Halladay threw a perfect game against the Marlins in Miami on May 29, 2010. Later in the same year, on Oct 6., he threw a no-hitter against the Cincinnati Reds in the first game of the National League Division Series at Citizens Bank Park.
Halladay's no-hitter was just the second ever in the baseball playoffs, after Don Larsen threw a perfect game in the 1956 World Series for the New York Yankees.
"One of the most electric atmospheres I've ever been in," Halladay said of being roared on by the fans at Citizens Bank Park.
Here's a look back at our coverage of Halladay's perfect game and no-hitter, with links to our old stories and covers from the Inquirer and Daily News.
