Cy Young Debut Game August 6, 1890

Cy Young established numerous pitching records, some of which have stood for a century. Young compiled 511 wins and was elected to the Baseball Hall of Fame in 1937. One year after Young's death, the Cy Young Awards created to honor the previous season's best pitcher.

In addition to wins, Young still holds the major league records for most career innings pitched,  most career games started (815), and most complete games (749).  He debuted on August 6, 1890 for the Cleveland Spiders.  All the newspapers I have looked did not have complete box scores (I guess they were not that important in 1890), but I did find this in my collection.
