PHOENIX, July 6 \u2014 Riding a two-run game-tying pinch-homer in the top of the eighth by Darin Ruf and a three-run ninth, capped by a two-run double by Austin Slater, the San Francisco Giants<\/a> rallied from a 4\u20130 deficit to defeat the Arizona Diamondbacks<\/a>, 7\u20135, Wednesday evening. The victory allowed the Giants to avoid a three-game sweep. It also wiped out a valiant two-run, two-hit start by Diamondbacks righty Merrill Kelly, who had outdueled Giants righty Alex Cobb.<\/p>\n The Diamondbacks took an early lead in the bottom of the first. It started with a two-out double by designated hitter Ketel Marte. After first baseman Christian Walker\u2026er, walked, left fielder David Peralta singled Marte home. It became a four-run game in the bottom of the second. Second baseman Buddy Kennedy led off with a single but was retired on a 6-5 force play at second. The runner taking his place, shortstop Geraldo Perdomo, advanced to third on a single by catcher Jose Herrera. A double to right by third baseman Josh Rojas scored Perdomo and advanced Herrera to third. Both Herrera and Rojas scored when center fielder Alek Thomas followed with a single.<\/p>\n The Giants got on the board in the top of the fifth. It initially looked like it came in the form of a three-run home run by catcher Joey Bart that would have scored shortstop Brandon Crawford and second baseman Tommy La Stella. However, a crew chief-initiated replay review led to a fan interference ruling, giving Bart a double. \u201cShout out to that fan for catching that ball and not making it a homer,\u201d Kelly joked after the game. \u201cThat one definitely helped out a bunch. (Bart) put a good swing on that ball.\u201d<\/p>\n Crawford, who had reached with a double, still scored. However, La Stella \u2014 who reached on a walk \u2014 had to stop at third. Right fielder LaMonte Wade Jr. followed with a grounder to short. Bart, who had already started toward third, got caught in a rundown for the second out. However, Wade\u2019s grounder brought La Stella in from third, making the score 4\u20132 in favor of the Diamondbacks.<\/p>\n In the top of the eighth, left-handed reliever Joe Mantiply took the hill. He had 31 scoreless outings out of his 33 total relief appearances at that point \u2014 a National League-leading 93.9%. It was not to be this time around. After a bunt single by pinch-hitter Austin Slater \u2014 initially ruled out but corrected after replay review \u2014 pinch-hitter Darin Ruf belted a 429-foot game-tying homer into the left-field seats.<\/p>\nGiants Chip Away at Diamondbacks Lead<\/h3>\n
