—Letter grades (ACF) are confidence, not quality — how large the sample behind that number is. They say nothing about how good the hitter is.

Edge
Where our model and FanDuel's line disagree most. FanDuel% is a single book's raw implied probability, not devigged against a two-sided line (FanDuel doesn't price a "0 HR" side for this prop) — read it as one sportsbook's number, not a market consensus. This isn't a "bet this" list either way — a big edge can mean we caught real signal FanDuel underweights, or it can mean the book knows something we don't (see the negative-edge side too). Treat it as worth a second look, not an instruction.
