Perfect Game

 

[SamSniped]

Right-batting, left-handed pitchers?
Member: Jesse Orosco
Non-Member: SamSniped (I bat/pitch right)

 

[Arrow Gamer]

Cy Young winners (I have no idea if Randy Johnson win that)

Member: Brandon Webb
Nonmember: Cy Young

 

[choxorn]

Yes, he has. 5 times.

Arrow Gamer's guess is very close, just not quite specific enough.

Not all that surprising Johnson's the only member so far, as it's a very small set, but I'll give you another member as a hint:

Member: Randy Johnson, Pedro Martinez

Non-Member: Magic Johnson, John Tomas, NinjaCow64, Barry Sanders, Cal Ripken Jr., Jesus Christ, Cal Ripkin Jr. Curt Schilling, Choxorn, Alex Rodriguez, Kobe Bryant, Felix Hernandez, Patrick Corbin, Jesse Orosco, SamSniped, Cy Young, Brandon Webb

 

[Nuka-sama]

Those who won the Cy Young award at least 2 years in a row?

Member: Greg Maddux
Non Member: Chipper Jones

 

[choxorn]

Not in a row, but every member of this group has at least 2 Cy Young Wins.

Another Hint:

Member: Randy Johnson, Pedro Martinez, Roy Halladay

Non-Member: Magic Johnson, John Tomas, NinjaCow64, Barry Sanders, Cal Ripken Jr., Jesus Christ, Cal Ripkin Jr. Curt Schilling, Choxorn, Alex Rodriguez, Kobe Bryant, Felix Hernandez, Patrick Corbin, Jesse Orosco, SamSniped, Cy Young, Brandon Webb, Greg Maddux, Chipper Jones

 

[Arrow Gamer]

Won the Cy Young award non consecutively?

Member: Roger Clemens

Nonmember: Arrow Gamer

 

[choxorn]

No, but Clemens is another member.

Member: Randy Johnson, Pedro Martinez, Roy Halladay, Roger Clemens

Non-Member: Magic Johnson, John Tomas, NinjaCow64, Barry Sanders, Cal Ripken Jr., Jesus Christ, Cal Ripkin Jr. Curt Schilling, Choxorn, Alex Rodriguez, Kobe Bryant, Felix Hernandez, Patrick Corbin, Jesse Orosco, SamSniped, Cy Young, Brandon Webb, Greg Maddux, Chipper Jones, Arrow Gamer

 

[Optical]

Won the Cy Young award twice in a row?

 

[Arrow Gamer]

Already suggested:

Won the cy young twice with different teams.

 

[choxorn]

Neither is the set, but Arrow Gamer is very close, and once again has guessed a set that this set is a subset of, and it's close enough that I'll give it to him.

The set was pitchers who have won the award in both leagues. It's an extremely small set, which consists only of the 4 people already listed as members and Gaylord Perry.
