A +1.5 spread is commonly seen in baseball betting, the standard runline  for MLB. This spread means the underdog must win outright or lose by exactly one run to cover the spread. Alternatively, a -1.5 spread means that the favorite must win by at least two runs. Many baseball games are decided by fewer than two runs.

Our computer model analyzes every bet, every day to find mispriced lines. The model projects team performance and takes into account player performance, matchups, weather and injuries. From there, we set our own line, compare it with vegas and assign a star rating to each game.
