Yo Delta Dynasty! Welcome back to MLB Daily Delta. I'm Aaron Jolly, and today we are continuing the Spring Training Sleeper Spotlight with the most electric name in all of baseball right now — a 19-year-old shortstop who just got reassigned to the minors after spring training, and whose fantasy A.D.P. is still moving like a rocket ship in the other direction. Today's player is Konnor Griffin of the Pittsburgh Pirates — the number one prospect in all of baseball, a player FanGraphs just called one of the top handful of prospects they have ever evaluated in their entire modern era, and the most important late-round stash of the entire 2026 fantasy season.
We cover:
- 2025 Minor League Player of the Year: .333/.415/.942, 21 HR, 65 SB across 3 levels as teenager
- Spring training: 3 HR in first 6 games, finished .184 overall
- FanGraphs comparison: Bobby Witt Jr., young Hanley Ramirez, faster Carlos Correa
- Baseball America grades: Hit 60, Power 70, Run 70, Field 60, Arm 70
- ADP 200-280 range despite no MLB experience
- Bull case: June/July callup, 40-50 steal upside, Pirates need him
- Bear case: August/September debut, contact development, Pittsburgh context
- Draft strategy: 15-team stash vs 10-12 team waiver wire monitor
- Format analysis: 5x5, OBP, points leagues
This is MLB Daily Delta; I'm Aaron Jolly. With Konnor Griffin, your delta is simple: do you trust the most credible prospect evaluation in the sport and stash the potential franchise player of the next decade before Opening Day — or do you let a .184 spring training average from a teenager talk you out of the most exciting upside pick available at any position, at any price?
