While there have been 296 no-hitters in Major League history, by the end of the 2016 season the big leagues had seen just 81 immmaculate innings. It's one of the rarest feats in baseball, and with good reason: It's really, really hard to strike out three consecutive professional hitters on three pitches each!
Of course, you wouldn't know that from looking at the last few months. During Wednesday night's 8-2 win over the Rays, Red Sox starter Rick Porcello needed just nine pitches to notch three K's in the fifth inning -- the eighth immaculate inning of 2017, setting a new single-season record.
