White Sox catcher Billy Sullivan secured a patent on the first chest protector. It contained a wind pad with compressed air. It was the forerunner of the modern catcher’s chest protector. Sullivan was the White Sox catcher from 1901 through 1914.
The U.S. Cellular Company and the White Sox signed an agreement selling the naming rights to Comiskey Park. The deal was worth $68 million over 23 years. The money received by the club contained the stipulation that it could only be used on renovations and upgrades for the stadium — not, say, for signing free agents. As a result of said renovations, U.S. Cellular Field became one of the finest-looking stadiums in baseball.
The Guaranteed Rate company would then secure naming rights in November 2016.
