FREQUENTLY ASKED QUESTIONS
How far back does the season data go?

What happened to the 1994 season?
The 1994 season was shortened by a players' strike that began on August 12, 1994, resulting in cancellation of the remainder of the season and the postseason. It remains the only year the World Series was not played since 1904.
Which season had the most home runs hit?
The 2019 season set a new MLB record with 6,776 home runs hit across both leagues, surpassing the previous record set in 2017. Multiple factors including a juiced ball and increased launch angle batting approach contributed to the surge.
What seasons had the most dominant pitching?
The 1968 season is known as the "Year of the Pitcher," with Bob Gibson's historic 1.12 ERA and Denny McLain winning 31 games. Batting averages league-wide dropped so dramatically that MLB lowered the pitcher's mound the following year.
