PHOENIX -- Zac Gallen had looked at his pitch count and done the math. Even before Manny Machado’s base hit landed in the outfield grass with one out in the seventh inning, the D-backs’ rookie knew that he wasn’t going to be able to throw a no-hitter Wednesday night.

Ketel Marte made sure that while Gallen left without the no-hitter, he still got the win as Marte delivered a grand slam in the bottom of the seventh that propelled the D-backs to 4-1 win and a sweep of the Padres.

“Zac has been great for us,” outfielder Jarrod Dyson said. “He’s been doing a phenomenal job. The bullpen has been backing us up. It’s been all around with the offense and the pitching. We look forward to continuing that.”

With the win, their ninth in their last 10 games, the D-backs pulled into a tie with the Phillies, three games behind the Cubs for the second National League Wild Card with 22 games left to play.

“The energy is live in here,” Dyson said. “The guys come in expecting to win. We go out there and apply pressure.”

Gallen, who the D-backs acquired from the Marlins at the Trade Deadline, was on top of his game from the get-go.

Through 6 1/3 innings, he allowed one walk and hit a batter. One other had reached on an error by Wilmer Flores, but Gallen had still only faced one over the minimum since two of the runners were erased on double plays and the other was caught stealing.

“I mean, every time I go out there -- every batter I face -- I’m trying not to give up a hit,” Gallen said. “I took a look at the pitch count and I knew it probably wasn’t going to be possible with where that pitch count was. Just tried to keep it going as long as I could.”

As Gallen continued to pile up the outs and pitches, D-backs manager Torey Lovullo began to get a little anxious.

Gallen finished with 103 pitches and there was no way Lovullo was going to let a young, still-developing pitcher throw many more than that.

It wouldn’t have been the first time this year that Gallen had to exit a no-hitter due to pitch count. He threw seven no-hit innings on Opening Day this year for Triple-A New Orleans but was removed after 87 pitches.

“I was probably the most nervous guy in the stadium because I was trying to figure out how I was going to take him out of a game if he had a certain pitch count,” Lovullo said.

Machado’s hit didn’t seem to faze Gallen, as he struck out the next two hitters to end the frame.

“I knew it was still a 0-0 ballgame, so I’m trying not to let that get to me that much. I still had pitches to make. I didn’t feel like it kind of took me out of the game. I just kind of wanted to lock in even more. That was the goal. It worked out,” Gallen said.

The D-backs then loaded the bases against reliever Craig Stammen in the bottom of the seventh before Marte unloaded them against Luis Perdomo.

Marte now has 30 homers and 85 RBIs. His previous high for home runs in a season came last year with 14, when he drove in 59 runs.

“When I got to 20 [homers], I was thinking I could get 30 as long as I kept coming to the ballpark, worked hard every day, went to the gym and did my routine,” Marte said. “I feel stronger. I’m still looking for more.”

So too are the D-backs, who believe they are coming together at just the right time of the year.

“We’re close [to the Wild Card],” Marte said. “We’re playing good baseball now. I keep saying, we’ve got good talent here. We’ve got a good team.”
