Umpire OVER/UNDER

How Umpire OVER/UNDER Works

What this shows

For every home-plate umpire, how often the combined game total finished OVER or UNDER the closing total line. The leaderboard is one row per umpire; click any name to see their full game log.

Today's Slate

Each of today's games shows its start time and total, the assigned home-plate umpire, and that ump's dominant lean — the side they hit more often (UNDER shown in red for under-leaning umps, OVER in green) with their full O-U-P record and how their games average versus the line. Umpires working the plate today also get a Today badge on the leaderboard. Assignments refresh every 5 minutes as MLB posts officials, and the page updates itself on the same cadence — no reload needed.

OVER / UNDER Rate

OVER% = overs ÷ (overs + unders). Pushes are excluded from the denominator (standard betting convention), so OVER% + UNDER% = 100%. The Games column counts every graded game, pushes included.

Runs vs Line

Average actual combined runs minus the average closing total line, signed. A positive number means this ump's games tend to clear the number; negative means they stay under.

Min games filter & noise

Small samples are noisy. The Min games box (default 40) hides umpires below that count and reports how many were hidden. Umpires under 40 games are muted and flagged with ⚠ whenever they are shown. Umpires scheduled today are never hidden.

Sorting & color

Click any column header to sort (click again to reverse). Default sort is OVER% high-to-low. The OVER% cell is tinted green toward heavy-OVER umps, red toward heavy-UNDER, neutral near 50%.
