The Arizona Fall League rosters were announced on Wednesday afternoon and there were six players from the Cincinnati Reds organization and one guy from a coaching staff named to the Peoria Javelinas clubs. The Reds top prospect, Alfredo Duno, headlines the Peoria roster but is joined by several other of Cincinnati’s top 25 prospects. Infielders Cam Collier and Leo Balcazar join pitchers Johnathan Harmon, Luke Hayden, and Trevor Kuncl on the roster along with Duno. Louisville Bats coach Julio Morillo (simply listed as a coach with the Bats) will be the Javelinas manager this fall. Update on October 3rd: Rhett Lowder has been added to the Javelinas roster.
Alfredo Duno has one of the best seasons by a teenager in quite a while within the Cincinnati Reds farm system. He had one of the better seasons in minor league baseball this year by a teenager, too. Baseball America noted today that he’s the only teenager with 30+ doubles and 15 home runs in a season over the last three years. The Venezuelan-born catcher played in 113 games for Daytona this season and hit .287/.430/.518 and led the league in nearly every offensive category except batting average – in which he finished second – and stolen bases. The Reds #1 prospect now that Chase Burns has graduated his eligibility, Duno will begin the postseason tonight with the Tortugas as they vie for a Florida State League championship.
Cam Collier’s season started and will now end out in Arizona. The team’s #7 prospect and the Reds are hoping things go better for him later in the year than they did early on. Collier, who was in big league camp as a non-roster invitee this spring training, injured his thumb while playing first base and wound up needing surgery. He missed the first six weeks of the minor league season before beginning to play in rehab games with the ACL Reds. Then he spent 11 games with Dayton before moving up to Chattanooga on June 17th. That’s where he has played ever since.
The 20-year-old first baseman (who has occasionally played third) has battled some consistency with the Lookouts and went through a 3-week slump where he went 4-52 from late July through August 17th. Since then, though, he’s turned things around quite a bit. In 20 games since then he’s hitting .351/.448/.446 with 13 walks and 16 strikeouts as he looks to close out the regular season on a high note before beginning the playoffs with Chattanooga next week.
Leo Balcazar – Cincinnati’s #15 rated prospect – spent the first half of the season playing shortstop for the Dayton Dragons. In his 75 games for Dayton he hit .262/.333/.413 with 27 extra-base hits, 29 walks, and 51 strikeouts. Right before the MLB All-Star break he was promoted to Double-A Chattanooga. With Edwin Arroyo on the team, Balcazar has spent much of his time with the Lookouts playing second base.
The 21-year-old infielder from Venezuela has seen his power dry up in Double-A. He’s only had six extra-base hits in 47 games played. What he has done, though, is walk more often and strike out less often. In fact, he’s walked more often than he’s struck out in his time with Chattanooga while hitting .253/.340/.324.
Johnathan Harmon, like Cam Collier, missed time this season due to injury. The right-handed pitcher missed a lot more time than his teammate in both 2024 and 2025 did, though, as Harmon was recovering from Tommy John surgery and didn’t take the mound in games this season until July 8th when he made his first of three rehab appearances out in Arizona before joining the Dayton Dragons on August 6th.
For Harmon, similar to how things are for Collier, the goal is to simply get more time on the field to try and make up a little bit for lost time. Harmon has thrown just 28.2 innings this season. His regular season is over unless the Reds promote him. But even if they don’t, he could probably add another 20-25 innings in his time out in Arizona.
Luke Hayden spent his entire 2025 season with Dayton. The 22-year-old righty made 24 starts for the Dragons and threw 101.1 innings while posting a 4.09 ERA. Hayden gave up 82 hits and struck out 79 batters. But he also had 72 walks and hit seven guys – meaning he actually handed out more free passes to first than he had strikeouts on the season.
While his strikeout-to-walk ratio wasn’t great in the early part of the season, he had 15 walks and 34 strikeouts in his first seven starts. But from May 28th through the end of the year he had 57 walks and just 45 strikeouts as he struggled to find any sort of consistency with the strikezone.
Cincinnati is sending just one reliever to the fall league this year and it’s both a surprising and unsurprising choice. Trevor Kuncl had never pitched in an affiliated baseball game before this season (he did sign with the Rangers in February of 2024 but was released late in spring training). After four years at George Washington University he went undrafted and played three years of baseball in the Frontier League. Last offseason he pitched in the Mexican Winter League before signing with the Reds shortly after the league began play in October.
The 26-year-old was assigned to Chattanooga out of spring training and he has spent the entire season working as the Lookouts closer. The righty is 3-0 with 20 saves and a 2.25 ERA this year. In his 48.0 innings he’s given up 36 hits, just two home runs, walked 17, and he’s struck out 49 batters. He’s a bit older than your typical send, but he showed some quality stuff this season, had outstanding numbers (the season hasn’t quite ended yet), and perhaps the Reds want to get a longer look at him against some more higher-end competition.
Julio Morillo will be the manager of Peoria and has had some experience with some of these players in the past. In 2023 and 2024 he managed the Daytona Tortugas and had Alfredo Duno, Leo Balcazar, Cam Collier, Johnathan Harmon, and Luke Hayden all play for him. Only Trevor Kuncl has not been managed in the past by Morillo.
The Arizona Fall League will get underway in four weeks. The first game will be played on October 6th and the league’s regular season will come to an end on November 12th and the single elimination game playoffs will finish on November 15th. The Fall Stars game will take place near the end of the season, as it always does, and be played on November 9th.
As of today there is not yet a schedule for which games will be streamed online for fans to watch. But over the last few years most games were available to watch. When we get closer to the season I will be sure to update everyone on that and have links available for where to go and how to watch games.
