Laz Diaz has long been known as not great as a ball-and-strike umpire.
Regardless, there he was Tuesday night, calling balls and strikes in Game 4 of the ALCS between the Red Sox and Astros.
And his Game 4 ball-and-strike calls were worse than usual. Just how bad were they?
Home-plate umpire Laz Diaz has missed 21 ball-strike calls tonight, according to @ESPNStatsInfo. That is the most of any umpire this postseason. The green dot in the upper RH corner is the Eovaldi curveball that would've ended top of the ninth with the score 2-2.
