What would you use to replace a broken putter during a round of golf?

QUESTION:
I’ve been playing Tiger Woods 09. When a character makes a bad shot, they will sometimes throw a tantrum and break their club. This happens most often with a putter.

According to the USGA Rules of Golf, an intentionally damaged club cannot be replaced during a round.

My question: If you just broke your putter during a tournament, what club out of those remaining in your bag would you use to putt?

ANSWER:

Answer by gorilla
lob wedge played with the club laid wide open and ball forward in the stance. Strike ball just on the equator with the edge of the club. Gets good rotation like a putt and with a little practice, you can make putts. I actually practice with the club from time to time as it helps me to focus on staying down through the putt. If you move on the lob-putt, you can hit some pretty ugly stuff.
Have actually used this club in tourney play several times.
