MLB Records

Major League Baseball has maintained official records since the National League began play in 1876, with the American League joining in 1901. These records chronicle the greatest individual achievements in baseball history, from Ty Cobb's remarkable .366 career batting average to Nolan Ryan's untouchable 5,714 career strikeouts.

Career records require longevity and sustained excellence over many seasons. Pete Rose accumulated 4,256 hits across 24 seasons, while Hank Aaron chased Babe Ruth's home run record for over two decades before Barry Bonds eventually surpassed both legends with 762 career home runs. These records represent the culmination of entire careers dedicated to the game.

Single-season records capture moments of extraordinary performance. Barry Bonds' 73 home runs in 2001, Ichiro Suzuki's 262 hits in 2004, and Nolan Ryan's 383 strikeouts in 1973 stand as benchmarks that may never be surpassed. The steroid era introduced controversy around some records, leading to ongoing debates about their legitimacy in baseball history.

Pitching records reflect different eras of the game. Cy Young's 511 career wins came during an era when pitchers routinely threw complete games and appeared in over 40 games per season. Modern records like saves (Mariano Rivera's 652) and strikeouts per nine innings reflect how the game has evolved. Some records from the dead-ball era, like Old Hoss Radbourn's 59 wins in 1884, remain untouchable due to fundamental changes in how baseball is played.

Fielding records showcase the defensive wizards of baseball history. Brooks Robinson's 16 Gold Glove Awards, Ozzie Smith's acrobatic plays at shortstop, and Ivan Rodriguez's unmatched durability behind the plate represent excellence in the field. Modern metrics like Defensive Runs Saved and Ultimate Zone Rating help quantify what fans have always appreciated visually about great defenders.

Team records add another dimension to baseball history. The 1906 Chicago Cubs won 116 games, a record later matched by the 2001 Seattle Mariners. The 1927 New York Yankees, often called the greatest team ever, featured Babe Ruth's 60 home runs and Lou Gehrig's 175 RBI. Consecutive game winning and losing streaks, longest playoff droughts, and championship dynasties all form part of baseball's rich statistical tapestry.
