PHOENIX -- Ranger Suárez is back, and the Phillies are back to .500.

“Let’s hope we get above it and don’t look back this time,” Phillies catcher J.T. Realmuto said.

Suárez dazzled in Wednesday night’s 4-3 victory over Arizona in 10 innings at Chase Field, moving the Phillies (34-34) to .500 for the first time since May 14. Suarez pitched seven scoreless innings, striking out seven and walking two. He looked like the cool customer that baffled the Braves, Padres and Astros in the postseason, whether he was starting or pitching out of the bullpen.

“When he’s on like that, he can do so many things,” said Realmuto, whose home run in the sixth had the Phillies up, 3-0. “He goes through the lineup multiple times so well because he can get guys out in different ways. Every at-bat, he’s using different pitches, different sides of the plate. He’s got four, five plus-quality pitches that he can control on both sides of the plate. When you can do that, it’s real fun to navigate the lineup.”

Suárez is 2-1 with a 1.35 ERA in his last four starts. He has the fourth-best ERA in baseball from May 30 through Wednesday (minimum 13 1/3 innings pitched):

• Blake Snell, 0.47 ERA (one earned run, 19 innings)
• Jon Gray, 0.56 ERA (one earned runs, 16 innings)
• José Berrios, 0.99 ERA (three earned runs, 27 1/3 innings)
• Suárez, 1.35 ERA (four earned runs, 26 2/3 innings)

Suárez started the season on the 15-day injured list because of a strained left elbow. He made three rehab appearances before the Phillies activated him on May 13. He had a 9.82 ERA in his first three starts.

Phillies manager Rob Thomson said those first three starts could be considered his final three in a traditional Spring Training, but the Phillies brought Suárez back when they did because they needed him.

Suárez is giving them everything they need and more right now. So is the rest of the rotation. It has a 1.71 ERA in the Phillies’ current 9-2 run.

“What I liked the most is that I attacked hitters early, so I was ahead in the count a lot,” Suárez said through the team’s interpreter. “I induced a lot of weak contact. That was really good for me.”

Suárez also got a career-high seven swings and misses on his curveball. He had never had more than five.

“The first couple outings, I didn’t throw it too much, but I’ve built more confidence throwing that pitch,” Suárez said. “It’s obviously helping me.”

The Phillies blew a three-run lead in the eighth inning when Seranthony Domínguez got into trouble before allowing a game-tying, two-out, three-run home run to Christian Walker. A collision in left-center field between Kyle Schwarber and Brandon Marsh in the ninth put the potential winning run on second base with two outs, but Craig Kimbrel struck out Emmanuel Rivera to send the game to extra innings.

D-backs right fielder Jake McCarthy and second baseman Geraldo Perdomo collided on Trea Turner’s one-out pop fly in shallow right field in the 10th. The ball fell, allowing Marsh to advance to third and Turner to reach second. Nick Castellanos followed with a sacrifice fly to give the Phillies the lead on a ball that would have been the third out had the D-backs made the play on Turner’s blooper.

José Alvarado closed it out. He threw 16 pitches at 100 mph or more -- two at a season-high 101.6 mph.

“He was a little amped up,” Realmuto said.

The Phillies can move a game over .500 with a victory in Thursday afternoon’s series finale.

“We’re too good of a baseball team to stay below .500 for too long,” Realmuto said. “It’s nice to be back there, but there’s obviously a ton of season left. We’re playing really good baseball right now, but we still have our best baseball ahead of us.”
