Birthday boy Ryan O'Hearn leads Pirates past Cubs

Ryan O'Hearn celebrated his 32nd birthday by belting his second grand slam of the season and fourth of his career as the host Pittsburgh Pirates held on for an 8-7 victory over the Chicago Cubs on Sunday.

Pittsburgh's Shawn Ross launched a two-run homer in his second MLB game while rookie Esmerlyn Valdez also went deep and added an RBI single

Brandon Lowe collected three hits and two runs as the Pirates snapped a three-game losing streak in the finale of the three-game series.

The offensive explosion proved just enough for Braxton Ashcraft (10-4), who allowed four runs on seven hits in six innings.

Carmen Mlodzinski bridged the gap to Mason Montgomery, who surrendered Seiya Suzuki's two-run homer in the ninth before retiring the next two batters to secure his second save.

Pete Crow-Armstrong ripped an RBI triple and Dansby Swanson, Nico Hoerner and Pedro Ramirez each had an RBI single for the Cubs.

Swanson opened the scoring in the second with an RBI single, but that slim advantage didn't last long.

Valdez sent a 1-1 cutter from Jameson Taillon (2-6) over the left center wall to lead off the second inning. Valdez's homer was his 14th of the season and eighth in his last 13 games. After O'Hearn walked, Ross deposited a 3-2 cutter over the wall in left.

The Pirates loaded the bases in the third before O'Hearn deposited a 0-1 fastball from Taillon over the wall in center to stake his team to a 7-1 lead. The homer by O'Hearn was his 17th of the season and first since he went deep three times -- highlighted by a grand slam -- in a 12-4 victory over the Atlanta Braves on July 7.

Taillon permitted seven runs on six hits in four innings to fall to 0-5 in his last eight outings.

Chicago scored three times in the fourth before Valdez's broken-bat RBI single off Ryan Rolison extended Pittsburgh's advantage to 8-5 in the fifth.
