Michigan Medal Play Golf Championship at Detroit Golf Club

Formerly known as the Horton Smith Invitational, this 72-hole stroke play event, founded in 1964 by Bill Michaels, began as an 18-hole invitational to honor the long-time Detroit Golf Club Head Professional who had a rich playing career (he was the first Masters champion and the last person to defeat Bobby Jones in competition before Jones' retirement in 1930). However, in 2020, Smith's name was removed from the state's most prestigious event due to his staunch support of whites-only membership while serving as PGA president in the 1950s. This coincided with the PGA of America's removal of his name from their annual award given to a PGA member for outstanding contributions to professional education. In 2020, the PGA renamed it as the PGA Professional Development Award. The organization had a whites-only clause from 1934 through 1961.

The invitational is held each spring and has taken place at Detroit Golf Club every year since 1964, the year after Smith died.
