Over 29 logged MLB games, Kenley Jansen has gone over 0.5 strikeouts 20 times (69%), and over their last 10 they have done it 7 times (70%). They average 1.0 strikeouts across those 29 games. Their last 5 average 1.2, 20% above their 1.0 across the full log.

Kenley Jansen of the Detroit Tigers in strikeouts, measured from official MLB box scores rather than from anybody's projection. The table above is their hit rate at every threshold their own distribution supports, over three nested windows, each with its own denominator. Below it are the games themselves. No line or price is printed on this page; when the board carries one, it loads live above this text and this history is what it will be measured against.
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. Where a hit rate is compared with the live price, it is first pulled toward that price 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.
None is printed on this page, which is why this page shows thresholds drawn from their own game log instead. Those are facts about games already played and they do not go stale; a line does, which is why one is never printed into a cached page here.
The table above answers that at every threshold their log supports, over all their logged games and over the last ten and five, so a recent run and a full record can be read side by side rather than confused for each other.
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 were actually in.
