The Padres’ offense didn’t do much of anything for five innings in the middle of Saturday night’s game at Petco Park.

Then they commenced trying to do something they have done quite a bit this season.

They made the game close in the seventh inning and tied it in the eighth before losing 7-5 in extra innings for the first time this season.

The Diamondbacks scored three runs off Wandy Peralta in the 10th. That denied the Padres their 19th victory this season in a game in which they trailed or were tied in the seventh inning or later. Their 18 victories earned that late are the same number they had all last season.

“We’ve done really good,” Jake Cronenworth said after the Padres’ fourth loss in their past 16 games. “We’re not going to let a game where we lose by two runs and had bases loaded in the 10th get us down.”

Padres starter Matt Waldron threw 39 pitches in the second inning and then finished four more innings. He had allowed two runs to that point before being charged with another run in the seventh, when Yuki Matsui allowed an inherited runner and a runner of his own to score.

That gave the Diamondbacks a 4-1 lead, and that’s when the Padres started to convert on opportunities.

The Padres could not make much of all the strikes Diamondbacks starter Brandon Pfaadt threw them and then did nothing against local product Kevin Ginkel before scoring twice off left-hander Joe Mantiply in the bottom of the seventh to get to 4-3.

Ha-Seong Kim began the comeback with a single. He went to second on Kyle Higashioka’s dribbled infield single and to third on a line drive fielder’s choice by Luis Arraez that resulted in Higashioka being out at second.

With runners at the corners, Jurickson Profar lined a double to the left field corner that scored Kim and moved Arraez to third. Jake Cronenworth’s bunt scored Arraez before Manny Machado, who had decided Saturday’s game with a walk-off home run, struck out against new reliever Bryce Jarvis.

Kim tied the game in the eighth with a two-out double off Ryan Thompson, driving in Donovan Solano, who had led off with a double against Jarvis.

Neither team scored in the ninth – not the Diamondbacks against Adrián Morejón nor the Padres against Thompson.

But the Diamondbacks clobbering of Peralta commenced with his ill-advised attempt to make a play on a bunt by Geraldo Perdomo on which third baseman Manny Machado was the only one who had a chance to get the out.

Perdomo’s bunt was perfectly placed, and he might have beat a throw from Machado, but even before he bobbled the ball, Peralta was at a disadvantage since he was running away from first base.

“It was a big play,” a perturbed Mike Shildt said. “We know Perdomo’s gonna bunt. (He) put down a good bunt. Couldn’t make a play. So it opened it up for a bigger inning.”

Peralta then issued a walk to load the bases, and Christian Walker sent a grounder through a drawn-in infield to drive in two runs. Stephen Kolek replaced Peralta and allowed one of the runners he inherited to score while getting three outs.

The Padres came back from one down to win on Machado’s walk-off homer Friday after the bullpen allowed six runs in the top of the ninth.

But after scoring a run on another Solano double and having the bases loaded with no outs in the bottom of the 10th on Saturday, Bryce Johnson struck out against Thyago Vieira and Kim struck out and Kyle Higashioka flied out to left field against Humberto Castellanos.

Machado, who was celebrating his 32nd birthday on Saturday, gave the Padres a 1-0 lead in the first inning.

His broken-bat flare into left field, on an 0-2 count, was the Padres’ third single of the inning and sent  Arraez racing home from second base.

The Padres had scored 10 runs (eight earned) in Pfaadt’s two previous starts against them this season, and it seemed they might be on their way to another big night.

But they could not capitalize on David Peralta’s lead-off single in the second inning nor Jackson Merrill’s one-out single in the fourth.

Through four innings, Pfaadt had thrown strikes on 41 of his 49 pitches (84 percent) and the Diamondbacks led 2-1.

Kim led off the bottom of the fifth with a double off the wall in left-center field before Kyle Higashioka struck out.

Arraez then lined a ball at 98 mph that nailed Pfaadt in the left ankle. The ball bounced well past the third base line — far enough that Kim rounded third full speed before slamming on the brakes and getting back to third when third baseman Eugenio Suárez sprinted over and grabbed the ball.

Pfaadt was replaced by Ginkel. The El Capitan High School and Southwestern College grad struck out Profar and Cronenworth to end the fifth and Machado and Solano to start the fifth before getting Merrill on a lineout.

The Diamondbacks had tied the game during Waldron’s marathon second inning, which just sort of leaked away from him as he threw more pitches than any Padres pitcher had in any inning this season.

The inning began with an infield single by Christian Walker before Gurriel popped out and Brandon McCarthy struck out.

Waldron then walked Suárez, moving Walker to second, before Poway’s Kevin Newman hit a flare off the end of his bat to bring in Walker.A full-count walk to No.9 batter Jose Herrera loaded the bases before Waldron struck out Corbin Carroll with a full-count sweeper at the bottom of the zone and on the inside edge.

Waldron was at 53 pitches. He got through the next two innings on a total of 25 pitches but also allowed a go-ahead homer to Gurriel leading off the fourth.

Waldron was at 89 pitches after six innings but went back out to start the seventh and promptly yielded a single to Suárez. Shildt said he liked the matchup of Waldron against Suárez and was also trying to shorten the game for his beleagured bullpen.

When Suárez got the hit, Shildt went to Matsui.

Matsui surrendered a one-out double by Herrera that brought in a run charged to Waldron and a two-out triple by Geraldo Perdomo that drove in a second run to make it 4-1.

