Are No-Hitters On the Rise? No. Just the % of CGs.
Last night, Jered Weaver threw the 274th no-hitter in baseball history — or so the stories say. There have been two no-hitters so far this year, and ten so far in this young decade. Half of them came in 2010, the year whose no-hit frequency led some to dub it “The Year of the Pitcher.”
And, indeed, the five regular-season no-hitters thrown in 2010 (along with a sixth, by Roy Halladay, in the playoffs) mark it as one of the no-hittiest years in history. The five regular season no-nos tie it for third place, with 1962, 1968, 1973, and 1991, and the six overall tie it for second place with 1969. (Of course, many will remember that there almost was — and should have been — a seventh.) But the most of all were thrown in 1990: eight overall. The frequency of no-hitters per year hasn’t increased, except with respect to the historically anomalous 2000’s.
