Less number of fouls, initially pitched by pitcher (4)
I believe the answer is:
ewer
'pitcher' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ewer that I've seen before include "Oversized jug" , "Water-jar" , "Were (anag)" , "Jug with wide spout" , "Big jug" .)
