    often heard this saying from some coaches - spin provides control...

    this maybe good to shovel down some students throat, but may not make sense to others.

    sure, topspin pulls the ball down, so that does give control.... but underspin floats the ball aerodynamically, how the hell does underspin provide control?

    the real explanation, is that when player uses a strong knifing motion, like Fed's slice, the centrifugal force pulls the arm/racket taut, and ensures accurate face angle thru impact, therefore he can make the ball fly 1/2 inch over the net without error..... and the underspin/side spin happens to be the by product of the knifing motion.

    Hitting with more spin increase the dwell time at contact - thus more control.

    Don't really get the point you are trying to make in the ast paragraph?

    it was a pointless attempt to clarify something - (which will probably end up confusing people lol)

    increase the dwell time - how? ball sinks into string bed then bounces out.

    a difference in the 'foot print' the ball makes on the string bed maybe, but I don't see how dwell is different.

    probably moot point either way as far as winning or losing is concerned.

    spin gives you more margin for error in the ball flight (more clearance and shorter drop) but less margin for error at the ball strike because the racket moves at an angle to the ball.

    baseball players talk about matching the plane of the pitch with the swing which means a flat swing. if you do that you can be a ittle late or early and still hit the ball square while with the topspin you only need to be an inch late and you frame or even miss it.

    with the modern "across" strokes this becomes even more pronounced since you also need to time it well laterally.

    here is an illustration (black arrow ball, red arrow racket path, green lines represent hitting zone)

    for that reason most clean ballstrikers like davydenko and agassi are relatively flat hitters (relatively of course) while the extreme spin players tend to shank a little more (see federer).

    however in the end a shank is not worse then a long miss due to too flat hitting so you need to find a happy medium between both.

    You are all missing the point. OP was not talking about control due to top spin, which we know is due to higher net clearance and getting the ball to land in.

    OP was asking about why underspin provides more control.

    Answer is what he himself said: there is more area of the strings to play with, and the arm can be more taut for greater precision. I would add that there is also a reduction is speed, which also provides control.

    Control has variety of meanings:

    - "hit the ball back" control
    - "hit a court spot" control
    - "against the wind" control
    - "passing shot" control
    - "racquet stabilization" control

    By definition, every time you hit the ball and consciously do something to it to get a desire result-- you are controlling the ball. Spin is one option you have for controlling the ball and makinging a choice about how you want the ball to behave. If you hit the ball with no spin at all, then gravity, direction and speed are the only factors you have to work with. With spin- topspin, underspin, sidespin (and combinations of the those) you do have more contol and more options.

    Keeping the ball low and making it skid is controlling the ball. Hitting hard with topspin- angled wide- is controlling the ball. Just holding out your racket and letting the ball bounce off- is not so effective.

    Imaging a serve with no spin at all- you either bloop it in or drive it hard with little margin for error. Adding various spins to the serve allows you to conrtol may things- height of bounce, direction of bounce- it allows you to use more angles, to hit harder, produce kicks and spins. In essence the same things can be said for groundstrokes, as well.
