The strategy involves using 'under 0.5 home run' prop bets for MLB players. You look for players with a high likelihood of not hitting a home run, ideally with odds like -1500 or -1000, and parlay a few of these bets together. The key is to select players with a poor batting average against the pitcher they're facing, ideally below .200, with at least 5-10 at-bats and no home runs against them. You then eliminate any players from favored teams to avoid the risk of a high-scoring game. The recommended parlays are two or three-leg parlays to keep the odds manageable and increase the chances of winning.
