What does this SEA @ BOS page show?

Every MatchWiz projection for this game in one place: each hitter's matchup score for hits, home runs, RBIs, runs, walks, stolen bases, total bases, H+R+RBI and fantasy points, and each starting pitcher's strikeout and pitcher-prop projections — with the live box score graded against every one of them (✓ hit / ✗ miss) as the game plays.

How often does the live data update?

Our poller checks every in-progress game roughly every 45 seconds. The score, inning, and every player's live line on this page refresh automatically — no reload needed.

What do the matchup scores mean?

Each score is 0–100, ranking that player's conditions for that stat against the full slate — driven by batter-vs-pitcher-hand splits, recent form, park and weather, lineup spot and workload. See "How it works" for the full methodology and our graded season record.
