Each fall heading into the new year, Baseball America publishes one organization report for each of the 30 clubs.
These reports from our major league correspondents contain a trove of player development updates and spotlight traditional reporting. Here are 10 updates I found to be especially enlightening from our October and November reports.
Top Fall Prospect Takeaways
1. The Cubs drafted North Carolina center fielder Kane Kepley in the second round, then watched him turn in one of the loudest pro debuts of any 2025 pick. In 28 games for Low-A Myrtle Beach, he hit .299 with two home runs, 16 stolen bases and 25 walks. “We really believe in this guy, because he was probably the best contact and swing decision combination in the country last year. He’s at least a plus center fielder, and he’s going to steal a million bases,” one Cubs official said. “I mean, we saw that right out of the draft. I think nobody’s a finished product either.”
2. Brewers righthander Tyson Hardin pitched collegiately for four seasons, including two at Mississippi State, primarily out of the bullpen, but he may be just scratching the surface of his ability. He was just as much an infielder as pitcher in high school and appears to have the raw materials to succeed as a professional pitcher, including a wide repertoire and an ability to work efficiently. “There’s some natural athleticism and some really nice tools there,” Brewers senior coordinator of minor league pitching Nick Childs said. “He’s smart and hard-working and did a good job of just taking it—as cliché as it is—just one game at a time . . . He didn’t go through very many highs and lows, like we see for some of the guys—especially the first-year guys. The consistency stood out to me.”
3. “Just to see the well-roundedness of the domination in many categories,” Giants farm director Kyle Haines said of 20-year-old lefthander Jacob Bresnahan, “whether it be via swing-and-miss, whether it be getting weak contact, keeping the ball in the ballpark in a league in which homers come in bunches at times—it’s all really impressive.” Bresnahan surrendered just two home runs in 93 innings for Low-A San Jose, while striking out 124 batters and allowing 67 hits to win California League pitcher of the year honors.
4. The Orioles drafted Oregon high school outfielder Slater de Brun with the 37th overall pick, which they acquired in a trade with the Rays. Baltimore signed de Brun for $4 million, the highest bonus given to a player drafted after the first round in 2025. He “can really run, play center field (and) make a ton of contact as well—a lot of line drives . . .” Orioles vice president of player development and scouting Matt Blood said after the draft. “He’s another one of these contact guys who also walks. We feel like all those things combined give him a pretty good chance to have some success.”
5. The Blue Jays made their first foray into the Korean amateur market by signing 18-year-old righthander Seojun Moon in September. Toronto had international bonus pool money remaining from January after their pursuit of Roki Sasaki fell short. Moon is a 6-foot-4 pitcher who has gotten up to 95 mph and has a wide repertoire. He chose to sign with an MLB organization rather than enter the Korea Baseball Organization draft because “as a young child, I’ve always dreamt of pitching at the big league level,” Moon said, “so I decided to make this choice now instead of later. This is where the best players play.”
6. Venezuelan shortstop Cristofer Torin heard all the concerns about his physique and how that could impact his future at the position. The 20-year-old Diamondbacks prospect used that criticism as motivation to revamp his conditioning regimen and diet. The end result: Torin had a better season at High-A Hillsboro than he had at Low-A the year before. “He came in physically stronger,” Hillsboro manager Mark Reed said. “You could just tell that maybe mindset-wise he went into last offseason saying, ‘I’ve got to go work. That’s not the numbers I want. That’s not the guy I am. I’ve got to come back and show I’ve got a totally different mindset and physicality.’”
7. Double-A Montgomery center fielder Homer Bush Jr. led the Southern League with 142 hits, eight triples and 57 stolen bases. The 24-year-old Rays prospect has elite speed and is a gifted defender, but what he hasn’t shown consistently is power. Bush hit zero home runs in 121 games in 2025 after hitting six the year before. “You look at his body, and he wouldn’t look out of place playing (for the NFL’s Tampa Bay Buccaneers),” Rays assistant GM Kevin Ibach said. “So while the impact hasn’t quite shown up in the offensive stat line, there’s optimism about some untapped power potential.’’ The Rays acquired Bush when they dealt Jason Adam to the Padres at the 2024 trade deadline.
8. Just as he was beginning to pop on the national prospect scene, power-armed Red Sox righthander Luis Perales had Tommy John surgery in June 2024 that cost him 15 months. He “added considerable strength while rehabbing,” writes Red Sox correspondent Alex Speier, “and if he can throw enough strikes, his four-pitch arsenal gives him a chance to emerge as a midrotation starter or possibly a key reliever, if the 6-foot-1 Perales does not address his control.” Perales’ four-seam fastball averaged nearly 99 mph with outstanding riding life in three brief minor league appearances to close the 2025. After the season, the 22-year-old pitched in the Arizona Fall League but struggled with control, walking 11 in 11.1 innings, as he struck out nearly 32% of batters.
9. The Mets praise 20-year-old Randy Guzman for his work ethic, which helped him dial in on his strength as a hitter: easy raw power that is the product of incredible bat speed. The Mets say that the 6-foot-4 Guzman’s average bat speed reading is in the mid 70s, which is where sluggers live. The Dominican first baseman/corner outfielder slugged .604 in a 26-game sample in the Low-A Florida State League to close the season. If he keeps finding power like that, Guzman’s name will surface in the global prospect discussion.
10. Yankees 24-year-old center fielder Spencer Jones is one of the more prominent boom-or-bust prospects in baseball. He ranked second in the minor leagues with 35 home runs—and also second with 179 strikeouts. Double-A Somerset hitting coach Mike Fransoso helped Jones realize his power more frequently, not by overhauling his swing, but by altering his setup by using a much more open stance that allows his hips to be in a better position to start. “Sure, there were some tweaks within the swing and maybe flattening a little and not as uphill,” Fransoso said, “but the setup was the main part. Finding one he was comfortable with and then once he loads, making sure it’s free so he can go.”
