We shared a teammate (quiz)

The following pairs of players shared a common teammate; that is, a player
that played with both of them.  None of the middle links are obscure
players, but it may require a little head-scratching.  You can use the
Oracle at http://www.baseball-reference.com to find out the answers.
Warning:  correct answers may prompt me to make harder quizzes...

1.  Ken Boyer... ...Robb Nen

2.  Warren Spahn... ...Cory Snyder

3.  Roy Face...  ...Jimmy Key

4.  Tito Francona...  ...Walt Weiss

5.  Hank Sauer...  ...Robin Yount


Good luck!

ps - I was going to do a link between Manny Mota and Carlos Delgado, but it
turns out two players shared that pair.  Can you get them both?
