Dallas Braden threw the 19th perfect game in Major League history, defeating the Tampa Bay Rays 4-0 on May 9, 2010, which happened to be Mother's Day.

Armando Galarraga threw what would have been a third perfect game on June 2, 2010 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 him 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."
