In this FantasyPros fantasy baseball mock draft, the crew jumped into a 5×5 roto build with 15 teams, four active outfielders, and no bench. Categories were standard: HR, RBI, R, SB, AVG on the hitting side, and W, SV, K, ERA, WHIP for pitching. That format alone changes everything. Scarcity hits faster. Position runs get real. And if you miss on a pocket of value, the board gets dark in a hurry.

Fantasy Baseball Mock Draft: 15-Team Roto
Here’s what stood out from the fantasy baseball mock draft strategy discussion and how it should shape your own 2026 draft plan.
Third Base Scarcity Is Real in 15-Team Leagues
The first pivot of the draft came early when Jose Ramirez went second overall over Aaron Judge.
In a 12-team league, that might feel aggressive. In a 15-team league with corner infield spots and no bench? It’s defensible.
The reasoning was simple:
- Third base thins out quickly.
- Ramirez provides elite power-speed balance.
- You avoid chasing risky mid-tier options later.
In deeper formats, locking up a premium third baseman creates flexibility. You’re not scrambling for a Matt Chapman type three tiers later. You’re building from strength.
- Lesson: In 15-team roto, relative position value matters more than brand name. Elite scarcity wins.
First-Round Pitching: Risky or Smart?
Welsh tested an early pitching strategy by grabbing Paul Skenes in the first round.
This wasn’t about talent. It was about roster construction.
In roto, especially with potential innings caps, elite strikeout arms give you:
- Category insulation in Ks
- Strong ratio foundation
- Less pressure to chase volume later
The downside? The offense behind it gets trickier. After going Skenes, the build required balancing batting average and stolen bases aggressively.
- Lesson: First-round pitching works in 15-team roto, but it forces you into category management mode immediately.
Closer Strategy: Don’t Punt Saves Blindly
In shallower leagues, punting saves is trendy. In 15-team roto, it’s dangerous.
Kelly grabbed Mason Miller early. Welsh locked in Edwin Diaz. The logic:
- Saves dry up fast.
- Committees are unpredictable.
- One elite closer stabilizes ERA, WHIP, and strikeouts.
Later, teams that waited had to reach for speculative options.
- Lesson: In deeper roto, securing one reliable closer early gives you flexibility later. You don’t need two elite guys, but you probably need one anchor.
Power vs. Speed Balance Is Harder Than It Looks
One of the more interesting builds stacked power early with Schwarber and Suarez, then corrected with Chandler Simpson.
That’s classic roto balancing:
- Lock in 40-HR bats.
- Backfill steals with elite speed specialists.
Simpson may offer minimal power, but if he leads the league in steals, he offsets category imbalance instantly.
The key is intentionality. If you draft two low-average sluggers, you need to counter with contact hitters or elite speed.
- Lesson: In roto, extremes are manageable if planned. Unplanned category holes are fatal.
Bounceback Bets With Massive Upside
Fifteen-team leagues reward upside shots in the middle rounds.
- Cruz brings 20 HR / 40 SB upside despite batting average risk.
- Merrill is a post-hype candidate who could rebound in a loaded lineup.
- McClanahan, two Tommy Johns deep, still carries SP1 upside if healthy.
In deeper leagues, these gambles are necessary. Safe mediocrity won’t win 15-team roto.
- Lesson: You need ceiling somewhere. Just make sure it’s paired with stability elsewhere.
Position Flexibility Is a Hidden Weapon
Players like:
Multi-position eligibility matters more in deeper formats because:
- Waiver replacement value drops.
- Injuries hit harder.
- Streaming options are limited.
The ability to move pieces around your infield and outfield can prevent zeroes and maximize category matchups.
- Lesson: In 15-team roto, flexibility is roster insurance.
When the Pitching Pool Gets Ugly
A big theme from the episode: once you miss your pitching pocket, it falls off fast.
After the Freddy Peralta / Eury Perez / Nolan McLean tier, the room got uncomfortable quickly. That forced pivots to closers or risky arms.
This is where pre-draft prep matters most. Know your tiers. Know your breakpoints. Don’t rely solely on ADP.
Fantasy Baseball Mock Draft Takeaways
- In 15-team roto, positional scarcity matters more than name value.
- Locking in one elite closer stabilizes your pitching build.
- First-round pitching can work, but it demands immediate category balance.
- Extreme power builds require intentional speed backfills.
- Post-hype hitters and injured aces are viable mid-round upside plays.
- Position flexibility is more valuable in deeper formats.
- Know your pitching tiers. Missing a run can derail your build.
If you’re preparing for 2026 drafts, don’t just mock 12-team leagues. Push into 15-team formats. The discomfort forces sharper decisions and clearer target priorities.
