Stroking the table

I've noticed that in table tennis, a lot of the professional players wipe the top corner of the table every now and then.

I wouldn't have thought that they would use that bit of table very often.

Do you know why this is?

Hi Kai,

They are usually wiping the sweat off their hands.  They use that part of the table because the ball doesn’t bounce there very often.
