2026 San Diego Padres Top Prospects Ranking

Salas, who played with players twice his age in the Venezuelan winter league just months before signing, made his debut in the Padres organization two days before his 17th birthday, playing for the Low-A Lake Elsinore Storm.

Coming from a baseball family—dad Jose Salas Sr. played catcher in the Atlanta system, his paternal grandfather and his dad's brother played in the minors and Ethan has two brothers currently in the minors (Jose Jr. with the Minnesota Twins and Andrew with the Miami Marlins)—Salas had a wealth of knowledge that helped elevate his prospect status. Plus, being a 6-foot-2, 185-pounder who would have had to wait another year or two before being drafted doesn't hurt, either.

He was a rare catcher that not only had elite defense, but had a good approach at the plate as a left-handed hitter. He has a proclivity for hitting the ball to all fields and was scouted with plus power. Salas showed those skills at Lake Elsinore. In his first 48 professional games, Salas had a slash line of .267/.350/.487 with nine homers, 35 RBIs and five stolen bases. Defensively, he had just one error and threw out eight of 37 steal attempts.

As the Padres are wont to do, Salas was quickly promoted to the High-A Fort Wayne TinCaps. He wasn't there very long, playing in just nine games with Fort Wayne and struggling offensively with a .200/.243/.229 slash line. With the season coming to an end, the Padres surprisingly moved Salas up again, this time to the Double-A San Antonio Missions, where he spent another nine games. There, he had a slash line of .179/.303/.214.

Baseball America and MLB Pipeline each had Salas ranked as the No. 8 prospect in baseball as he returned to Fort Wayne to start the 2024 season as a 17-year-old, the youngest player in the Midwest League. This time, he stuck around for 113 games, but the offense he showed at Lake Elisnore wasn't there. Salas put together a .206/.288/.311 slash line with four homers, 53 RBIs and 10 steals, playing against players who on average were 4.3 years older than he was. He threw out 28 of 111 runners attempting to steal in 67 games at catcher. With a full season under his belt, the Friars sent him to the Arizona Fall League, a prospect showcase. The offense was still a work in progress as he finished with a .228/.327/.424 slash line, but he did pop four homers and drove in 21.

The lack of offense started to dampen Salas' prospect luster, as Baseball America dropped him to No. 31 and MLB Pipeline to No. 33 entering 2025. Now 18 years old, Salas went up to Double-A, where he was five years younger than the average player in the Texas League. But just 10 games into the season, Salas' campaign came to an abrupt end with a stress reaction in his lower back.

Salas, now 19, is likely returning to San Antonio to begin 2026. He participated in major-league camp this year, but went just 2-for-11 (.182). He slid further in the prospect rankings, tumbling to No. 90 in the Baseball America list and not being included in MLB Pipeline's Top 100. Some outlets even moved Salas to No. 2 in the Padres' system, behind last year's first-round draft pick, left-handed starter Kruz Schoolcraft.

All of this adds up to making 2026 a key year for Salas. The defense is still there, with improvements made to his throwing process to better cut down runners. His approach at the plate has been considered simple (in a good way, with fewer moving parts) and he had an 86% in-zone contact rate in 2024 and his brief stint in 2025 before being hurt. He improved his strikeout rate by about five percentage points from 2023 to 2024 even though he didn't fare well against breaking balls.

How the Friars treat Salas if he has success offensively will be something to watch. Double-A pitching is sometimes better than Triple-A pitching due to the number of prospects at the second-highest minor-league level, so any development on that front would be a huge boon for the best catcher in the system.

While he was out injured last year and continuing this offseason, Salas worked with a number of people who have catching experience in the Padres' organization, including A.J. Ellis, Scott Servais and Mike Borzello, a current advance scout with a lot of experience on championship-winning teams as a bullpen catcher and catching coach.

It helped Salas with game-planning and other items to sharpen him defensively. He is now up to 215 pounds (and down to 6-foot-1 in revised measurements) and worked to shorten his swing to improve his offense.

"Cerebrally he’s advanced for his age, and for as little as he’s played, he absorbs the information really well," Borzello told the San Diego Union-Tribune. "Now it’s just about playing and getting reps."

