Every hits allowed prop the books have posted for George Kirby of the Seattle Mariners, with the MLB game log the number is drawn from. The history below — game by game, split home and away — is measured from official box scores and rebuilt daily. The line and the price load live rather than being printed here, because they change through the day. What the page will not do is tell you the bet wins: it shows you the sample and the price and stops there.
Calculated by the ParlayBuilder Prop Engine.
Every figure on this page is counted from official MLB box scores, one row per game actually played — no projections, and a game the player missed is absent rather than scored as a zero. Hit rates against the live board are shrunk toward a league prior in proportion to how thin the sample is, so three-for-three does not read here as a certainty.
Past performance does not predict future results, and Parlay Builder does not accept wagers, hold funds or settle bets. No locks and no guaranteed wins — this is measured history and a price, and what you do with them is your decision.
You must be 21+ (or older, where your jurisdiction sets a higher age) to bet. If gambling stops being fun, call or text 1-800-GAMBLER for free, confidential help.
It loads live at the top of this page, with the best price across the major US sportsbooks beside it. It is deliberately not printed into the page itself: a line moves through the day, and a page that hard-coded one would keep telling you a number the book no longer offers.
The hit rate beside the line answers exactly that, measured against the exact line on offer over the games in the log below, and shrunk toward a league prior in proportion to how thin that sample is. The game count it is drawn from is printed next to it, because a rate without a denominator is not a measurement.
That depends entirely on the price, and this page will tell you when the answer is no. A prop only clears the research bar with a positive shrunk estimate at the current price, at least ten games behind the rate, a B− grade or better and a price a book has refreshed recently. Most props on most nights clear none of that.
Official box scores, one row per game played, loaded four times a day and rebuilt into this page daily. Games the player missed are absent rather than counted as zero, so the averages describe games they actually played.
