In our PE lesson we have been learning the technique of relaying  using a baton, making sure our head is held up  and arm out ready to receive the baton from the runner, we also needed good eye-hand coordination.
As the receiver we needed to keep our hand out ready to get a firm hold of the baton and make the pass over smooth so that we didn't drop the baton. 
The person handing over the baton needed to make sure that they had their arm outstretched and that they kept a good vision of the receiver to make the passover fast and smooth.
