Backyard BaseballThe Backyard Baseball franchise has always featured real MLB players reimagined as kids — and the 2026 reboot continues this beloved tradition. Seven unlockable MLB pros join the 30 original Backyard Kids, bringing their real-world stats and skills to the backyard diamond. This guide covers every MLB pro with their in-game stats, unlock conditions, and strategic value for your team.
The MLB Pros Tradition
Since the original 1997 game, Backyard Baseball has featured real Major League Baseball players as unlockable characters. The original game included legends like Barry Bonds, Randy Johnson, and Alex Rodriguez as kid versions. The 2026 reboot continues this tradition with seven new MLB pros, chosen to represent different eras and positions of baseball greatness.
The key difference between MLB pros and the 30 Backyard Kids is that pros must be unlocked through gameplay progression. You cannot draft them on day one — they require specific achievements or milestones to become available. This makes them valuable long-term goals that extend the game's progression system.
Historical Context
The original Backyard Baseball (1997) featured 10 MLB pros, including Sammy Sosa, Mark McGwire, and Ken Griffey Jr. Later entries in the franchise changed the roster based on licensing availability. The 2026 reboot faces similar licensing challenges — some original pros may have been replaced with different players due to rights issues. Community reports are still confirming the exact roster.

MLB Pros vs Backyard Kids Comparison
How do the unlockable MLB pros compare to the 30 original Backyard Kids? The answer depends on your roster needs and the specific pro in question.
Overall Tier Comparison
| Character Type | Average Batting | Average Pitching | Average Running | Average Fielding |
|---|---|---|---|---|
| MLB Pros (7) | ~7.7/10 | ~5.1/10 | ~6.1/10 | ~7.0/10 |
| Backyard Kids S-A Tier (4) | ~8.0/10 | ~7.0/10 | ~8.0/10 | ~7.5/10 |
| Backyard Kids B Tier (12) | ~6.0/10 | ~5.8/10 | ~5.9/10 | ~5.9/10 |
| Backyard Kids C Tier (7) | ~4.1/10 | ~3.7/10 | ~4.7/10 | ~3.9/10 |
MLB pros are generally comparable to A tier Backyard Kids — strong in their specialty areas but not as well-rounded as Pablo Sanchez. Chipper Jones and Derek Jeter are the most versatile pros, while Mark McGwire and Randy Johnson are extreme specialists.
Where MLB Pros Excel
MLB pros excel in specific niches. Randy Johnson at 9/10 pitching matches Kenny Kawaguchi as the best arm in the game. Ichiro's 9/10 running approaches Pete Wheeler's 10/10 speed. Mark McGwire's raw batting power rivals Pablo Sanchez's 10/10 for home run frequency. These specialists fill roster gaps that the Backyard Kids cannot.
Where Backyard Kids Excel
The Backyard Kids have chemistry effects that MLB pros lack. The Khan brothers buff, the Webber twins synergy, and the Dobbs siblings chemistry (for better or worse) add strategic depth that pros cannot match. Additionally, Pablo Sanchez remains the best overall character in the game, with stats that no MLB pro can match across all four categories. This means that while MLB pros fill important roster niches, they cannot replace the strategic value of chemistry-paired Backyard Kids in a well-constructed roster.
Unlock Priority Strategy
Since you cannot unlock all seven MLB pros simultaneously, you need a strategy for prioritizing which pros to target first. Here is our recommended unlock order based on strategic impact:
- Randy Johnson (first priority) — A second 9/10 pitcher transforms your rotation
- Ichiro Suzuki (second priority) — 9/10 running + 8/10 batting = elite leadoff
- Chipper Jones (third priority) — Versatile switch-hitter with strong all-around stats
- Derek Jeter (fourth priority) — Complete player with leadership intangibles
- Mike Piazza (fifth priority) — Power-hitting catcher fills a niche
- Mark McGwire (sixth priority) — One-dimensional power bat
- Sammy Sosa (seventh priority) — Similar to McGwire but slightly less impactful
