Alex MacKay has 110 home-plate games in our MLB database. His games average 8.13 combined runs against a league average of 8.89 — the tables below break that down by season and show his most recent games. Umpire tendencies are one small input to our MLB totals model, never a betting rule on their own.
No upcoming plate assignment on record — MLB publishes umpire crews on game day, so check back in the afternoon (US time).

Method: every number on this page is computed from the finished MLB games in our own model database (2022 onwards) where Alex MacKay was the recorded home-plate umpire. "Over 8.5 %" is the share of his games with 9+ combined runs; "Home win %" is how often the home team won with him behind the plate. Only umpires with at least 30 plate games get a page — smaller samples are noise. One honest caveat applies to everything here: even several seasons of plate games is a modest sample, and most deviation from the league average is variance, not a hidden edge.
