Tony Gwynn's highest batting average for a season was .394, achieved in 1994.
Gwynn hit .39379 for the San Diego Padres, which is recorded as .394 after rounding. He collected 165 hits in 419 at-bats over 110 games and won the National League batting title, his fifth overall. The season was shortened by the players' strike, ending in August.
The performance was especially remarkable because Gwynn briefly challenged the possibility of hitting .400, a feat last achieved by Ted Williams in 1941. Gwynn finished just short, but his .394 remained the highest major-league single-season batting average since Williams' .406.
A common mix-up is confusing Gwynn's .394 with his career batting average, which was .338. The .394 figure refers only to his extraordinary 1994 season, not his complete 20-year career.
