Casey Patrick Kelly (born October 4, 1989) is an American professional baseball pitcher in the San Francisco Giants organization.
 He was a first-round draft choice, 30th overall, in the 2008 Major League Baseball Draft by the Boston Red Sox.

On December 4, 1990, the Padres traded second baseman Roberto Alomar and outfielder Joe Carter to the Toronto Blue Jays in exchange for first baseman Fred McGriff and shortstop Tony Fernández.
 Blue Jays GM Pat Gillick and Padres GM Joe McIlvaine originally talked about just trading Joe Carter for Fred McGriff.
 The Padres were losing Jack Clark and needed a new first baseman.
 The Blue Jays had John Olerud ready to take over at first base but were losing outfielder George Bell.
 Gillick decided to up the ante by trying to get Roberto Alomar.
 Gillick figured that with Garry Templeton in the twilight of his career, Fernández would be an adequate replacement.
 Alomar feuded with Padres manager Greg Riddoch and the thinking was that Bip Roberts and Joey Cora could platoon at second base.
 Alomar and Carter would go on to help the Toronto Blue Jays win the 1992 World Series and 1993 World Series.

"Who's on First?"
 is a comedy routine made famous by Abbott and Costello.
 The premise of the sketch is that Abbott is identifying the players on a baseball team for Costello, but their names and nicknames can be interpreted as non-responsive answers to Costello's questions.
 For example, the first baseman is named "Who"; thus, the utterance "Who's on first" is ambiguous between the question ("Which person is the first baseman?")
 and the answer ("The name of the first baseman is 'Who).
