CHICAGO

Tsuyoshi Wada earned his first big league win, pitching seven strong innings Monday night, as the Chicago Cubs defeated the Colorado Rockies 4-1.

Anthony Rizzo drove in two runs to back Wada (1-1).

In only his third career start in the majors, Wada cut through the Colorado lineup, allowing one run and five hits. It was a far cry from his last outing, when he lasted four innings and gave up five runs in a loss to San Diego.

The sole blemish on Wada’s performance came in the sixth when the Rockies got three hits, capped by Nolan Arenado’s RBI single.

The 33-year-old Wada won 107 games over nine seasons in Japan.

Pedro Strop worked out of a jam in the eighth inning, and Hector Rondon worked a perfect ninth for his 13th save in 16 chances.

Yohan Flande (0-3) struck out eight in 6 2/3 innings. Those were his career bests in his fifth start.

The Cubs put together two runs in the fourth. Emilio Bonifacio led off with a single, and Arismendy Alcantara doubled, setting up Rizzo’s RBI grounder and Justin Ruggiano’s sacrifice fly.

Chicago added two more runs in the eighth against Nick Masset. John Baker scored on an errant pickoff throw, and Rizzo singled for his 58th RBI this season.
