10 Worst Umpires in Major League Baseball
6. Laz Diaz
Diaz is a fixture on these list and for good reason: he's terrible. In fact, some might say we have him far too low on the list. The 60-year-old has been an MLB ump since 1995, is a crew chief and has worked three World Series. We're shocked by those facts, but we're also just shocked he still has a job.

Umpire Laz Diaz called one of the worst games I've ever seen.
He missed 20 calls (4 of those were strikeouts) and 16 went against the #Pirates. His stats were terrible, but somehow the video looks even worse.

In 21 games behind the plate in 2023, Diaz's accuracy was 92.9, which ranked sixth-worst in the league. His CCAx of -29.6 was fifth-worst, his AAx was -0.97, which was second-worst in the bigs. Diaz had 10 games with 10 or more missed calls and four with 16 or more. He's just flat-out bad.
