Dynasty rankings are never static. Every season brings breakouts, busts, injuries, and surprises that reshape how the community values players. Looking back at 2025, a handful of players saw their dynasty stock skyrocket while others experienced significant declines.

Using data from the HarryKnowsBall crowdsourced rankings, we tracked every player's value from January 1st through December 12th, 2025. Here are the ten biggest risers and ten biggest fallers of the year, ranked by total value accumulated and lost.

Biggest Risers of 2025

These players saw the largest increases in dynasty value over the course of the year, as voted by the dynasty community.

1. Nick Kurtz (178 → 7, +171 spots)

Kurtz is the single biggest mover in this list. A true dynasty centerpiece. He debuted in April and finished with 36 HR and a 1.002 OPS in 2025, putting an exclamation point on his season with a 4-homer game in July. Time will tell how high this rocket ship can go.

2. Cal Raleigh (186 → 24, +162 spots)

Raleigh hit 60 homers in 2025, setting Seattle’s single-season HR record and the catcher HR record. Enough said? A true middle-of-the-order bat at catcher who put contending dynasty teams on his back all season.

3. Konnor Griffin (251 → 32, +219 spots)

Griffin’s name was synonymous with "high upside" when he got selected as the 9th pick of the 2024 MLB draft, and boy did he deliver. Griffin finished 2025 with 21 HR, 65 SB, and a 1.019 OPS in the minors. Good luck trading for him now.

4. Pete Crow-Armstrong (118 → 23, +95 spots)

PCA turned his elite tools into legit category-winning fantasy output. In 2025 he posted a true power/speed season (31 HR, 35 SB) while playing an elite CF. A cool second half hasn’t dissuaded HKB users.

5. Jacob Misiorowski (212 → 35, +177 spots)

Triple-digit stuff, big strikeout totals, and major league production in 2025 (87 K). Even the all star game gave him his flowers (somewhat controversially). There’ll be some volatility, but his bat-missing arsenal and youth is pushing him into an elite dynasty tier.

6. Roman Anthony (61 → 19, +42 spots)

Anthony was a consensus top 1-2 prospect before the season began and he backed it up with real production. After debuting June 9, he hit .292 with an .859 OPS and a .396 OBP (best among qualified rookies), finishing third in AL ROY voting despite a season-ending oblique issue. That’s the recipe for a dynasty cornerstone.

7. Kevin McGonigle (615 → 60, +555 spots)

McGonigle went from sleeper to mainstream after a monster 2025. He hit .305/.408/.476 across A/A+ and then won Arizona Fall League MVP. Sleeper no longer — there’s room for more upward mobility here.

8. Jesus Made (694 → 64, +630 spots)

Made was perhaps the most hyped prospect coming into this season, as a 17 year old putting up absurd numbers in the Dominican Summer League, and he delivered on the hype. He stole 47 bases in 2025 and seemed to level up with each promotion.

9. Cristopher Sanchez (220 → 41, +179 spots)

Sánchez earned his jump by pitching like a frontline starter over a full workload: 13–5 with a 2.50 ERA, 202.0 innings, and 212 strikeouts in 2025. Still only 29 years old, he’s an anchor for any dynasty rotation.

10. Hunter Brown (102 → 28, +74 spots)

Brown’s step forward was legitimate ace-level output: a 2.43 ERA with 206 strikeouts in 185.1 innings, plus he reached the 200-K mark while staying efficient deep into games. That profile is how a pitcher jumps into top-30 dynasty territory.

Biggest Fallers of 2025

Not every player had a good year. These ten saw the steepest declines in dynasty value, whether due to age, injury, or disappointing performance.

1. Mookie Betts (18 → 57, -39 spots)

Betts is still great, but 2025 brought enough uncertainty to move dynasty markets. He finished with a .765 OPS and 20 HR and also dealt with a toe fracture, along with a well documented illness at the beginning of the season. He’ll be entering his age 33 season but this might be a good buy window for win-now teams. A bounce back doesn’t seem too far fetched.

2. Michael Harris II (33 → 126, -93 spots)

Harris’ fall was driven more by the bat than the tools: he was one of MLB’s least productive hitters for long stretches in 2025, and the plate-discipline/quality-contact issues were loud enough to spook dynasty managers. Even with his speed (and a late-year surge), a .653 OPS season forces a valuation reset.

3. Corbin Burnes (38 → 135, -97 spots)

This one’s mostly health. Burnes hit the IL with elbow inflammation and then underwent Tommy John surgery in early June, wiping out the rest of 2025 and putting 2026 in question. It’s fair to wonder if he’ll be the same pitcher even when he returns.

4. Ozzie Albies (46 → 170, -124 spots)

Albies’ decline got supercharged by another major hand injury: his 2025 season ended with a fractured left hamate bone. Even in a week 2B landscape, recurring health disruptions (and now another offseason of rehab) drag the long-term outlook.

5. Roki Sasaki (28 → 76, -48 spots)

The hype cooled because the rookie MLB transition was a bumpy one. Sasaki posted a 4.72 ERA through eight starts with shaky control before a right shoulder impingement sent him to the IL. He ultimately shifted to a bullpen role late.

6. Luis Robert Jr. (47 → 168, -121 spots)

Robert’s value drop is the familiar story: elite tools, but availability keeps failing him. He went on the IL with a hamstring injury midseason and later suffered a Grade 2 strain that further affected availability. He ended up with a .223 average and 14 HR in 110 games. If the market cools any more he’ll be an intriguing buy low entering 2026.

7. Kyle Tucker (6 → 20, -14 spots)

Tucker is still a star, but 2025 reminded everyone how quickly sentiment can change. A calf problem lingered, sent him to the IL in September, and required outside treatment before he returned. When the top of dynasty is crowded, even a short injury stretch can knock a player out of the very top tier.

8. Austin Riley (23 → 58, -35 spots)

Riley’s drop is injury and performance driven. A core muscle issue ended with season-ending surgery in August. It’s also his second straight year of non-elite production. The market still hasn’t given up hope, but trust is dwindling.

9. Grayson Rodriguez (48 → 167, -119 spots)

Young pitcher + elbow surgery. Not fun. He underwent an elbow debridement (not a made up word) procedure and was ruled out for the season, which forces the market to price in both missed development time and long-term durability questions.

10. Gunnar Henderson (3 → 12, -9 spots)

Henderson’s dip is more about his prior standing, than outright collapse, but 2025 wasn’t perfectly clean. He opened the year on the IL and finished with a still-strong but slightly less dominant line (.255, 29 HR, .808 OPS). When other young stars pop, even tiny wobbles can move you a few spots.

Final Thoughts

Dynasty rankings are always in motion. The players who rise and fall each year tell us a lot about how the community values age, upside, health, and production. Tracking these trends can help you get ahead of the market, whether you're buying low on a faller or selling high on a riser. Who do you think sees the biggest shift in 2026?
