Why is Danny written & pronounced ダニー and not ダニ?


In Japanese, using Katakana, why is the name Danny written and pronounced ダニー.
Why not just ダニ? I'm not sure why the `i` is being extended when this doesn't
really happen in english.




Words brought to Japan from English speakers and which end in 'y' are usually
pronounced with extended 'i' sound.
