World Baseball Classic
Ohtani reached new levels when Japan won the World Baseball Classic in 2023. The Championship game was one of the most-watched baseball games ever as Japan defeated the USA. It saw Ohtani face his Angels teammate, Mike Trout, on his way to the Tournament MVP award (via The Guardian).
This was massive for a couple of reasons. Firstly, it elevated the WBC to a new level and interested plenty of neutrals around the world. It was also the first time that many MLB fans saw Ohtani deliver a clutch performance in a playoff-style game. He delivered, as he usually does, in an electrifying event.
