MLB SMASH v2 is powered by a Cloudflare Worker that proxies MLB Stats API + Baseball Savant for faster loads and richer data (xBA, xwOBA, barrel%).
Tiers:
HR Parlay tab — three strategies:
Multi-Parlay tab (new): Track multiple season-long 3-player HR parlays simultaneously. Get AI-recommended trios in 4 categories (Power / High-Avg / Park-Friendly / Cheap-Odds) or build your own. Each parlay shows season EV projection ($10/bet) and daily Strategy C verdict. Players don't need to be playing today — assessment begins once locked in.
Backtest: Pick a date range from a past season, the tool replays the model and reports hit rate by tier and ROI assuming average odds. Use this to validate the model before risking money.
Data caveats: No free player prop odds feed exists — props are confidence tiers, not -EV/+EV. Cross-reference with your book.
