Today's HR Watch is a free daily board that ranks the hitters on the MLB slate by their chance of hitting a home run today. Each bat gets a home-run likelihood score built from season power rate, the opposing starting pitcher's HR/9, the ballpark's home-run environment, and recent form — so you can quickly see who's set up to go deep.
Filter the board to hitters who homered yesterday. Day-to-day repeats are mostly noise, but pairing a fresh home run with a strong matchup and a hitter-friendly park is a useful watch signal, not a promise.
Some hitters bunch their home runs — back-to-back games and multi-homer nights. The cluster-history flag surfaces bats that have shown that streaky home-run pattern this season, with the evidence (HRs in the last five games, back-to-back games, multi-HR games) shown on each card.
The board combines a hitter's home-run rate and isolated power (ISO) with the opposing pitcher's home runs allowed per nine innings, the ballpark factor, and recent form into a single 0–100 likelihood score. It is research and entertainment, not a guarantee or betting advice.
Not reliably. Back-to-back home runs happen, but a single home run is a weak predictor of the next day. Use it as one input alongside the matchup score and park factor.
A cluster is a stretch where a hitter homers in bunches — several home runs across a few games, back-to-back home-run games, or multi-homer games. Cluster-prone bats are worth watching during hot streaks.
