Saito's watching too much TV

In a December interview with Grady Little made during the winter meetings (I just happened to stumble into it via Red Sox usenet group), an otherwise lackadaisical (sp?) Grady Little has this to say about our closer:

Q.  You had a new contract with [Takashi] Saito and are you happy to have him back to the Dodgers? 

GRADY LITTLE:  I would say so.  You know, he got an opportunity last year to come in.  He joined our club I think in May and I don't know the exact numbers but I do know the exact number of saves that he had -- he blew a save and that was one out of all of his opportunities.  He has good control.  He has good stuff and we're 
certainly glad he's back.

But I still haven't been able to figure out why I see the catcher go to the mound or my pitching coach go to the mound or I go to the mound and he puts his glove over his mouth so no one can read his lips.  I haven't really figured out why he does that yet.  *I think he's been watching too much TV*.  
Knowing how restrained (I previously used the wrong word "conceited" which Robert pointed out to me in the comments section) Grady can be (and is in many respects in this interview) I find this comment absolutely hilarious. I vaguely remember Saito having trouble speaking English last season - has he 
picked up any in the process so that he's protecting himself from being overheard? ;)
