A pitch with American running back on: for this? (5,4)
I believe the answer is:
super bowl
'for this?' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'a pitch with american running back' is the wordplay.
'a' becomes 'per' (eg 'one a day' means 'one per day').
'pitch' becomes 'bowl' (I am not sure about this - if you are sure you should believe this answer much more).
'with' says to put letters next to each other.
'american' becomes 'US' (United States).
'running back' says the letters should be written in reverse.
'us' backwards is 'su'.
'per'+'bowl'='perbowl'
'perbowl' put after 'su' is 'SUPER BOWL'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for super bowl that I've seen before include "NFL championship match" , "American sporting event" , "match across the pond" , "sporting occasion" , "US football final" .)
