Anyone else think it's stupid for Pettitte to pitch in the WBC?

From Anthony McCarron:

Andy Pettitte and Mark Teixeira, two Yankees who endured injury problems last season, are scheduled to play for Team USA in the World Baseball Classic in March, a source with knowledge of the roster confirmed Monday.

...

If a club does not want a player to participate because of injury, it can submit what’s called a “player objection notice” to the WBC’s disability review committee, which could rule on the objection. But with both Pettitte and Teixeira on track to be ready for spring training next month and both wanting to play, it’s not like the Yankees can prevent their participation.

I can understand letting Teixeira play. He's a notorious slow-starter and maybe a few competitive games prior to the season will do him some good. However, letting a 40-year-old Andy Pettitte, pitch in meaningless exhibition games masquerading as an important international competition is a joke.
