The numbers game in baseball isn’t all slide rules, spreadsheets and sabermetrics. There can be some fun stats that find their way into the numerical lexicon from time to time.
The Guillen Number is one such stat. Coined by Joe Sheehan at Baseball Prospectus, simply stated, it is the percent of runs scored via the home run. It’s named after White Sox manager Ozzie Guillen who, despite having a reputation for living by the small ball, actually fielded a lineup that was extremely home run reliant. (Although how great would it have been if the Guillen Number was named after erstwhile Royals outfielder, Jose Guillen, who was paid $36 million by Kansas City and rewarded them with a 94 OPS+ over two and a half years.
