SAN FRANCISCO -- Anybody doubting that there’s life left in the Pirates needed to check out Monday night’s ninth inning.

Pittsburgh tormented three Giants relievers in the ninth by scoring four runs to overcome a two-run deficit and surge to a 6-4 triumph at Oracle Park.

Kevin Newman and Bryan Reynolds, who have taken their place among baseball’s best 1-2 combinations at the top of the order, combined to drive in three of the runs that spurred the Pirates’ reversal.

“They like to hit and they like to play baseball,” Pirates manager Clint Hurdle said. “I think the combination of the two has them getting the results they’ve been getting.”

The Pirates recorded their seventh victory in 11 games and 11th in their last 17.

“It’s fun to watch the entire team fight,” Hurdle said. “Our team’s been fun to watch and hard to watch sometimes because we can break your heart and we can make you jump up and down. This isn’t the first time we’ve done this.”

The Giants entered the ninth inning leading, 4-2. The situation normally would have called for closer Will Smith, but the All-Star left-hander was unavailable due to back soreness. Pittsburgh took full advantage of his absence.

Pinch-hitter Kevin Kramer’s single off Tyler Rogers began the rally. 

“He’s a guy that’s always been an offensive player, and he showed up tonight,” Hurdle said of Kramer. 

The comeback resumed one out later when Fernando Abad walked Josh Bell. Then came Elias Diaz, the inning’s third pinch-hitter, who roped a drive to left-center field. Mike Yastrzemski couldn’t make the catch, but the baserunners weren’t certain that the ball was loose. Ultimately, Diaz recorded a single that loaded the bases.

Newman singled home two runs to tie the score before Reynolds, the former Giants prospect, singled home another run. Jose Osuna launched a sacrifice fly to conclude the outburst.

Newman is batting .429 (24-for-56) while hitting safely in 13 of his last 14 games. Reynolds, who tied Paul Waner’s 93-year-old franchise record for doubles by a rookie by hitting his 35th in the sixth inning, recorded his 11th game-winning hit.

Pittsburgh received another encouraging effort from starter Trevor Williams, whose statistical line was deceiving. He yielded eight hits and all of San Francisco’s four runs in 5 2/3 innings, ending his streak of three consecutive quality starts. But the outing didn’t necessarily break his momentum. A handful of the hits he allowed barely cleared the infield.

So for Williams, who’s still trying to re-establish himself after spending a month of the first half on the injured list, to endure a “subpar” outing such as this was encouraging.

“He only made less than a handful of mistakes today,” Hurdle said. “The line looks the way the line looks, but it was a blue-collar effort from him. … He was able to compete without his best stuff tonight.”

Competing against Madison Bumgarner was a treat for Williams, who was thrilled to share the mound with the Giants’ highly regarded ace.

“The grandeur is still there,” Williams said. “I had this game circled as soon as I found out I was pitching against him. You wake up knowing you’re going to face off against one of the greats.”

Thus, it scarcely bothered Williams when Bumgarner struck him out in the third inning.

“It was an honor to get diced up by him,” Williams said.
