i did a search on "blowing on handle" but didn't get any so i was wondering if anyone knows why professionals, especially koreans, blow on their handles before receiving a serve? I see it a lot when professionals play and is it supposed to dry your handle? lol I don't think a little blow will affect the grip that much...
Maybe the grip spray/lube they used on their handles are still wet, that's probably why they would blow on the handles to dry it faster.
