Who was the oldest pitcher to throw a no-hitter?

On June 11, 1990, at the age of 43 years, four months, and 12 days, Nolan Ryan became the oldest pitcher to toss a no-hitter when he did it against the Oakland Athletics. He walked only two, struck out 14, and needed only two hours and forty-nine minutes to complete the masterpiece. Ryan became the first pitcher to throw a no-hitter for three different teams, and also the first pitcher to do it in three different decades. What made it all the more amazing was that it came in just his second start after coming off the DL.

The next season, at the age of 44 years, three months and one day, Ryan threw the seventh and final no-hitter in his career, a 3-0 victory over the Toronto Blue Jays.
