Oakland Athletics Top 28 Prospects

Below is an analysis of the prospects in the farm system of the Oakland Athletics. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the third year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but I use that as a rule of thumb.

Other Prospects of Note
Grouped by type and listed in order of preference within each category.
Fallen Stars
Pedro Pineda, CF
Robert Puason, SS
Lazaro Armenteros, OF
Each of these three was a top 10 prospect in the A’s system at one point but has since hit significant stumbling blocks. Pineda, who missed time in 2022 due to injury, has good bat speed but struggles to recognize strikes, resulting in an inflated K rate while still at Low-A. He is now seen as a player with high injury risk and frightening swing-and-miss issues. Puason has stopped switch hitting. He continues to bounce back and forth between Low-A and the complex with little sign of lasting improvement regarding his lack of contact. Lazarito’s strikeout rate is lower than last season, but that’s only because last year it was in the mid-40s. Oakland can ill-afford for their high-bonus international misses to be this big.
The Walkers
Brennan Milone, 1B/2B
Caeden Trenkle, OF
Angel Arevalo, 2B/CF
Milone is a tad old for Low-A, but is nevertheless walking about as much as he’s striking out there, though he’s hard to place defensively. On the flip side, Trenkle is an easy fit in center field, and his patience at the plate resulted in him reaching base safely in his first 18 games at High-A. He was placed on the IL in early May and is now ramping back up on the complex. Also freshly returned from injury is Arevalo. His walk rate is comically high (as is his strikeout rate), but his sample is comically small, as his season only began in earlier this month.
The Runners
Junior Perez, RF
Euribiel Angeles, 3B
Max Schuemann, SS/OF
Perez’s 19 stolen bases rank second in the A’s system, while his OBP ranks as one of the lowest in the org due to him striking out in roughly a third of his plate appearances. Angeles is a threat on the basepaths as well, but his roughly 1% walk rate isn’t doing him any favors. Schuemann is a jack of all defensive trades. He returned to Triple-A earlier this year and proceeded to bring his strikeout rate down by more than eight percentage points relative to his Double-A mark while slugging more than ever and ranking second in stolen bases at Las Vegas.
Command Struggles
Jorge Juan, SP
Blake Beers, SP
Yehizon Sanchez, SP
Jacob Watters, SIRP
Juan started the year with 14.1 dominant innings at High-A, where he struck out nearly half his opponents to help make up for a walk rate above 16%. Since reaching Double-A, his walk rate has held steady while his strikeout rate has plummeted below 20%. Beers has put up similar numbers to Joey Estes this year, and his slider is still a plus offering, but he’s a few years older than Estes with a less data-friendly four-seamer. Sanchez posted a 2.51 WHIP at Low-A to start the season; opposing hitters averaged .378 against him, so he’s been sent down to the complex again. Watters is still starting this season, and his 15% walk rate so far at High-A is actually significantly lower than in his first taste of professional pitching last year, but the command and arsenal still seem more appropriate for a reliever.
Ailing Arms
Stevie Emanuels, SP
Eduardo Rivera, SIRP
Jack Weisenburger, SIRP
Emanuels and Rivera have both returned from injury this season to varying results. Emanuels began the year with three appearances on the complex and is now back at High-A, where he’ll look to recapture the movement and spin on his arsenal that has historically allowed it to play up. Rivera missed much of 2022 to injury, then started this season on the IL as well. When he returned, he skipped the complex, instead heading right to Low-A, where he has struggled to find the zone consistently. Weisenburger hasn’t pitched since May 2022, having thrown only nine innings that season. His injury track record is particularly concerning due to the violence in his delivery.
System Overview
Even the most casual baseball fans have heard about what’s going on with the A’s this year. But before persistent “sell the team” chants started to resound within the concrete confines of the Coliseum during every home game came the trades that inspired those disgruntled cheers, deals that sent away Oakland’s biggest names largely in exchange for prospects. As a result, only about half of the players listed above were originally signed by the A’s.
A few of the players acquired in the team’s recent blockbuster transactions are now on the big league squad, including Esteury Ruiz (Sean Murphy trade) and Shea Langeliers (Matt Olson trade), but most of them have had much less success since their arrival. In particular, nearly all of the highly-touted pitching prospects these trades netted have struggled in one way or another, whether it be a velocity decline, dwindling command, injury, or some combination of the three.
Based on how the A’s rotation and bullpen have performed at the big league level, it’s no surprise that their system is largely characterized by a downtick in pitching performance, one that isn’t limited to the trade acquisitions. Whether it’s the woes of Mason Miller (injury) and Ken Waldichuk (command) atop the list, or the downward skid of Ryan Cusick and J.T. Ginn, who now find themselves towards its bottom, it’s harder to find a hurler who is truly thriving than it is to spot the ones who are struggling.
There’s greater optimism to be mined from some of the homegrown position players, like Lawrence Butler’s improving swing and miss tendencies or the quick ascent of young Zack Gelof. But given the overall aura surrounding the Athletics at the moment, it would have perhaps been unreasonable to expect the apparent apathy exhibited by ownership towards the current team (at least, in its current location) not to impact the quality of its minor league system as a whole. When I attended an A’s game recently, I overheard groups around me hoping to see ownership start to invest more whole-heartedly in the team’s future when it relocates. But even if we see a meaningful shift in organizational philosophy — one that prioritizes retaining talented young players and winning at the big league level — Oakland has fallen behind other front offices and farm systems. The next good A’s team is likely a ways away wherever it plays.

Woof.
25% winning percentage in the majors, only 28 prospects worth a writeup, and the top two were clearly misevaluated in the offseason in terms of how ready they were. This is bleak.
Well, least I’m also a Tottenham fan.
