What D-backs Brutal Dodger Stadium Sweep Told Us

The Arizona Diamondbacks were swept out of Dodger Stadium in extremely ugly fashion to begin the 2026 season. It was not the note on which Arizona hoped to begin their 162-game campaign.

In the grand scheme of a regular season, three games is nothing to dwell too heavily on. But there were some aspects of the unfortunate sweep that could be learned from — and some that raised even further questions about the viability of this team.

What we learned — and didn't learn — from Arizona's brutal three-game opening series sweep.

What we learned from Diamondbacks' sweep by Dodgers

1: Geraldo Perdomo looks regression-proof

It's very early, and it's going to be difficult to imagine Geraldo Perdomo posting another seven-WAR season when 2026 is all said and done, but Perdomo is not showing signs of taking a significant step back right away.

The star shortstop went 4-for-12 at the plate with a double and a two-run homer, with just two strikeouts in three games. His patented ability to work counts hasn't disappeared, and his defense even looked a little sharper.

It's early, but Arizona's rising star doesn't appear to be headed for a massive regression early on.

2: Diamondbacks' defensive upgrades are real

The Diamondbacks put an emphasis on improving their infield defense, and it's showing.

Nolan Arenado has looked every part of the six-time Platinum Glove winner at the hot corner, and Carlos Santana — despite being charged with an error on Saturday night — is a more competent first base defender.

Ketel Marte and Perdomo both look quicker and more agile at their respective positions, as well.

That won't necessarily help when balls are leaving the yard, but it's a step in the right direction for an area that was surprisingly deficient in 2025.

What we didn't learn from Diamondbacks' sweep at Dodgers

1: Just how much of a pitching problem do D-backs have?

Arizona's pitching staff had an extremely uneven performance against a team that is difficult to make assessments with. The Dodgers lineup can batter even the top staffs in baseball.

Zac Gallen looked like a renewed pitcher, until one mistake bit him. Ryne Nelson looked dominant, until the same thing happened. Eduardo Rodriguez shut L.A. down entirely for five innings.

And surprisingly enough, the D-backs' bullpen has not been as poor as one might think. Outside of the blowup inning by Taylor Clarke in game one, the D-backs relief corps gave up three runs in 10 innings — certainly not a terrible result against an All-Star-filled lineup.

But they also coughed up leads in back-to-back games. The overall output may not have been as bad as it could have, but the timing was as bad as possible. The question will be how this under-constructed unit can perform against less-proficient offenses.

2: Can the D-backs' offense produce down the order?

There is nothing wrong with Marte, Carroll and Perdomo. Even Gabriel Moreno looked solid enough at the plate.

But the D-backs offense ran into a black hole just below the top four. Arenado and Santana are both off to rough starts, coming off rough seasons. Both have just one hit, with a good deal of chase, swing-and-miss and weak contact.

That comes with the territory of emphasizing defense sometimes. It can be a trade-off. But Arizona can't put the entire offensive burden on their star trio.

With that said, both Alek Thomas and Jordan Lawlar look like they could be bottom-order contributors. Thomas has two doubles so far, and crushed two 100 MPH batted balls that went for outs in game three. Lawlar doubled off a tough right-hander, and even Jorge Barrosa put up some solid at-bats.

But Arizona isn't going to be able to win games scoring only from the top of their order. They need some of their defensive veterans to get on the board.