Actor and creator David Dastmalchian will be heading to San Diego Comic-Con again this year.

Dastmalchian confirmed on Instagram that he will be attending the convention. It was in response to a post from his Count Crowley comic book series announcing its return to the convention, which likely signals that Dastmalchian will be on hand to promote it with Dark Horse.

The series follows TV journalist Jerri Bartman, who has returned to her Midwest hometown station, and finds that her new job hosting the nightly Creature Feature comes with a super, supernatural responsibility.

They promote “exciting plans” and news for the convention are incoming.

Dastmalchian’s other upcoming projects, including Apple TV’s Murderbot, likely aren’t far enough along in production. The series follows a sentient security android who must mask the ability of free thought, and stars Alexander Skarsgård and Dastmalchian, but it only started filming in March.

For the struggling San Diego Wave FC, a teenager represents hope.

Melanie Barcenas has magic feet, as verified by her last two matches since returning from a hip injury.

The 16-year-old’s exciting trap-and-shot late in Friday’s match wasn’t enough to end the Wave’s struggles. The goalkeeper knocked away the high-speed shot, and the Portland Thorns broke through for a goal in the 84th minute, leading to the visiting Wave’s 1-0 defeat before an announced crowd of 18,011.

But talent is talent.

It’s clear Barcenas, a Clairemont-area native and former San Diego Surf star, has it.

“Oh, she’s so exciting,” Wave interim coach Paul Buckle said. “It’s not easy coming off the bench for any professional player, but she’s made it look pretty easy.”

Wave defender Hanna Lundkvist says this of Barcenas: “She’s brave and she’s got techniques.”

The Wave are desperate for scoring punch. Look for Barcenas to get more chances beginning Aug. 24, when the National Women’s Soccer League’s regular season resumes following the Paris Olympics.

Plagued by imprecision and disconnection, the 10th-place Wave (3-7-6) have been shut out in their past three-and-half games — including both matches since team president Jill Ellis fired coach Casey Stoney, the defense-first head coach.

Of course, a teen can’t be expected to come to the rescue.

The burden to turn around the offense begins with several veterans, including three accomplished NWSL scorers who are without a goal this season: forwards Alex Morgan, 35, and Maria Sanchez, 28, and midfielder Savannah McCaskill, 27.

Morgan’s drought, which spans 10 matches, appeared to end late in Friday’s first half when she tapped in a loose ball.

Then came a signal from the referee: Morgan was offside.

“That’s how it’s going for us,” said Buckle, who disagreed with the call.

Deep into her second season, Barcenas has shown she might provide a spark during the upcoming 10-game stretch that ends in early November.

She entered in the second half, just as she did in a 3-0 loss a week earlier.

Nearly decking the Thorns, she unloaded perhaps the most powerful shot any opponent has faced in the Wave’s past three matches.

The sequence began when Barcenas, a 5-foot-4 midfielder working at left wing after replacing Sánchez, tamed McCaskill’s smart crossing pass into the box with a perfect first touch. Eluding a defender, Barcenas pivoted and clubbed the bounding ball with her right foot.

Goalkeeper Shelby Hogan, on the way to her seventh shutout this season, punched the laser over the bar.

“Incredible save,” said Buckle.

Two minutes after the fans exhaled, the Thorns had them roaring.

It began with Thorns midfielder Hina Sugita stealing goalkeeper’s Kailen Sheridan’s ill-advised pass by ambushing Wave defender Kristen McNabb near the center stripe.

The sequence ended with 22-year-old Izzy D’Aquila’s one-touch goal from 4 yards, off a crossing pass from Janine Beckie, who saw D’Aquila dart past defenders Abby Dahlkemper and Lundkvist.

The final whistle sent the Wave on a glum, too familiar walk off the pitch.

They’re winless in their nine road matches, a year after winning six road games to record the league’s best away record.

Scoreless in the 300-plus minutes since rookie Mya Jones’ goal at NJ/NY Gotham FC on June 19, winless in the nine matches since they beat last-place Utah on May 8 in Mission Valley, the Wave now will try to regroup.

The layoff and exhibition matches will allow them to work on the finer points of the transition from a defense-first team to one that, in Ellis’ phrase, is “built on attacking.”

Such an overhaul takes more than two weeks.

“We have to keep believing because we did so many things right,” Buckle said. ‘We were brave again. But, we’re just not getting anything for our troubles right now. We were brave with the ball. I’d be nitpicking if I said anything different.

“I’m just desperately disappointed for the players. I said that to them, ‘Football can be cruel sometimes’. But, if we keep playing like we’re playing, it will turn. It will turn for us.”

In pursuit of a playoff bid, NWSL teams are permitted more lives than a cat. Eight of the 14 clubs get in.

Every soccer expert agrees the Wave have more talent – especially on defense led by Naomi Girma – than a handful of fellow stragglers.

All it may take is a two or three wins and a few ties. Six of the 10 matches will come in Mission Valley. Rest will be abundant, and several upcoming opponents lack game-changing firepower.

But it will take more scoring from a Wave team that shows 12 goals in 16 matches.

The Wave know the stakes. They stand as the NWSL’s most disappointing team, given they won the league title last year and were picked first or second by the soccer media and oddsmakers entering this year.

“There’s nothing to say,” said Lundkvist, who was in Sweden last season. “We have to keep going and just keep pushing.”
