On September 11, 1886, catcher Cornelius McGillicuddy, better known as Connie Mack, made his major league debut with the Washington Nationals (a.k.a. Senators). The Nationals defeated Philadelphia, 4-3, at Capitol Park in Washington.
Connie Mack went on to become the longest-serving manager in Major League Baseball history. He holds records for wins (3,731), losses (3,948), and games managed (7,755).
We have to get his name into the dictionary, something to denote longevity, mackified?
Mackified would be good. Playing off his real name would be fun, too: McGillicuddified. Say that five times fast.
