Little League World Series tough trivia

1. Can anyone name the two players who played in the Little League WS, the College WS and the MLB World Series?

2. Who is the only player to be on a LLWS championship team and a MLB World Series champion?

3. Who is the only player to be on a LLWS championship team and the losing team in the MLB World Series?

4. What two teammates on a losing team in the LLWS championship were on a MLB World Series winning team?

Being a Mets fan, Michael Conforto is part of the answer to #1.

I was pretty sure the answer to #4 was Dwight Gooden and Gary Sheffield from Tampa but I was wrong. I think the correct answer is Sheffield and Derek Bell (I used Wikipedia). If anyone is curious, I discovered Baseball Almanac has a list of 13 players who were in both the LLBWS and the World Series, now 14 with Bellinger.

How about Boog Powell for question 2 ?

The correct answer to 4 is indeed Derek Bell and Gary Sheffield. The answer to 2 is not Boog Powell. His Lakeland FL team lost before the championship game.

I believe there are three correct answers to Question 1 - not just 2.
Jason Varitek, Ed Vosberg, and Michael Conforto
