Fantasy baseball isn't what it used to be. Remember when you could just wait for the MLB Pipeline top 100 to drop, draft the first three names, and call it a day? Those days are dead. Nowadays, if you're waiting for a "top 100" list to tell you who's good, you've already lost. The real value—the stuff that actually wins leagues—is found in the data before the hype train leaves the station.
Honestly, looking at the top mlb fantasy prospects for 2026 is less about scouting "names" and more about hunting specific traits. We're looking for guys who pull the ball in the air and don't swing at garbage. It sounds simple. It’s not.
The Helium Tier: Konnor Griffin and Kevin McGonigle
If you aren't paying attention to what's happening in Pittsburgh and Detroit right now, you're missing the biggest stories of the spring. Konnor Griffin has basically become the poster child for "tools meeting reality." Last year, people were worried about his hit tool. They thought he'd strike out too much.
Then he went out and posted a 91.2 MPH average exit velocity and swiped 48 bags.
He’s 6-foot-4, 225 pounds, and plays shortstop like a gazelle. The Pirates are legitimately considering him for the Opening Day roster. If that happens, his ADP (Average Draft Position) is going to jump 100 spots in a week. You've gotta decide now if you're in or out.
Then there’s Kevin McGonigle in Detroit. He’s the opposite of Griffin in terms of "vibes" but just as lethal for fantasy. He’s a "hit tool first" guy, which usually makes fantasy managers yawn. But look at the numbers. He barely ever chases pitches out of the zone. He’s got that Mookie Betts-style path to greatness where the elite contact ability eventually allows the power to play up. Detroit has been weirdly open about him being "ready." In a 5x5 roto league, a guy who hits .290 with 15 homers and 15 steals from the middle infield is gold.
Why 2026 is the Year of the Power-Catcher
For years, catcher was a wasteland. Not anymore. Samuel Basallo is the name everyone is circling. He’s 21, he’s in the Baltimore system, and he hits the ball harder than most grown men. We're talking a 94.2 MPH average exit velocity in Triple-A.
He had a rough cup of coffee in late 2025, but ignore that. Seriously. He’s following the Junior Caminero track—struggle early, then absolute nuclear explosion. Whether he stays behind the plate or moves to first base doesn't even matter for fantasy. The bat is a 30-homer monster in the making.
The Guys Most People Are Sleeping On
- Jesus Made (Brewers): Only 18 years old but already showing elite plate discipline. He’s a switch-hitter with speed. Most people won't draft him because he's "too young," but in dynasty, he’s a top-5 asset.
- Sebastian Walcott (Rangers): If you built a baseball player in a lab, he’d look like Walcott. 6-foot-4, 116 MPH max exit velocity. He reached Double-A before he could legally buy a beer. The swing-and-miss is there, but the ceiling is the moon.
- Carson Benge (Mets): A college bat who could easily slide into the Mets' outfield by May. He’s got that boring-but-productive power-speed combo that wins championships.
The Pitching Problem: Who Do You Actually Trust?
Pitching prospects are heartbreakers. We know this. But if you’re looking for the top mlb fantasy prospects on the mound, you have to look at Bubba Chandler. He’s a former two-way player who finally focused on pitching, and the results are terrifying for hitters.
He had one blow-up outing in 2025 where he gave up nine runs. If you take that one game out, his ERA was under 2.00. He’s got elite command now, which was the final piece of the puzzle.
Then there’s Andrew Painter. People have "prospect fatigue" with him because he’s been injured for what feels like a decade. But he’s still only 22. The velocity is back. The Phillies need him. If your league-mates are "out" because they’re tired of waiting, that is exactly when you buy.
Actionable Strategy for Your Draft
Stop drafting for "need" in the mid-rounds. If a high-upside prospect like Walker Jenkins or Max Clark is sitting there, you take them.

Check the spring training lineups every single day. If Kevin McGonigle is starting at third base or second base consistently in March, the Tigers are telling you he’s on the team. Don't wait for the official announcement.
Focus on "Hard Hit %" and "Zone Contact %" in the minor league data. These are the two most stable metrics that project success at the MLB level. Guys like JJ Wetherholt (Cardinals) pop in these metrics, making them much safer bets than the "flashy" guys who rely on 70-grade speed but can't hit a high fastball.
Audit your dynasty roster for "stagnant" prospects. If a guy has spent three years in Double-A and hasn't improved his walk rate, trade him for a 2026 flyer like Kade Anderson or Trey Yesavage. Momentum is everything in fantasy scouting.
