PHOENIX -- A return home didn't help. The brand new Nike MLB City Connect uniforms with “Serpientes” across the chest didn't change the luck.

Even an outstanding pitching performance by Caleb Smith didn't do the trick.

The D-backs’ losing streak rolled on Friday night at Chase Field, reaching a franchise-record 15 games in a 3-0 loss to the Dodgers.

Arizona has now lost 29 of its last 31 games and 38 of 43.

The D-backs on Thursday set a Major League record by dropping their 23rd straight road game, and manager Torey Lovullo is running out of ways to explain what has happened to his team.

"I'm pissed," Lovullo said. "I don't like it. We've got to find a way out of it. We've got to go out and execute and do the things we're supposed to do the way we know how to do them and get the job done and win a baseball game. That's it."

Smith, who declined to speak to reporters after the game, gave the D-backs a chance to get that win by allowing just one hit over six shutout innings.

"It's exactly what we need on a night where we might have been a tad thin in the bullpen," Lovullo said. "We got six unbelievable innings from Caleb. He fought and clawed for everything that he got today. He was making pitches early in the game, he was making pitches when he had some traffic out there. It was a very good outing for him, and he carried us into that seventh inning with a chance to win a baseball game. He did more than enough today."

Unfortunately for the D-backs, so did Dodgers starter Trevor Bauer, who allowed three hits while throwing seven shutout innings of his own.

The Dodgers finally broke through in the eighth, and it was a familiar face who did the damage. Former D-backs outfielder Steven Souza Jr. hit a homer off Joe Mantiply to spark a three-run rally.

"We threw a pitch where we weren't supposed to and into an area where he can do damage and he did his job," Lovullo said.

Souza, whom the D-backs traded for prior to the 2018 season, was limited by injuries during his time in Arizona. He missed a large chunk of '18 and all of '19 before the D-backs decided to non-tender him prior to '20.

The importance of the homer was evident in the emotion he showed rounding the bases and in the dugout afterward.

“Anytime you play old teams, it's fun to play against and do well against them,” Souza said. “Honestly, the last moment that I had here wasn't a great one, so I was more fired up that I could erase that, put that really in the past and celebrate this one.”

It's been a while since the D-backs have gotten to celebrate much of anything and as the losses pile up, so does the frustration.

"I think we're all getting tired of it," Lovullo said. "The fans are getting tired of it. You guys are getting tired of it. It's time to find a way."

The D-backs put some runners on base early in the game, but Dodgers pitchers retired 13 in a row to end the game.

"Look, we've got to lock it in sometimes," Lovullo said. "We've got to lock it down and just be challenging at-bats or get on the mound and make quality pitches and do the things the way you're supposed to do them."
