This is just the second time in Major League history that there have been at least four no-hitters through May 7 in a season -- along with 1917, when there were five through that calendar date. The last no-hitter before Miley’s was John Means’ -- on May 5. It’s the shortest span between no-hitters across the Majors since 1990, when there were two no-hitters on the same day, on June 29 (Fernando Valenzuela and Dave Stewart).
