• Dallas Braden (OAK):
  • Threw the 19th perfect game in Major League history, defeating the Tampa Bay Rays 4–0 on May 9, Mother's Day in the USA.

• Roy Halladay (PHI):
  • Exactly 20 days later, on May 29, Halladay threw the 20th perfect game in Major League history, defeating the Florida Marlins 1–0.

In 1880, both Lee Richmond and John Montgomery Ward both hurled a perfect game five days apart.

  • Galarraga threw what would have been a third perfect game on June 2 against the Cleveland Indians. However, first base umpire Jim Joyce made an errant call on Galarraga's coverage of first base on a flip throw by first baseman Miguel Cabrera, which would have been the final out. "I just cost [Galarraga] a perfect game", Joyce replied. "I thought he beat the throw. I was convinced he beat the throw, until I saw the replay. It was the biggest call of my career. I don't blame them a bit or anything that was said. I would've said it myself if I had been Galarraga. I would've been the first person in my face, and he never said a word to me." The 17,738 fans—as well as players and manager Jim Leyland—argued following the game.[11]

  • Threw a no-hitter as a member of the Arizona Diamondbacks against the Tampa Bay Rays in a 1–0 win on June 25. It was the second no-hitter in Diamondbacks history and his first in his career.

Halladay walked Jay Bruce in the fifth inning as the only blemish on the record.

On September 29, Cox won his 90th game in a season for the 15th time in his career as a manager. This is tied for the second-most in Major League history with Joe McCarthy and is one behind the record held by John McGraw.
