Giants give up 13 runs in fifth, fall to Rockies 17-7

SAN FRANCISCO - Nolan Arenado and Trevor Story each homered and drove in three runs, and the Colorado Rockies set a franchise record with a 13-run fifth inning in a 17-7 victory over the San Francisco Giants on Thursday night.

Gerardo Parra had two hits and three RBIs in the fifth, when Colorado sent 17 batters to the plate.

It’s the most runs scored in an inning by any team since Arizona scored 13 in the fourth against Pittsburgh on April 11, 2010.

Every Rockies hitter either scored or drove in a run in the inning, including starting pitcher Chris Rusin, who singled home a pair of runs. Seven of the nine did both.

Matt Cain (0-4) lost his first four decisions in a season for the first time in his career. He allowed eight runs on 10 hits in four-plus innings and did not walk a batter or strike out anyone. Reliever Vin Mazzaro yielded nine runs on six hits while recording just one out.

D.J. LeMahieu collected three hits and drove in a run, Tony Wolters drove in two runs and the Rockies won their fifth in seven games following a season-worst, five-game losing streak. Mark Reynolds also had a pair of RBIs.

Rusin had a 14? innings scoreless streak come to an end, though Colorado’s big fifth made it a moot point.

Rusin gave up seven runs on 13 hits in his 4? innings. He walked two and struck out four. Despite leaving with a 10-run advantage, he was not eligible for the win because he failed to finish the fifth.

The Giants rallied for four runs in the bottom of the fifth, with Rusin taken out after giving up a two-run single to Gregor Blanco.

Christian Bergman (1-3) came on to throw 2? scoreless innings, striking out three, to get credit for the win.

Buster Posey had two hits and drove in two. Matt Duffy collected three hits, Denard Span doubled twice, singled and drove in a run. Brandon Crawford and Mac Williamson also had RBIs.