Added Salas: "I think that’s why I didn’t see last year as the biggest negative in the world. I just took a lot of time to reflect, kind of make a plan starting forward and how I want to start going about things and I want to start playing and taking care of my business."

With better health, Salas could make a loud return to top prospect lists around the league in 2026. Hard as it is to believe, he's still just a teenager, as he won't turn 20 until June.

The San Diego Padres organization has been extra cautious with Kash Mayfield ever since taking the left-hander 25th overall in the 2024 MLB Draft. They delayed his pro debut until last April, and then the team capped his workload for Low-A Lake Elsinore tightly. Mayfield never worked more than five innings or threw more than 80 pitches in a game. His innings limit shrank further in midseason after he missed three weeks in May and June with inflammation in his pitching shoulder.

When he did take the mound, he showed a lot of promise. Over 19 games (all starts) and 60 2/3 innings, Mayfield produced a 2.97 ERA/3.06 FIP, a 34.1 percent strikeout rate, a 3.14 strikeout-to-walk ratio, and a 43.6 percent ground-ball rate. He was excellent at keeping the ball in the yard, allowing just two home runs in a hitter-friendly environment. His 10.9 percent walk rate was a blemish, if only slightly, given his youth and lack of consistent reps.

He succeeded despite working with a diminished arsenal. The San Diego Union-Tribune reported last September that Mayfield's fastball velocity was down about 3 mph from his days at Elk City (Okla.) High School; he topped out at 94 mph in the Cal League, compared to 97 mph in the prep ranks. The 21-year-old's offseason plans included adding weight and strength. That could bump the velocity back up.

Other aspects of pitching helped him compensate. The heater had lively arm-side run, and Mayfield created deception with both the extension from his 6-4 frame and a relatively low release point. A mid-80s changeup and upper-70s slider gave him excellent separation. In fact, the changeup is thought to be Mayfield's best pitch. It has big-time sink and fade, making it a weapon against right-handed batters, and his arm speed creates great deception. His mechanics are considered advanced; his motion looks smooth and repeatable.

Mayfield was one of 21 pitchers in the preliminary player pool for the Padres' Spring Breakout game on March 21 against the Chicago Cubs' top prospects. A strong outing against high-level competition would give him a nice boost ahead of his second minor-league season, which should begin at High-A Fort Wayne.

Kruz Schoolcraft's professional career has barely begun -- he made one minor-league appearance made at the end of the 2025 season. He'll turn 19 in April and his development will take time. The good news? There's evidence to suggest that it won't be a lot of time.

The Padres selected the 6-8, 229-pound Schoolcraft in the first round (25th overall) of last year's MLB Draft out of Sunset High School in Beaverton, Ore. He was the No. 1-ranked prep left-hander in the draft. He also was a legitimate first-base prospect with big-time power. San Diego lured him away from the University of Tennessee -- he committed to the Vols in December 2024 -- with a $3.6 million signing bonus. Then, they convinced the potential two-way star to become a full-time pitcher.

The organization waited until Sept. 6 to get him into a game. His appearance with Lake Elsinore in the Low-A California League was brief and eventful: 1 2/3 innings, one hit, two runs (both earned), three walks, four strikeouts, four stolen bases allowed. Schoolcraft showed that he has a lot of work to do.

But he still could rise quickly, for several reasons.

First, he already throws three pitches -- a mid- to high-90s fastball with good extension, a changeup with deception, and a slider with depth. Prior to the draft, MLB.com gave both the fastball and slider a 60 on the 20-to-80 scouting scale and the change a 55, but the slider is considered his third pitch at the moment. 

Second, he is considered to have advanced mechanics, which will help make his delivery repeatable sooner. It also will help him improve his 50-grade control. Of course, his longer levers make it easy for baserunners to pick up on his cadence, so he'll have to fine-tune that in order to prevent everyone faster than Giancarlo Stanton from swiping a base against him. But his mechanics as a whole are quite impressive for a teenager.

Third, the organization considers him a smart player and a hard worker. Schoolcraft showed those traits when he spoke with reporters, including MLB.com's Sam Dykstra, at spring training. He said that he wants to reshape his slider better and make it a pitch he can throw effectively both early and late in the count. He talked about getting stronger, and he shared a specific goal for 2026: he hopes to make 22+ starts.

