Which hitters have a platoon edge today?

Hunter Goodman (COL) — righty bat vs LHP, .164 against lefties this year. Yordan Alvarez (HOU) — lefty bat vs RHP, .179 against righties this year. Jonathan Aranda (TB) — lefty bat vs RHP, .168 against righties this year. Brandon Lowe (PIT) — lefty bat vs RHP, .189 against righties this year. Jackson Merrill (SD) — lefty bat vs RHP, .103 against righties this year.

How is the rbis matchup score calculated?

It's a weighted read of the hitter's RBIs 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 RBI/PA mean?

It's the share of a hitter's trips to the plate that drive in a run. Around .105 is league average. RBIs lean on lineup spot and who's on base ahead of you, so we weigh the matchup but it's a noisier market than hits.

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 RBI.

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 RBI.

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 RBI 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 rbis 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+ RBI" 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 RBI 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 RBIs Matchups — Monday, August 3, 2026

Osleivis Basabe (SF) is the top rbis matchup on the Monday, August 3, 2026 board at 100, with Jake McCarthy (COL) and James McCann (AZ) right behind. Every hitter on the slate is ranked by the best RBI matchups — who's set up to drive in runs — run-producing bats, the arm and bullpen they face, batting order, park, and weather. It's the read DFS and prop players make before lock.

Top rbis spot: Osleivis Basabe

Osleivis Basabe (SF) tops the board at 100, facing RHP Cal Quantrill. The righty is driving in runs at .714 RBI/PA against righties this year — and .714 over the last two weeks, an elite bat that turns into a RBI in about 21% of his trips. And Cal Quantrill has been getting lit up by righties lately — .250 RBIs per batter faced. One catch: the bullpen behind him has been stingy to that side late. He's hitting in a spot worth about 4.0 trips, so the volume's there. He's just .000 in 2 career PA against Cal Quantrill, but that's a tiny sample and the matchup says regression. It all sets up in a neutral park.

The rest of the top of the board

Jake McCarthy (COL) (100) vs LHP Ian Seymour: an excellent bat at .152 into an arm stingy with runs against the same side (.000).
James McCann (AZ) (100) vs RHP Michael King: an elite bat at .192 into an arm stingy with runs against the same side (.000), hot bat.
Kazuma Okamoto (TOR) (97) vs RHP Cristian Javier: an excellent bat at .160 into an arm stingy with runs against the same side (.000).
Hunter Goodman (COL) (97) vs LHP Ian Seymour: an elite bat at .165 into an arm stingy with runs against the same side (.065).
Manny Machado (SD) (96) vs RHP Brandon Pfaadt: an excellent bat at .160 into an arm stingy with runs against the same side (.048), due to bounce back.
Yordan Alvarez (HOU) (92) vs RHP Shane Bieber: an excellent bat at .157 into an arm getting lit up by the same side (.150).
Junior Caminero (TB) (90) vs RHP Michael Lorenzen: an excellent bat at .146 into an arm getting lit up by the same side (.200).

Platoon edges to target

Hunter Goodman (COL) — righty bat vs LHP, .164 against lefties this year.
Yordan Alvarez (HOU) — lefty bat vs RHP, .179 against righties this year.
Jonathan Aranda (TB) — lefty bat vs RHP, .168 against righties this year.
Brandon Lowe (PIT) — lefty bat vs RHP, .189 against righties this year.
Jackson Merrill (SD) — lefty bat vs RHP, .103 against righties this year.

How it played out

7 of the top 10 rbis matchups landed at least one RBI. Top play Osleivis Basabe finished with 1 RBI. 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 rbis matchups

Each score (0–100) starts with the hitter's RBIs 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 RBIs board is

The RBIs board projects the chance a hitter drives in a run, given his slot and the bats around him. 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 run-driving rate.
How often the hitters ahead of him are on base.
The arm he faces and the park.

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?

RBIs is lumpy — runs cluster — and once you price the 1+ line with a clustering-aware model instead of a naive one, the apparent edge vanishes. It grades efficient. So this is a transparency board.

How to use it

Good for spotting the cleanup-spot smash setups; not a market we've found a bettable edge in.

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