23-Year-Old ShortstopSS
Washington Nationals AA
2026 Fantasy Outlook
King is an athletic speedster who plays multiple positions and is aggressive at the plate. He made up somewhat for an underwhelming 2025 regular season (88 wRC+) with a strong showing in the Arizona Fall League (1.031 OPS in 18 games). Including the AFL, King stole 36 bases on 40 attempts in 143 games. That speed will be his primary appeal in fantasy, as King has fringe-average power, and even in a best-case scenario, he probably won't log high on-base percentages -- he'll always be more valuable in batting average leagues. What's working in King's favor is his pedigree (No. 10 overall pick in 2024) and defensive chops. He can play anywhere on the field, including shortstop, so there could be years where King is eligible at multiple positions in fantasy. He will presumably head back to Double-A after slashing .233/.287/.313 with three homers and a 0.31 BB/K in 80 games there in 2025. Read Past Outlooks

Breaking out in Double-A repeat
SSWashington Nationals  AA
May 1, 2026
King is slashing .295/.409/.602 through 23 games for Double-A Harrisburg with six homers, three steals, 23 runs and 24 RBI.
Analysis
The 2024 first-round pick may have been the biggest beneficiary of the Nationals' overhaul of their minor-league development program under new president of baseball operations Paul Toboni. King's 1.011 OPS is more than 400 points better than what he managed in 80 games at Harrisburg last season, and advanced metrics paint an even rosier picture of the 23-year-old's improvement. Per Spencer Nusbaum of The Athletic, King's average exit velocity has jumped from about 87 mph to 93.5 mph, and his chase rate has dropped from about 38 percent to around 25 percent. The Wake Forest product is knocking loudly on the door for a promotion to Triple-A Rochester.