Schoolcraft has already made an impression in camp with his sharp outing in an intra-squad game. He might make another before spring training is through. The Padres listed him in the initial 40-man player pool for their Spring Breakout game on Saturday, March 21, against the Cubs' top prospects in Arizona. There's bound to be buzz about the kid moving rapidly through the system if he gets into that game and overpowers hitters. But those people will need to be patient; Schoolcraft is just getting started.

After a successful big-league callup last September and a strong spring training this year, Rodriguez appears ready to handle a full-time role in the Padres' loaded bullpen. That's a big accomplishment for a 22-year-old who has spent half his pro career injured.

Bradgley Rodriguez joined the Padres organization in January 2021 out of Venezuela, signing for $370,000. Later that year, the right-hander showed off his live arm in the Dominican Summer League. But then came the struggles. An elbow injury led to Tommy John surgery in 2022, and the subsequent rehab cost him the 2022 and 2023 seasons. When he finally got back on the mound in 2024, he made up for the lost time. He pitched at three levels that year, capped by a promotion to Double-A San Antonio in August. He went back to San Antonio to begin the 2025 season, and then he caught the Padres' eye. In late May, he was promoted to the majors straight from Double-A. He debuted on May 31 vs. the Pittsburgh Pirates, working 1 2/3 scoreless innings, but was optioned to Triple-A El Paso three days later.

Then, the injury bug bit him again. He missed about two weeks in mid-June with biceps tightness and spent seven weeks on the IL from early July to late August. Once healthy, he earned another callup to San Diego, where the Padres were dealing with their own pitching injuries. His electric stuff and moxie earned him a spot on the club's roster for the Wild Card Series against the Cubs. Rodriguez did not appear in the series, but just being on a postseason roster was a clear sign that the club thought it might have something with him. 

Rodriguez faced just 31 batters over 7 2/3 innings in the majors in 2025, but we can still glean much from how he attacked them. He threw a four-seamer, sinker, changeup, and cutter. All three of his fastballs played up in the charged atmosphere of the Show --- the sinker and four-seamer velocity increased by a full mile per hour to 98.3 and 98.8, respectively, while the cutter velo increased by 0.9 mph to 89.2. The sinker and change showed sizable horizontal movement, with 15.3 and 16.0 inches of arm-side run, respectively. Some of that movement can be attributed to a drop in arm angle from 56 percent to 46.8 percent. According to Mad Friars, the organization made the switch to three-quarters after the biceps scare to ease the strain on his arm.

Rodriguez's pitch mix underwent a transformation last year as well. It changed from sinker-heavy in Triple-A to four-seam-heavy in the majors. The four-seamer use was just 10.6 percent at El Paso, but 40.2 percent with the Padres. The sinker use fell from 45.8 percent to 26.0 percent in the bigs. Changeup use was pared from 31.3 percent to 23.6 percent. The changeup played very well off the four-seamer, generating a 46.7 whiff rate as Rodriguez's putaway pitch. In fact, both pitches were unhittable, a .000 batting average for both. The sinker helped to produce a 56.3 percent ground-ball rate, to pair with a 29.0 strikeout rate. 

Platoon advantage played a large role in pitch selection. Thirty-one of his 33 sinkers and all 13 of his cutters were thrown to right-handed batters, while 23 of his 30 changeups were thrown to left-handed batters. The four-seamer use was more balanced --- 32 to left-handers, 19 to right-handers.

Rodriguez put himself in position to win a job out of spring training with six consecutive scoreless outings to begin exhibition play. He allowed two hits, struck out seven, and, more importantly, walked one over six innings. His chances will improve greatly if Jason Adam (quad) needs to open the season on the injured list and the bullpen has a second opening. If Adam proves ready to go, then it will be Rodriguez, Ty Adcock, Logan Gillaspie, Alek Jacob, and Ron Marinaccio vying for one spot. Gillaspie has earned praise from manager Craig Stammen for his willingness to fill any role, while Marinaccio is out of minor-league options. Rodriguez, on the other hand, can be optioned. If he does have to go back to El Paso, he'll be an early call-up option when the staff begins to go through the inevitable churn.
