The 2005 MLB season was notable for the league's new steroid policy in the wake of the BALCO scandal, which enforced harsher penalties than ever before for steroid use in Major League Baseball. Several players, including veteran Rafael Palmeiro, were suspended under the new policy. It was also notable that every team in the NL East finished the season with at least 81 wins (at least half of the 162 games played)
Additionally, it was the first season featuring a baseball team in Washington, D.C. since the second iteration of the Washington Senators last played there in 1971; the Washington Nationals had moved from Montreal, the first relocation of a team in 34 years and currently the last time this has occurred in the majors.
The Anaheim Angels changed their name to the Los Angeles Angels of Anaheim.
The season ended when the Chicago White Sox defeated the Houston Astros in a four-game sweep in the World Series, winning their first championship since 1917.
