Tennis prayer

Dear God in heaven (or wherever you may be)
Please ease the pain that's in my knee
My shoulder, heel and elbow too
Just one more set, please get me through

Please let my balls return with pace
Please let me serve at least one ace
Don't let my smashes hit the net
(I haven't got one over yet)

Please help my volley and my slice
(A bit more topspin would be nice)
And when it seems I cannot cope
Please bless the balls I hit and hope

I thank you for this in advance
Please God if you get the chance
Bless me not him, I need it more
I've never beaten him before
