Cubs get 13-9 comeback victory over Pirates

Anthony Rizzo’s first career grand slam was part of his first multi-homer game and best-ever six RBI in the Cubs’ 13-9 comeback victory Sunday against the Pittsburgh Pirates.

Rizzo’s 13th and 14th homers of the season were two of three homers by Cubs, the other Joe Mather’s fifth of the season.

It was the first time a Cub has had six RBI in a game since Aramis Ramirez had six against the Houston Astros on July 20, 2010.

The victory was another blow to the Pirates’ hopes of securing a National League wild card spot, but it helped the Cubs lower their “magic number” to avoid 100 losses to five.

The marathon four-hour game saw each team use seven pitchers.

Alfonso Soriano drove in his 100th and 101st RBI of the season in a 3-for-5 game. It’s the third time in Soriano’s career to drive in at least 100 runs and the first since 2005 when he had a career-best 104 with the Texas Rangers.
