How is the walks matchup score calculated?

It's a weighted read of the hitter's walks per plate appearance against the hand he's facing — the last two weeks, the current season, and a two-year baseline, with recent form counting most. Then it folds in the opposing bullpen, his expected plate appearances from the batting order, and park and weather. Scores are set 0–100 across the day's slate, so the best matchup is always 100.

What does BB/PA mean?

Walks per plate appearance — how often a hitter draws a base on balls. Around .085 (one walk every ~12 trips) is league average; .12+ is elite plate discipline. The matchup pairs the hitter's walk rate with how freely the pitcher gives them up.

What does the score actually mean?

Higher is better for the hitter. 80s and 90s mean the bat, the pitcher, and the park all line up. 40s and 50s mean it's neutral to tough. It's a ranking of how today's spots stack up against each other — not the odds of a walk.

What's the confidence meter?

It's how much data is behind the call — sample size on both the hitter and the pitcher, plus whether the lineup's official. A high score with low confidence is a thinner read than the same score backed by a deep track record. It's not a probability of a walk.

What is a platoon split (handedness split)?

Most hitters do better against the opposite hand — a lefty bat vs. a righty arm, and vice versa. That gap is the platoon split. The score leans hard on each hitter's rate against the hand he's facing today, which is why the same guy can rank very differently day to day.

What are park factors?

Parks aren't neutral. Dimensions, altitude, and weather make some easier to hit in than others. Above 1.00 bumps the score, below 1.00 trims it — same hitter, higher grade in a hitter's park than a pitcher's.

What do "2W", "SZN" and "2Y" mean?

The timeframes behind each rate: the last two weeks (recent form), the current season, and a trailing two years (a stable baseline). Recent form counts most, and small samples get pulled toward league average so a hot week doesn't fool the model.

What do "≈ est", "Due" and "Not starting" mean?

"≈ est" is a hitter we don't have splits for yet — a rookie or unmatched ID — shown at a league-baseline estimate instead of dropped. "Due" means he hasn't recorded a walk in a while and profiles for regression. "Not starting" means he was projected but didn't make the official lineup, so he slides to the bottom where you can still look him up.

Can I use this for walks props or DFS?

That's what it's built for — pre-slate research. The board surfaces which hitters have the best conditions today, and where one exists, we show the book's "1+ walk" line so you can shop the price. We're not a sportsbook and we don't post picks — we show the matchup data, the line, and the result. (Best-price and all-book odds are a Pro feature.)

How accurate is the model?

We grade every board against real results, and the top of the board lands a walk a lot more often than the slate as a whole. Weights get re-tuned weekly against actual outcomes on a held-out split, and since results sit next to projections, you can audit the hit rate yourself on any past date.

When do lineups update?

Projected lineups (marked "Proj") come from each team's last game. Official lineups usually drop about two hours before first pitch, and the board updates itself as they post. Batting order is a big driver, so it's worth a second look mid-afternoon — rankings shift as lineups lock.

Best MLB Walks Matchups — Monday, August 3, 2026

Yordan Alvarez (HOU) is the top walks matchup on the Monday, August 3, 2026 board at 100, with Geraldo Perdomo (AZ) and James Wood (WSH) right behind. Every hitter on the slate is ranked by who's most likely to draw a walk — plate discipline and how freely the pitcher and bullpen issue walks, plus lineup spot. It's the read DFS and prop players make before lock.

Top walks spot: Yordan Alvarez

Yordan Alvarez (HOU) tops the board at 100, facing RHP Shane Bieber. The lefty is working counts at .181 BB/PA against righties this year — and .167 over the last two weeks, an excellent bat that turns into a walk in about 15% of his trips. And Shane Bieber has been handing out free passes to righties lately — .200 walks per batter faced. The bullpen behind him is roughly average to that side. He's hitting in a spot worth about 4.5 trips, so the volume's there. He's owned Shane Bieber too — .500 across 8 career trips. It all sets up in a neutral park.

The rest of the top of the board

Geraldo Perdomo (AZ) (100) vs RHP Michael King: an excellent bat at .132 into an arm handing out free passes to the same side (.135).
James Wood (WSH) (90) vs RHP Aaron Nola: an elite bat at .154 into an arm handing out free passes to the same side (.125), due to bounce back.
Corbin Carroll (AZ) (81) vs RHP Michael King: a solid bat at .095 into an arm handing out free passes to the same side (.135).
Max Kepler (AZ) (76) vs RHP Michael King: a strong bat at .102 into an arm handing out free passes to the same side (.135), due to bounce back.
Brice Turang (MIL) (76) vs RHP Bubba Chandler: a strong bat at .113 into an arm fairly stingy with walks against the same side (.083), hot bat.
Trent Grisham (NYY) (71) vs RHP Michael McGreevy: a strong bat at .108 into an arm handing out free passes to the same side (.174), due to bounce back.
Ben Rice (NYY) (67) vs RHP Michael McGreevy: a strong bat at .106 into an arm handing out free passes to the same side (.174), due to bounce back.

Platoon edges to target

Yordan Alvarez (HOU) — lefty bat vs RHP, .181 against righties this year.
Geraldo Perdomo (AZ) — lefty bat vs RHP, .157 against righties this year.
James Wood (WSH) — lefty bat vs RHP, .198 against righties this year.
Corbin Carroll (AZ) — lefty bat vs RHP, .117 against righties this year.
Max Kepler (AZ) — lefty bat vs RHP, .095 against righties this year.

How it played out

4 of the top 10 walks matchups landed at least one walk. Top play Yordan Alvarez finished with 2 walks. We post the result next to every projection so you can grade the board yourself — and so the model gets re-tuned against what actually happened.

How to read these walks matchups

Each score (0–100) starts with the hitter's walks per plate appearance against the hand he's facing — weighted toward the last two weeks, then the season, then a two-year baseline. Then it layers in the bullpen, his spot in the order, and park and weather. Higher means more of it points his way. It's context, not a lock — a great spot still goes 0-for-4 sometimes, and a tough one runs into one. The edge is in stacking the odds, and since we grade every board, you can see how often the top of the list delivers.

What the walks board is

The Walks board projects the chance a hitter draws a walk. One statistical model scores every matchup on the slate the same way — a star and a backup judged on the matchup in front of them, not their name — and every number is graded against the real box score once the games go final.

How the model gets its number

It isn't a gut call or a name game. The projection is built from a few things:

His plate discipline.
The pitcher's control.
The count leverage in the matchup.

Those pieces combine into one number, and the model re-tunes itself weekly against how its past calls actually landed.

Is there a betting edge here?

An over-only market with heavy juice; our overs grade anti-predictive and lose to the vig. No edge — transparency board.

How to use it

Spot the patient-hitter-vs-wild-arm setups; not a bettable edge.

Everything here is a research signal from the model, graded in public — not betting advice, and no outcome is guaranteed.
