I went to a Red Sox game with my (adopted) work group this evening. In addition to beating Atlanta 9-4, Brock Holt hit a cycle - hitting a single, double, triple, and home run in a single game.
The Cycle is a very rare event; it has occurred 306 times as of today. This is about as rare as a no-hitter (288 times), and equates to about 2.5 cycles in a 160 game season with 30 teams.
