The Diamondbacks hit the field against the Padres with the trade deadline still hanging over everything, and that uncertainty is baked right into the series preview. By the time this matchup is played, the roster could already look different. Mike Hazen and AJ Preller could change the picture at any moment, even before anything is officially out there.
For now, Arizona enters the series in a much better place than it was a year ago. Last season, the Diamondbacks were swept in Detroit heading into the deadline.
This time, they’ve won four of their last five series, sit tied for the second Wild Card, and are six games over .500. They’ve done it while dealing with arguably more injuries, which makes the run even more notable.
The opponent makes this a meaningful stretch. San Diego is only one game back of Arizona in the Wild Card standings, so this series has immediate consequences.
If the Padres take it, they gain a little breathing room. If they lose, they could be pushed out of a playoff spot after all the work they’ve done to get there.
Game 1 on 8/3 at 6:40 PM features Brandon Pfaadt against Michael King. Pfaadt is 5-1 with a 4.00 ERA, 107 ERA+, 1.29 WHIP, and 0.6 bWAR.
He’s crossed into the over-100 ERA+ club since the last time this matchup was previewed, and the turnaround has come through a run of strong starts since returning to the rotation. In six starts, he hasn’t allowed more than two runs in any outing, hasn’t gone fewer than five innings, and most recently tossed seven scoreless innings against the Pirates.
The team believed he was tipping pitches, which is why he was sent down to work on it, and the results have backed that up. That extension he signed looks a lot better now than it did two months ago.
King comes in at 6-7 with a 3.38 ERA, 121 ERA+, 1.17 WHIP, and 2.8 bWAR. He’s been a steady arm for San Diego since they acquired him in 2024, posting a 129 ERA+ over the last 2.5 seasons.
This year has followed that same pattern, with two runs or fewer allowed in five of his last seven starts. Still, Arizona has a reason to feel decent about the matchup after King gave up four runs to the Rockies in San Diego in his last outing.
There’s also a recent stretch in which he allowed four or more runs in three straight starts at the end of May and the beginning of June.
On 8/4 at 6:40 PM, Eduardo Rodriguez is scheduled to start for Arizona against a TBD opponent. Rodriguez is 10-3 with a 2.48 ERA, 172 ERA+, 1.20 WHIP, and 4.5 bWAR, and he’s coming off eight scoreless innings against the Pirates.
At this point, there’s not much left to say that hasn’t already been said about him, and that’s because he keeps delivering. If the Diamondbacks finish strong, he figures to be a major reason why.
Game 3 on 8/5 at 6:40 brings Mitch Bratt, who is 0-1 with a 5.23 ERA, 83 ERA+, 1.83 WHIP, and 0.0 bWAR, into a matchup with a TBD starter. Bratt has now made five big league starts, and the ride has been uneven.
He’s gone five innings in back-to-back outings, but the results were all over the place: one was a five-run, five-walk mess, and the other was a one-run effort that still included four walks. His 6.77 FIP only reinforces the concern.
Kohl Drake gets the ball in Game 4 on 8/6 at 6:4o against Walker Buehler. Drake is 0-0 with a 4.85 ERA, 90 ERA+, 1.46 WHIP, and 0.0 bWAR.
His MLB start has been fairly ordinary so far: two decent but short outings and one rough one. The bigger issue is that his FIP is another run higher than his ERA.
On the plus side, he’s been a nice boost for the offense, because he hasn’t received fewer than six runs of support in any of his starts.
Buehler, meanwhile, is 6-5 with a 5.18 ERA, 79 ERA+, 1.44 WHIP, and 0.1 bWAR. His arc has gone a long way from the days when he was being talked about as the next big thing and showing up in Cy Young Award top tens.
He hasn’t posted a season over 100 ERA+ since 2022, and he’s only had one over 80 in that span. This year has followed the same pattern, with short outings and multiple runs allowed.
When he faced the Diamondbacks on July 6, he gave up seven runs in five innings, struck out four, and walked one.
It’s tough to pin down a final read on the series with the deadline still looming and possible roster changes still in play. The rotation could look different by the time these games are actually played. Still, Arizona’s offense has started to wake up, and with Pfaadt opening the series, the Diamondbacks have a shot to start on the right foot.

Diamondbacks Send A Clear Message With Latest Padres Lineup Shift
The Diamondbacks lineup for their game against the Padres came with a couple of notable absences, as Ketel Marte and Nolan Arenado were both set for scheduled rest days. It was the kind of midseason adjustment that signals more than simple maintenance, especially with Arizona juggling roster decisions around the active roster and the catching situation, where Gabriel Moreno returned and Del Castillo was optioned.
There was also movement on the pitching side, with Ryan Thompson shifted after a sharp post-break slump, another reminder that the club is not waiting around for performance to stabilize on its own. Against a Padres lineup that put Lars Nootbaar at the top against right-hander Casey Mize, Arizonas approach looked like a clear attempt to keep the group fresh, responsive and a little less predictable as the stretch run takes shape.

Diamondbacks Deadline Leaves One Big Question For Arizonas Wild Card Push
The Diamondbacks entered deadline week with a real chance to reinforce a club still hanging around the postseason picture, but the biggest move they made was bringing in Lars Nootbaar from the Cardinals. Arizona sent Daniel Eagen, Sandro Santana and a player to be named later to St. Louis for the outfielder, a swap that gives the roster another option in the outfield but stopped short of the sort of overhaul many around the team expected.
What made the deadline feel unfinished was how little else changed for a club that still had obvious needs. The Athletics D+ grade reflected that unease, and general manager Mike Hazen did not try to hide his own frustration afterward, saying he wished more could have been done before the deadline. For a team trying to keep its wild-card push alive, the question now is whether this was enough or just the start of a longer fix. [Read more 🡒]
Diamondbacks Rookies Are Making Mike Hazens Pitching Gamble Look Real
The Diamondbacks latest win offered another reminder that their pitching staff is being held together by some of the youngest arms on the roster. In a 10-4 victory over the Padres at Chase Field, rookie left-hander Mitch Bratt outperformed San Diegos Casey Mize, who was chased in the fourth inning after allowing multiple hits and runs. For Arizona, the bigger takeaway was the same one hovering over the club for much of the stretch run: the rotation has become a place where rookies are not just filling innings, but keeping the team afloat.
Bratt and Kohl Drake have been part of that answer because injuries have thinned out the veteran options Mike Hazen would rather lean on. It is a calculated gamble, and one that has looked increasingly real as the Diamondbacks keep leaning on those inexperienced starters in meaningful games. The larger question now is how long Arizona can keep asking that kind of load from a pair of rookies, even as the results continue to buy them time. [Read more 🡒]
