Fantasy Baseball Opening Day: Sleepers & Must-Have Team

Fantasy Baseball Opening Day is finally here… sort of.

The 2026 MLB season kicks off with a single-game teaser before the full slate arrives, and while the format leaves something to be desired, the fantasy baseball implications are already in motion. From injury updates to bold predictions and “my guys” lists, there’s plenty to unpack before fantasy baseball lineups lock across the industry.

Fantasy Baseball Opening Day: Sleepers & Must-Have Team

Let’s break down the biggest takeaways from the FantasyPros “Leading Off” episode and what they mean for your fantasy squads right now.

Opening Day Feels… Off, But Fantasy Is Full Go

There’s no way around it. A one-game Opening Day doesn’t hit the same. The energy of wall-to-wall baseball is missing, and for fantasy players, that means fewer immediate data points and a slower ramp-up.

Still, the season has technically begun, and that’s enough to shift into in-season mode. Waiver wires, lineup decisions, and streaming strategies all start now.

Injury News to Monitor Early

The biggest headline: Gerrit Cole is officially on the IL to start the year.

There’s optimism he could return in May, making him a prime stash candidate if your league has IL flexibility. The advice here is simple: grab him, sit him for a few starts upon return, then deploy once he’s fully stretched out.

Meanwhile, Carlos Rodon is also sidelined, further muddying the Yankees rotation outlook early in the season.

Welsh’s All-2026 Fantasy Team: Value and Upside Blend

Welsh’s roster leans into cost-effective upside and category juice:

Key Targets

Will Smith (C – LAD)
Falling in drafts despite top-tier production potential.

Vinnie Pasquantino (1B – KC)
A favorite breakout bat, especially with ballpark changes boosting power outlook.

Jeremy Pena (SS – HOU)
Injury discount + strong spring signals = value.

Wyatt Langford (OF – TEX)
A 20/20 baseline with room for more.

Chandler Simpson (OF – TB)
Elite speed with sneaky average. A potential league-winner in stolen bases.

Pitching Core

Logan Webb as the stable SP1
Upside arms like Chase Burns

The theme: build a stable base, then chase ceiling.

Joe’s All-2026 Fantasy Team: Youth Movement and Breakouts

Joe’s roster leans more aggressive, with a heavy emphasis on young bats and upside plays.

Core Hitters

Francisco Alvarez (C – NYM)
Still just 24, with 30-HR upside at catcher.

Bo Bichette (SS – NYM)
A bounce-back candidate with contract-year motivation.

Roman Anthony (OF – BOS)
One of the most exciting young bats entering 2026.

Jac Caglianone (OF – KC)
Massive power upside and rising hype.

Pitching Targets

Eury Perez
Devin Williams anchoring saves

Joe’s approach leans into ceiling and breakout potential, especially with prospects ready to impact early.

Chandler Simpson: The Bold Prediction That Could Win Leagues

One of the most aggressive calls from the episode: Chandler Simpson could steal 100 bases.

That sounds wild, but the logic checks out:

Elite stolen base rate per plate appearance
High contact profile
Improved MLB rules favoring base stealing

Even if he falls short, 50+ steals feels like a realistic floor. That alone makes him a premium fantasy asset.

Shohei Ohtani Is Still the Cheat Code

After an 11-strikeout performance, Shohei Ohtani continues to redefine fantasy value.

In daily lineup leagues, the flexibility to use him as both hitter and pitcher creates unmatched roster leverage. If your format allows it, he’s still the clear 1.01.

Tyler O’Neill Opening Day Streak: Bet or Stay Away?

Tyler O’Neill has homered on Opening Day six straight years.

Seven in a row would be historic. The odds sit around 3-to-1, making it one of the most talked-about bets of the slate.

The hosts? They’re out.

The takeaway? Fun narrative, but don’t force it into your betting strategy.

Connelly Early Watch

Prospect arms like Connelly Early are already creating buzz.

Even if usage is limited early due to service-time manipulation, the advice is clear:

Add now
Be ready to churn if needed
Monitor performance closely

These are the types of players that swing leagues by midseason.

Fantasy Baseball Takeaways

Stash Gerrit Cole if you have IL space. May return could provide ace-level value.
Target undervalued hitters like Vinnie Pasquantino and Jeremy Pena in drafts and trades.
Chandler Simpson is a must-roster for stolen base upside. Could lead MLB.
Lean into upside prospects like Roman Anthony and Jack Caglianone where possible.
Shohei Ohtani remains the most valuable fantasy asset in flexible formats.
Don’t chase narrative bets like Tyler O’Neill unless you’re comfortable with the risk.
Be aggressive early with pitching prospects. Quick adds and drops can pay off.
