Jacob Misiorowski, Junior Caminero and Every MLB Team's Best Player Under 25

All 30 MLB teams have at least one promising building block for the future, and with a wealth of young, rising talent across baseball, the future of the sport is in good hands. Jacob Misiorowski (Brewers), Junior Caminero (Rays), Chase DeLauter (Guardians) and Edgardo Henriquez (Dodgers) are all still in action and hoping to help their teams reach the World Series. With that in mind, we set out to identify the best under-25 player on every MLB roster during the 2026 season. Ages reflect how old a player was on June 30, which is the standard for how season ages are presented on Baseball Reference, FanGraphs and other sites. The focus was solely on this year's production, so long-term potential was not part of the equation, and only major league contributions were considered. Stats:132 G, 112 OPS+,.228/.297/.461, 45 XBH (24 HR), 1.1 WAR Terrific batted-ball metrics make it easy to believe in Mayo's ability to make an above-average offensive impact, even with a middling on-base percentage and strikeout rate above 30 percent. He is stretched defensively at third base (568.2 INN, -9 DRS) and blocked by Pete Alonso at first base, so primary designated hitter could be his role in 2027. Stats:26 GS, 9-6, 3.03 ERA, 1.10 WHIP, 171 K, 148.2 IP, 2.9 WAR
