Francisco Liriano No-Hitter Through Seven. Who Was the Last Pitcher to Have 2 No-Hitters in the Same Year?

If Liriano can get through two more innings, he will have his second no-hitter this year. I know Halladay had a perfect game in the regular season and a no-hitter in the playoffs. Who's the last pitcher to have two no-hitters in the same regular season?
