Seaver King

23-Year-Old ShortstopSS
Washington Nationals AAA
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

Gets bumped up to Triple-A
SSWashington Nationals  AAA
May 18, 2026
The Nationals promoted King from Double-A Harrisburg to Triple-A Rochester on Monday, Spencer Nusbaum of The Athletic reports.
Analysis
King struggled after being promoted to Harrisburg last season, but he's broken out in 2026, slashing .336/.427/.562 with five home runs, five stolen bases and a 22:31 BB:K in 35 games to earn a promotion to the Nationals' top affiliate. The 23-year-old has played shortstop almost exclusively in pro ball, but King has seen a bit of action at second base in 2026, and if he makes it to the majors this season, it could be as a second baseman.
