What we can't say about Jeremie Rehak

This season is 3,178 graded takes, which puts Jeremie Rehak's overall accuracy at 93.2% ± 0.9 (95% interval). That is a real measurement against a league spanning about four points end to end. It is not enough for anything finer, and here is the arithmetic rather than our word for it:

  • how the zone moves with two strikes about 636 takes, so ±2.0 points. (the league-wide two-strike effect is about 1 point in 2026.)
  • any single corner of the zone about 265 takes, so ±3.0 points. (corner cells are where umpires actually differ.)
  • whether one pitcher is called tighter than another about 53 takes, so ±6.8 points. (a given pitcher is worked once or twice a season.)

And a note on the number itself: an accuracy figure is a rate plus a convention for what counts as a miss. Ours grades every taken pitch against the rulebook zone as the feed reports it. Others are more forgiving — UmpScorecards counts a call wrong only when the pitch was at least 90% likely to be a strike — so two sites can print the same percentage about the same umpire and not mean the same thing by it. How the grade is built.

The overturn rate is a different kind of number and does not belong beside the grade: it is accuracy on the 89 pitches players chose to challenge, which are the pitches they already believed were wrong. 89 is enough to print it with its own denominator, which is what we do — but it still ranks umpires by how often they are appealed, not by how often they are right.

The road to the plate

Jeremie Rehak

A walk-on ballplayer at Ohio University who climbed the minor leagues and 281 call-up games before reaching the full-time MLB staff.

Before he called a pitch in the major leagues, Jeremie Rehak tried to hit a few. He played three seasons as a walk-on for the Ohio University Bobcats, starting as an infielder before shifting to the outfield. The Murrysville, Pennsylvania, native and Franklin Regional High School graduate later attended the Hunter Wendelstedt Umpire School, graduating in 2011.

His minor-league work included the Gulf Coast, Appalachian, Midwest, California, and Eastern Leagues before he reached Triple-A. His first major league game came on April 9, 2018, in Kansas City. He accumulated 281 games of major league experience as a call-up, and the UEFL named him Fill-In Umpire of the Year in both 2018 and 2020. MLB hired him to its full-time staff in December 2020.

The postseason assignments have followed the tenure. He worked Division Series in 2022 and 2025, Wild Card Series in 2023 and 2024, a Championship Series in 2024, and earned selection to the 2025 All-Star Game. As of 2023, he was one of only five African-American umpires in the major leagues — a small group in a sport where Emmett Ashford broke the color barrier generations earlier and, for most years after, only one or two African-American umpires worked at the MLB level.

He wears uniform number 35 on a crew headed by chief Dan Iassogna, alongside C. B. Bucknor and Adam Beck. His 17 graded games behind the plate this season are what put his name on this page.
