How the Gamecast Works

Every player row expands

Batters · starters · relievers, pregame and live

Tap any batter, either starter, or a bullpen arm and a WHAT TO WATCH dropdown opens: up to three stat-note talking points graded against league average. Hitters add vs-LHP / vs-RHP wRC+ splits so you can see tonight’s platoon matchup at a glance.

Expand a pitcher and you get a catcher-view strike zone with his last 50 pitches plotted and clustered by pitch type, so you can see where he actually throws the ball. The legend lists each pitch with usage, average velocity and movement, and the vs LHB / vs RHB tabs show how the mix changes by batter hand.

Scheduled scoreboard

Gold SCHEDULED pill · first pitch time · venue & weather

The team-colored stripe under the score is the model’s pregame win probability for each club.

The stripe under the score: away chance on the left, home on the right, filled in each club’s color. Pregame it opens at the model’s odds, then moves on every play.

Five swipeable tabs

MATCHUP · BULLPEN · TRENDS · PREDICT · DEEP CUTS

Both nine-deep lineups measured against the opposing starter’s hand. Tap any batter or either starter to expand a dropdown of stat-note talking points, plus vs-LHP / vs-RHP wRC+ splits for hitters.

Every reliever’s last-3-days workload as a stacked vertical bar, grouped into lefties and righties with ERA under each name. Yesterday’s pitches sit at the base of the bar in white; pitches from 2-3 days ago stack above in orange, so bar height is the full 3-day load. Bold names are fresh arms: nothing yesterday and a light 3-day total. Dimmed columns are gassed arms, either a heavy outing yesterday or back-to-back days (flagged B2B in red). Tap any arm and it opens the same drilldown the starters get: percentile bars, the pitch legend and last-50 map, and talking points.

Recent form: each club’s last five results, both starters’ last three starts, and both leadoff men’s last-7-game slash lines.

A Monte Carlo simulation of tonight’s game: win odds, expected runs and the full run distribution, with venue and weather underneath.

Every league-wide leaderboard (a “board”) where either of tonight’s clubs ranks top-five or bottom-five. Each board carries a green TOP 5 or red BOTTOM 5 tag, the club’s absolute league rank so you know exactly where they sit (say #28 of 30, not just “bottom-five”), and the sample count behind the stat so you know how much to trust it. It is the fastest way to find the hidden storylines behind the matchup.

Live scoreboard

Red LIVE pill · inning & outs · at-bat state

Between the two scores: occupied bases in gold, the ball-strike-out pips underneath, and a sprint-speed arc on every runner.

Runners on 1st and 2nd, one out, 2-1 count. Gold squares are occupied bases; the colored arc on each runner is sprint speed. A wide red arc is a burner, a short blue one is station-to-station.

The most recent play’s description runs under the win-prob stripe, and bolds with a red HI LEV chip when the leverage index says the moment is big.

When a play completes, a broadcast banner wipes across the scoreboard: the event, the final pitch on a mini strike zone, xBA / exit-velo / distance chips, where the ball landed, and how the runners moved. Scroll down and a compact sticky scoreboard pins to the top with the same wipe.

The page polls MLB’s raw feed, which usually runs ahead of your TV or stream. The TV SYNC strip delays everything on the page in 5-second steps so nothing gets spoiled.

Four swipeable panels

MATCHUP · LAST 50 · STRIKE ZONE · WIN PROB

The current batter vs pitcher, keyed to the opposing hand: hot zones and percentile bars up front, season and today’s lines on each player, and the live strike zone with every pitch of the at-bat plotted.

The header of either player expands a “What to Watch” dropdown with up to three stat-note talking points. The pitcher’s dropdown adds his pitch legend and a map of his last 50 pitches against this batter’s hand.

LAST 50 is the batter’s recent batted balls sprayed onto the actual park’s dimensions; STRIKE ZONE is the full-size zone with pitch-type colors and outcome rings.

The live win-probability curve on a cream chart panel, colored by whichever club is on top, with inning ticks, a leverage-index bar chart underneath, and the top three “key swings” listed below.

Five tabs at the foot of the page

AT BAT · PLAYS · TEAM STATS · BOX · GAMES

Every play of the game, ranked By WPA (biggest swings first) or flipped to Chronological. Each row carries the batter-vs-pitcher line, exit velo / launch angle / distance / xBA, runner movement, a mini spray dot, the score after the play, and a Savant video link when there is one.

The line score plus a side-by-side team comparison, and “Tonight’s Bats”, the hitters sorted by how much win probability they’ve personally added or burned.

A traditional box score with away/home tabs: full batting and pitching tables, an ON MOUND chip on the current pitcher, and a per-inning scorekeeping view.

Tonight’s full slate, sorted live → upcoming → final, so you can hop to any other game without going back to the scoreboard. A ticker of other scores and a pitcher wire strip run just above the tabs.

Recap mode

RECAP · DECISIONS · TOP PLAYS · MATCHUP

A written recap headline plus the final win-probability chart. DECISIONS lists the winning and losing pitchers and the save; TOP PLAYS keeps the full WPA-ranked play list; the eye icon flips back to the pregame preview if you want to see how the forecast aged.
