Questions
How often did MLB player prop overs clear on September 21, 2026?
In 474 of 2,834 graded overs (16.7%), at every line any book posted across 15 markets. A count of that day's graded outcomes, not a prediction.
Which MLB market cleared most often that day?
Outs recorded: 15 of 34 graded overs (44.1%). The lowest was stolen bases: 1 of 98 (1%). Higher lines clear less often by construction, so a market's rate depends on the lines the books chose to post.
Are these DataStreak picks?
No. Every row is a market outcome: a prop line a sportsbook posted, graded off the official box score by the data vendor, counted whether or not anyone bet it. DataStreak does not produce picks and this page is not a record of any.
How this is measured
The data vendor grades every player prop line a sportsbook posted against the official box score: over, under, push or void. This page counts the OVER side of every graded MLB line for games on this ET date, at every line any book posted, whether or not anyone bet it. Pushes and voids are excluded from both counts. No selection of DataStreak's is involved: this describes the market on one day, not anyone's picks. A rate is an outcome frequency at posted lines, never a probability for another day.
