run shot, while Jeff Baker and Blake DeWitt each drove in a run in the win.
Casey Coleman allowed four runs, eight hits and five walks in a six-inning start, and Andrew Cashner (2-5) earned the win for a scoreless eighth inning. Carlos Marmol notched his 28th save with a perfect ninth.
Chris Johnson homered for the Astros, who came into this series with 11 wins in their last 14 games. Michael Bourn added two hits and two walks, while Jeff Keppinger and Hunter Pence each drove in a run.
Wandy Rodriguez wasn't involved in the decision after yielding four runs and eight hits while walking one and fanning six in seven innings. Wilton Lopez (5-2) gave up Soto's homer to take the loss.
After Cashner retired the Astros in order to keep the game tied heading to the bottom of the eighth, Soto launched a pitch out of the stadium and onto the streets of Chicago beyond left-center for a 5-4 Cubs lead.
Marmol closed out the game by retiring Bourn, Keppinger and Pence in order.
