PHOENIX -- The D-backs got a solid start from rookie Andrew Chafin on Wednesday, but it proved to be for naught. Arizona still dropped the rubber game of its three-game set with the Giants, 4-2, as San Francisco rallied in the ninth inning to steal the game.
With the teams tied at 2 entering the ninth, manager Kirk Gibson turned to closer Addison Reed to potentially give the D-backs a chance to walk off in the bottom half of the inning. Instead, Reed recorded one out and was charged with his sixth loss of the year.
"This is actually his fifth or sixth day either in the game or up [in the bullpen]," Gibson said. "He just didn't have it today."
Like several times this year, Reed's command left him. Half of his 28 pitches were balls, and the lack of control cost him. He walked Pablo Sandoval to start the inning and then walked Brandon Belt to load the bases, giving pinch-hitter Matt Duffy the opportunity to break the game open with a two-run single.
"[Duffy] has that composure you like as a pinch-hitter," Giants manager Bruce Bochy said. "That's not the first time he's gotten a big hit for us. I like him up there in that situation."
Though the Giants scored two off Reed in the ninth, they managed only two against Chafin through the first six innings.
Making his second career start, the southpaw did struggle with his command at times -- he walked four batters -- but he generally limited the damage against a potent Giants lineup.
"I guess you could say maybe I was trying too hard to be too fine and precise with things," Chafin said. "I just went back to going out there and throwing it and trusting things, and that helps a bit."
The D-backs quickly equalized when the Giants did score, and even Chafin got into the offensive mix.
After the Giants opened the scoring in the second with a Brandon Crawford double, the D-backs put a pair of runners on with Chafin coming to the plate. With two outs, Chafin could not sacrifice the runners over, so he was swinging away. The result: a run-scoring single down the first-base line for both his first career hit and RBI.
"It's definitely exciting to go out there and contribute to the offense," Chafin said.
The Giants jumped ahead again in the fifth with a safety squeeze bunt by Gregor Blanco, but the D-backs came back quickly with unlikely means in the bottom half of the inning.
A.J. Pollock tripled on a fly ball to center field, and it looked like he may be stranded there after Mark Trumbo struck out on a ball in the dirt. Trumbo started running down the line, and catcher Andrew Susac threw him out at first -- a fairly conventional play.
But when Susac threw to first, Pollock bolted for home, sliding in safely just ahead of the tag and tying the game at 2.
"Susac kind of just looked at me, but it really didn't look like a real look," Pollock said. "It looked like he was just kind of going through the motions a little bit.
"I didn't have anything to lose there. I was just trying to make something happen. Fortunately, it worked out."
