Padres grade: B
Miller is no doubt a great talent, and Sears is a consistent source of innings. For now, the Padres' staff looks positively loaded, but the key words in this sentence are "for now" -- because this move was probably as much about payroll as talent. The Padres can prove me wrong by continuing to add, but this doesn't feel like a typical "A.J. Preller going for it" situation.
Miller has been one of baseball's most electric closers since being shifted to the back of the Athletics' bullpen early last year. He might be the best reliever to move at the deadline, surpassing Ryan Helsley and Jhoan Duran, though we can debate that later. But from a pure roster need, this trade accomplishes nothing for the 2025 Padres. Worse, possible deals to come involving
Robert Suarez and
Dylan Cease could mean Preller's deadline machinations prove to be a short-term net negative for a team with firm grip on a wild-card slot and the talent to go deep in the playoffs.
San Diego's bullpen has been the best in baseball all season. Based on my rankings that rate relievers on game-by-game win probability results, the Padres have the top overall relief staff and four of the top nine individual relievers, including Suarez (No. 1),
Adrian Morejon (3),
Jason Adam (8) and
Jeremiah Estrada(9). Miller ranks 30th, but after a slump earlier in the season, he has been hot of late.
Miller and Sears are both pre-arbitration and so don't cost anything. If the Padres kept everyone intact, the staff would be a beast come October. And it might be anyway, but the savings that would come from moving Suarez and Cease might be enough to get San Diego under the second tax threshold. Even if that doesn't happen, Cease is in a walk year for sure, and Suarez, who can opt out, likely is as well, as he looks to cash in on his strong season. So even if Preller deals that duo, he is still coming out ahead in terms of net controllable years.
But that doesn't mean the Padres come out ahead in either short-term or future value. For this season, Miller plus Sears is likely a lesser combination than Suarez plus Cease. That's rough if that's how it turns out. And longer term, to make this deal, Preller has again pillaged his minor league system, giving up a truly elite talent in Leo De Vries (preseason No. 15 by ESPN's Kiley McDaniel and current No. 3 by MLB Pipeline), just to start.
If the Padres don't unload Cease and Suarez, this grade bumps up to a B on the strength of 2025 championship probability added. It doesn't become an A, though, because De Vries is that strong of a prospect.
Update: As suggested, the fact that the Padres did not deal either Cease or Suarez -- as the rumors and tea leaves suggested they might -- changes the way this trade should be considered. Basically, the Padres have gone all-in and have done so with gusto. I still think dealing De Vries to add to a position of strength holds down the grade a bit, but it looks a lot better now than it did this morning. Payroll be damned -- AJ Preller is going for it. (And we've raised the grade from a D- to a B.)
Athletics grade: A
I love Miller, but come on. I never wanted the Athletics to pigeonhole Miller as a short reliever, but they did, and it feels like he's fixed there. (Though conversions, such as the Mets with
Clay Holmes, have shown it's never too late). Still, to land De Vries, just 18 and already at High-A, for a reliever is a coup.
Exciting power potential, plus plate discipline, a strong arm -- he's the stuff that stars are made of. Shortly after news of this deal dropped, I received a text predicting that someday both the AL MVP (De Vries) and NL MVP (James Wood) will be prospects Preller traded. It could happen. The fans in Vegas are going to love him.
Meanwhile, the A's add three pitching prospects. Baez and Nunez both rank in the 10 to 20 range in San Diego's system, according to analysts, but Nett was their No. 3 prospect according to MLB Pipeline, behind De Vries and talented young catcher Ethan Salas, who at last check of my text messages remains a prospect in the San Diego system, but stay tuned.
Nett has a high-end fastball (up to 99 mph, per MLB Pipeline) to headline a five-pitch arsenal. He has struck out more than 10 batters per nine innings in the minors, albeit with ugly walk rates that underscore so-so grades for command. But those walk rates have improved each season, and he's not far off from his big league debut. It's an impressive haul for the A's.
