It's been a long time since I've played against a quality lefty. I usually don't have problems with leftys, but 2 days ago I played one with a nasty backhand slice. The ball has a ton of underspin on it and stays low and has some sidespin and I can't seem to time it well. With a good righty slice I have no problem hitting passing shots off, but with this slice it's just weird to time and be even slightly aggressive on. Does anyone have trouble with this?
