PHILADELPHIA -- The Phillies have eight more games to see everything they need to see from their bullpen.

It is enough time that they promoted their No. 7 prospect Orion Kerkering before Friday night’s 5-4 victory over the Mets in 10 innings at Citizens Bank Park. Kerkering might have gotten a look had the game gone a few more innings, but Alec Bohm’s walk-off single over the head of Mets first baseman Mark Vientos in the 10th scored Trea Turner from second base to win it. It was Bohm’s third walk-off hit of the season. It was his second big hit in the past month after a pitcher intentionally walked Bryce Harper to face him.

Bohm took no offense.

“Everybody in the stadium knows they’re going to do that,” Bohm said. “You have to.”

• Games remaining (8): vs. NYM (2), vs. PIT (3), at NYM (3)
• Standings update: The Phillies (85-69) have a four-game lead over the D-backs (81-73) for the top National League Wild Card spot.
• Magic number: 3

The win gave the Phillies a four-game lead over Arizona for the No. 1 spot in the NL Wild Card. If the Phils finish just 4-4, the D-backs cannot catch them in the standings because the Phils own the season tiebreaker.

Phillies right-hander Taijuan Walker allowed two runs in six innings. J.T. Realmuto’s three-run homer in the bottom of the sixth gave the Phillies a 3-2 lead.

Then the Phillies went to their bullpen, which has been a weapon for much of the season, but hasn’t been as effective in recent weeks. Phillies left-hander Matt Strahm pitched a scoreless seventh. He saved the Phillies earlier this season as a starter. Since then, he has been equally as effective pitching in relief opportunities of varying length. In 29 appearances of one or fewer innings, he has a 2.39 ERA, striking out 32 and walking seven in 26 1/3 innings. In 15 appearances of more than one inning, he has a 2.70 ERA, striking out 32 and walking five in 26 2/3 innings.

Left-hander Gregory Soto gave up a homer to Francisco Lindor in the eighth to cut the Phillies lead to 4-3. Right-handers are batting .268 with a .755 OPS this season against Soto, compared to left-handers, who are batting .118 with a .414 OPS.

“He’s going to have to get righties out, because they’re not going to have three lefties in the lineup in a row,” Phillies manager Rob Thomson said. “If they do, they’re going to pinch hit. But I thought he threw the ball well. He made one bad pitch. They were trying to bounce the breaking ball and he just left it up. … He got burned, but I thought he threw the ball well.”

Jeff Hoffman picked up the final out in the eighth. It was his first time pitching three consecutive days this season. Craig Kimbrel pitched for the third consecutive day for the first time, too. He allowed a game-tying homer to Brett Baty in the ninth.

“I think there are some boxes you want to check coming down the stretch and Kimbrel going three days in a row is one of them,” Thomson said. “And this is a good time to do it because his workload wasn’t all that much. Hoffman going three days in a row [as well]. He only threw three pitches yesterday, and one pitch today, so it was probably a good time to do it.”

But perhaps the biggest box to be checked is Seranthony Domínguez.

What exactly will Domínguez give them in the postseason? Kerkering’s promotion has already added one question mark. The Phillies hope that Kerkering could make the postseason roster and become another high-leverage pitcher, if he shows well in the season’s final eight games.

Domínguez is 5-5 with a 3.94 ERA in 55 appearances this season. He has struck out 46 and walked 21 in 48 innings. He has the lowest strikeout rate --20.7 percent -- of his career.

Domínguez recorded the first out in the 10th, then walked Brandon Nimmo. He struck out Lindor swinging on a 3-2 slider for the second out. Domínguez then walked Jeff McNeil to load the bases. He got Alonso to strike out swinging on a 2-2 slider to end the inning.

“He didn’t cave,” Thomson said. “He just kept coming. He kept grinding and he kept battling and I’m happy with it. He got some funky swings on the slider. He kept battling and that’s what we needed him to do.”

Maybe two big strikeouts against two good hitters gets Domínguez jumpstarted.

“I’ve been struggling,” he said. “I’ve got to keep going. This makes me feel better. This makes me feel like I can help the team. I’ve been working all year long so I’m ready when they need me.”
