The run line is MLB's version of the point spread — almost always set at 1.5 runs — and it reshapes the price you pay on a favorite or underdog.
Baseball is low-scoring, so its standard spread is fixed at 1.5 runs in nearly every game. The favorite is laid at -1.5, meaning it must win by two or more runs to cover. The underdog gets +1.5, meaning it covers by winning outright or losing by exactly one run.
Because the spread is fixed rather than tailored to each matchup, the price attached to the run line does the adjusting. A heavy favorite at -1.5 will often pay plus money, while the +1.5 underdog is laid at a price.
The moneyline is a straight bet on who wins. The run line adds the 1.5-run margin. Taking a strong favorite on the run line is a way to get a better price than the steep moneyline, at the cost of needing a two-run win. Taking an underdog on the moneyline pays more but requires an outright upset; the +1.5 run line trades some of that payout for the cushion of a one-run loss still cashing.
Run-line betting splits are read the same way as any other market: compare the share of tickets to the share of dollars. A run line drawing most of the bets but a minority of the money is a public-favorite profile, just on the spread instead of the moneyline.

No. Fading works when the public lean is heavy enough to move the line off the true number. On games with balanced action, there is no edge to fade.
Public favorites still win plenty of games — they are usually the better team. Where the public underperforms is against the spread on big-name teams in nationally televised games.
