There have been 276 no-hitters in major league history now. 21 of those have been perfect games. This is the 10th combined no-hitter. The record for most no-hitters in a single season is 7- it happened twice in 1990 and 1991. This baseball season isn’t close to being half over so they are on pace to break that record but these things are unpredictable. There may not be another one the rest of the way-who knows?
