Top 200 Dynasty Rankings (Coming Soon)

Ranking Notes

  • Dynasty ratings are based over the next 5 years and based on traditional 5×5 roto category scoring formats
  • Austin Riley remains one of the most dependable power bats at third base. Despite a rise in strikeout rate and a dip in contact metrics in 2025, his long-term contract and everyday role ensure volume. Expect 30+ homers annually, though his batting average may trend downward as he ages.
  • Noelvi Marte (23) has had a nice resurgence in the 2nd half of 2025. While his groundball rate is above league average, he still projects as a plus contributor across all five categories which is rare at the position.
  • Jordan Westburg has an ultra-aggressive approach in the zone leading to a low walk rate. His consistent slash line and barrel rates give him a solid floor. There could be more upside if he can learn to be more selective and hunt better pitches.
  • Addison Barger has catapulted up fantasy rankings with an impressive sophomore campaign. He consistently taps into his plus raw power and has easy 30 homer power going forward. 
  • Royce Lewis continues to be plagued by injuries. His max EV’s are down this season and his surface numbers are underwhelming. However, his xBA and xSLG suggest there’s more under the hood. His mix of low strikeout rates and strong max exit velocities remind us why he was once a top prospect. If he can stay healthy, the breakout potential remains there.
  • Matt Shaw is quietly putting together a strong rookie season with double-digit homers and steals in limited work. While he lacks standout tools, he grades out as average to above-average across the board which makes him a 5-category contributor.
  • Max Muncy is enjoying a bounce-back 2025, pacing for his best batting average since 2018. With his improved contact rates back to his mid-career form, despite being 34, he profiles as a productive slugger over the next few years
  • Miguel Vargas has taken steps forward in his first MLB season, improving both his strikeout rate and hard-hit metrics. Though he lacks plus bat speed or exit velocities, his disciplined approach and solid hit tool make him a viable everyday corner bat while having only average power.
  • Ryan McMahon gets a lineup upgrade with his move to the Yankees while remaining in a hitter friendly park. While no longer in Coors, he is still a solid bet for 20+ homers through the end of his contract (2027), especially in deeper formats.
  • Connor Norby’s 2025 wrist surgery may temprorarily reduce his power output, but his pull-heavy approach and 90th percentile sprint speed still offer double-digit homer and steal upside. His swing-and-miss tendencies and modest EVs pose risk, but he could be a sneaky value if the contact improves.
  • Kyle Karros made the leap from Double-A to his MLB debut in 2025 with his sub-20% strikeout rates and strong zone contact. The power is still developing, but with everyday reps, he could develop into a Coors Field doubles machine.
