So listening to this, it just occurred to me...Arrieta was the only no-hitter in the MLB this year. The last time there was 1 or less no-hitters during a season was 2006, when only Anibal Sanchez had one. Interestingly, from 2004-2006 there were only 2 no hitters. Sanchez's in 2006 and Randy Johnson's perfect game in 2004.
