PHOENIX (AP) — The San Francisco Giants still have time to catch the Los Angeles Dodgers in the NL West.They will have to get better at closing out one-run games if they’re going to get there.Chris Heston pitched effectively into the fifth inning, but the Giants missed numerous opportunities and scored their only run on a wild pitch in a 2-1 loss to the Arizona Diamondbacks on Wednesday.It was San Francisco’s 11th loss in its past 12 one-run games and 17th of the season.“We had a pretty good opportunity but we just couldn’t get a hit,” Giants manager Bruce Bochy. “The one run that we got was on a wild pitch and that is not going to work.”That opportunity came in the seventh inning, when Arizona manager Chip Hale decided to intentionally walk Buster Posey with runners on the corners.It worked out well for the Diamondbacks.Instead of facing Posey, the NL’s third-leading hitter at .329, he opted to have Randall Delgado walk him and pitch to Angel Pagan.Pagan had some previous success against Delgado, but Arizona’s right-hander came through with the biggest out of the game, inducing an inning-ending pop-up to shallow left field.“Posey is one of the best in baseball and in this stadium he’s lights out,” Hale said. “We were willing to take our chances with Angel and move on.”Zack Godley (5-1) was sharp in his last start before heading to the bullpen, allowing a run on three hits in six innings.Jarrod Saltalamacchia homered for the second straight game, a two-run shot off Heston (11-10), and Ender Inciarte had three hits.
