SAN FRANCISCO-Things were looking good for the San Francisco Giants in the early going, but it was the top of the seventh inning that proved to be the Achilles heel for them in the end.

A.J. Pollock hit a two-run double that scored Peninsula native Daniel Descalso and Ketel Marte in the top of the seventh inning, as the Arizona Diamondbacks came back to defeat the Giants 3-2 before a crowd of 39,810 at AT&T Park.

The seventh inning comeback made a winner of Robbie Ray, who won his 14th game of the season, as he went seven innings, allowing two runs (one earned), allowing six hits, walking not a batter and striking out 10.

It was a tough loss for Jeff Samardzija, who pitched eight strong innings for the Giants, allowing three runs on six hits, not walking a batter and striking out six. With the loss, Samardzija set a dubious career high with 14 losses.

Samardzija was cruising along after he allowed a double to Chris Herrmann in the top of the second inning, as after that, Samardzija retired the next 14 Diamondbacks in a row until Descalso singled with one out in the top of the seventh inning.

Samardzija helped himself out at the plate in the bottom of the sixth inning, as he led off the inning with a single, went to second on a Joe Panik single and then scored when Ray could not handle a throw on a Hunter Pence single that allowed Panik to advance to third base. Unfortunately, that is where the rally ended, as both Buster Posey and Nick Hundley struck out to end the threat.

Pence was forced to leave the game in the top of the ninth inning, as he suffered back spasms and is listed as day-to-day.

NOTES: Madison Bumgarner looks to even up the series on Saturday night, as he takes the mound against Zack Greinke.

Engelb Vielma was claimed from the Minnesota Twins, and to make room for the 23-year infielder, the Giants moved Michael Morse to the 60-day disabled list to create a spot on the 40-man roster.
