Top 80 Third Base (3B) Fantasy Baseball Rankings: Roto Leagues - March Updates

Junior Caminero - Fantasy Baseball Rankings, Draft Sleepers, MLB DFS Picks

Updated fantasy baseball third base (3B) rankings for 2025 roto league drafts, as of March. Read our top 80 tiered 3B rankings for fantasy baseball drafts.

We are in the heart of the fantasy baseball draft season, with Opening Day ready to kick off shortly. All throughout the draft season, we have been helping fantasy managers with our fantasy baseball rankings. And today we are back with our MLB team's freshly-updated 2025 fantasy baseball third base rankings and tiers for roto leagues (5x5 category mixed leagues).

Cleveland Guardians third baseman Jose Ramirez has shown no signs of slowing down and is RotoBaller's top-ranked third baseman in 2025 after slashing .279/.335/.537 with 39 home runs, 118 RBI, 114 runs, and 41 stolen bases over 681 plate appearances. Tampa Bay Rays third baseman Junior Caminero continues to see his ADP rise and has blasted three home runs with eight RBI over nine spring training games. Where do they rank, and how about the rest of the 3B options? We review it all below.

The third base rankings below are specifically designed for traditional roto leagues (5x5 categories), put together by MLB team lead Nick Mariano. We also have many other rankings for various league formats, and 17 different rankings types to choose from. Some of the most popular ones are highlighted below.
