Major league baseball final standings 
The 90 wins by the Diamondbacks and Rockies were the fewest to lead the NL since 1959, with the exception of the strike-shortened seasons of 1981, 1994 and 1995. No NL team won or lost 95 games for the first time since 1983.
Also, this was the second consecutive season in which no team won at least 60% of its games, the first time that this has happened in Major League Baseball history.

- April 15 – To celebrate the sixtieth anniversary of Jackie Robinson's first major league game, dozens of players wear his league-wide retired number, 42. The Los Angeles Dodgers are one of six teams whose entire roster wears number 42 for their games.

- June 4 – Mark Ellis hits for the cycle at McAfee Coliseum as his Oakland Athletics defeat the Boston Red Sox, 5–4 in 11 innings. He hit a triple in the 2nd inning, a solo home run in the 4th and a double in the 6th. Although a fielder's choice in the 8th with the A's holding the lead seemingly ended his run for the cycle, a rally by the Red Sox in the 9th pushed extra innings, allowing Ellis to get the single he needed in the 10th inning.
