See bright star Mike ultimately dominate part of tennis match (4,4)
I believe the answer is:
love game
'tennis match' is the definition.
The definition suggests a singular noun which matches the answer.
'see bright star mike ultimately dominate' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'bright star' becomes 'vega' (I've seen this before).
'mike' becomes 'M' (phonetic alphabet: alpha, bravo, charlie etc.).
'ultimately' suggests the final letters.
The final letter of 'dominate' is 'e'.
'lo'+'vega'+'m'+'e'='LOVE GAME'
'part of' is the link.
Can you help me to learn more?
(Another definition for love game that I've seen is " (Tennis) play in which the loser gets no score".)
