Pot odds and tournament theory

[whangarei]

Here is a specific example from this year's WSOP HORSE event. 3 players see 4th in Razz w/ respective chances of winning:

Matusow 48%
Tomko 34%
Pescatori 18%

Pescatori last to act on 4th, 20K to call, pot size is 145K. So it is correct to call according to pot odds if he is at least a 14% favorite (20/145). So, I assume the correct decision in a cash game is to call. But, can the correct decision change in a tournament based on stack sizes, blinds, etc?
