Opening Day is roughly six weeks away, and if you're in a fantasy baseball keeper league, the clock is ticking. Most leagues set keeper deadlines somewhere between mid-February and mid-March, which means you need to make your decisions now — not the night before.
This isn't a standard rankings list. You can find consensus top-300 lists anywhere. Instead, this is a guide to thinking about keeper value — which players offer the most surplus relative to their cost, which positions have the most scarcity, and what factors should drive your keep-or-throw-back decisions heading into 2026.
What Makes a Good Fantasy Baseball Keeper?
Before we get into names, let's establish the framework. A great keeper isn't necessarily a great player — it's a great player at a great price. Four factors matter most:
1. Surplus Value
The gap between a player's expected production and their keeper cost is everything. A borderline All-Star kept in the 15th round is more valuable than an MVP kept in the 1st round. You can draft MVP-caliber players with a 1st-round pick anyway — you can't draft 15th-round All-Stars.
2. Age and Career Trajectory
Baseball aging curves matter for keepers. Hitters typically peak between ages 26-30, while pitchers are harder to predict. A 24-year-old coming off a breakout is the ideal keeper profile — you're buying into the upswing. A 33-year-old coming off a career year is the opposite — you might be buying the peak and riding the decline.
3. Position Scarcity
Not all positions are created equal. Catcher is a desert, shortstop is overflowing with talent, and starting pitching is always one oblique strain away from disaster. Keeping a top-tier catcher or a genuine ace has outsized value because the replacement level at those positions is so much lower.
4. Contract/Cost Trajectory
If your league uses escalating keeper costs, you need to think about not just this year but the next 2-3 years. A player who costs a 12th-rounder this year, a 10th next year, and an 8th the year after is still a fantastic value. A player who costs a 3rd-rounder and escalates to a 1st? You might only get one year of true surplus.
Top Keeper Values by Position
The following isn't a ranking of the best players — it's a ranking of the best keeper values. Your league's specific costs will vary, but these are the tiers of players where keeper decisions get most interesting.
Catcher
Catcher remains the thinnest position in fantasy baseball, which makes any above-average option a strong keeper candidate.
- Adley Rutschman — At 26, he's the consensus top catcher and still potentially improving. If you have him at anything below a 3rd-round cost, he's an easy keep. The positional advantage is massive.
- William Contreras — Dual eligibility (C/DH on some platforms) adds flexibility. If he's a mid-round keeper cost, he's worth holding.
- Top catching prospects — Keep an eye on whoever your league's prospect darlings are behind the plate. A catcher who can hit and is kept for free is one of the highest-value keeper plays in baseball.
First Base
First base has rebounded as a position of strength. The keeper question here is about separating the truly elite from the merely good.
- Vladimir Guerrero Jr. — Elite bat, entering his prime at 27. First-round talent, so he's only a keeper if your cost is a 2nd or later.
- Matt Olson — Power is never in question, but Ks and average fluctuations make him a better keeper value than a straight first-round pick.
- Breakout candidates — Did your league have a first baseman who popped late last year and went undrafted or cheap? Those are the gold-mine keepers at this position.
Second Base
Second base has gotten significantly more interesting with the influx of athletic, multi-category contributors.
- Marcus Semien — Age (35) is the concern, but he's been a model of consistency. Keep if cheap; let walk if he costs a top-5 round pick.
- Nico Hoerner / Young Contributors — Speed-first middle infielders who contribute across categories make excellent mid-round keeper values.
Shortstop
The deepest position in baseball. This means keeper value at SS needs to be truly elite to justify over other positions.
- Bobby Witt Jr. — 25 years old, five-category stud. Worth a first-round keeper cost because he's arguably the #1 overall player in fantasy.
- Elly De La Cruz — The speed/power combination is historic. Volatile but the upside is generational. An easy keep at any cost below the top 3 rounds.
- CJ Abrams, Anthony Volpe — Young shortstops who are still ascending. If they're mid-round keeper costs, the trajectory is your friend.
- Depth note: Because SS is so deep, a "good" shortstop kept in the 4th round might actually be worse value than a "good" catcher kept in the 10th. Think about positional replacement level, not just raw talent.
Third Base
Third base is a tale of the elite few and a long tail of replacement-level options.
- Gunnar Henderson — Only 24 and already a top-10 overall player. If he's on your roster at any keeper cost, you keep him.
- José Ramírez — 33 and still producing at an elite clip. The age flag is real in dynasty formats, but for 2-3 year keeper windows, he's still locked in.
- Jordan Walker / Young 3B — If you stashed a young third baseman before their breakout, this is where keeper leagues pay off. The position is thin enough that emerging talent has outsized value.
Outfield
Outfield is deep but the elite tier is small. The keeper value play is finding the guys who are about to jump from "good" to "great."
- Julio Rodríguez — 25, five-category ceiling, and in an elite keeper window. Keep at nearly any cost.
- Corbin Carroll — After a sophomore adjustment, the talent and speed are still there. A mid-round keeper cost makes him a strong hold.
- Jackson Chourio, Wyatt Langford — Young outfielders entering year 2-3. If your league allows you to keep them cheaply, the upside is enormous.
- Juan Soto — Elite hitter, but at 27 he's already expensive in most formats. Only a keeper if your cost is below his ADP.
Starting Pitching
Pitching keepers are the highest-risk, highest-reward category. An ace kept cheaply is league-winning; an ace who gets hurt in March is a wasted keeper slot.
- Skenes, Richardson, other young aces — Young pitchers with elite stuff and cheap keeper costs are the best SP keeper plays. The risk is real (innings limits, injuries), but the ceiling is worth it in most keeper formats.
- Established aces (Cole, deGrom-type) — Only keep if significantly below ADP cost. Injury risk makes pitching keepers inherently volatile.
- General rule: Don't use more than 1-2 keeper slots on pitchers unless the value is overwhelming. Batting keepers are safer and more predictable.
Relief Pitching
Almost never worth a keeper slot. Closer roles are volatile, and you can draft saves in the middle rounds. The only exception is a truly elite closer (think prime Kenley Jansen) kept at a last-round cost — and even then, it's debatable.
The Decision Framework
When you're staring at your roster and trying to decide who to keep, run every player through this checklist:
- What's their keeper cost vs. expected ADP? If the cost is higher than where you'd draft them, throw them back.
- How many years of keeper eligibility remain? A player with 3 years left is worth more than one with 1 year left at the same cost.
- What's the positional replacement level? Keeping a top-5 catcher is more impactful than keeping a top-5 outfielder because the drop-off is steeper.
- What's the age/trajectory? Bet on ascension over decline whenever costs are similar.
- What does your team need? Don't keep 3 shortstops. Balance your keeper selections to set up a strong draft foundation.
Use Tools to Compare, Not Just Gut Feel
One of the biggest mistakes managers make is relying on gut feel for keeper decisions. "He was great last year, I'm keeping him" ignores cost, positional value, and the opportunity cost of that keeper slot.
Tools like KeeperTracker let you see every keeper-eligible player on your roster alongside their cost, years kept, and eligibility status. When you can compare all your options side-by-side with the actual numbers, you make better decisions. It takes the emotion out of it — and in keeper leagues, emotion is the enemy of good roster construction.
The Clock Is Ticking
Spring training is underway. Keeper deadlines are approaching. The moves you make in the next few weeks will shape your team for the entire 2026 season — and potentially beyond.
Don't rush it, but don't procrastinate either. Do your research, compare your options, and make your keeper decisions with data and framework — not just last year's box scores.
