Call more than one function in match arm in Rust

I currently have a match statement in the form of 

match ball.side {
    Side::Left => x(), 
    Side::Right => y(), 
}

But what I would need is something along the lines of 

match ball.side {
    Side::Left => x(),a(), 
    Side::Right => y(), b(), 
}

And of course this does not compile, but how could I make this kind of sequence work? I know I could also just work with an if-statement but I am curious how this can exactly be solved with match.

A sequence of statements in a block:

match ball.side {
    Side::Left => {
        x();
        a();
    }
    Side::Right => {
        y();
        b();
    }
}

Note that the right side of a match arm must be an expression, and that blocks are expressions (which can produce a value) in Rust.
