Initial reception by American media
Ohtani's debut MLB spring training in 2018 was disastrous and the majority of American news sources were extremely disappointed, concluding that he could not accomplish even one of his two-way abilities.

He completed his five game spring training, three of which against minor leaguers, with an 11.7 ERA in pitching, and 4 hits for 32 at bats,125/.222/.125 in batting (batting average/on-base percentage/slugging percentage, averaged .248/.318/.409 for MLB batters that year.
