6a. Beat a doctor in the final (7) ?A???S?
2d. main departure? (3)
17a. Sunny reflections (9) ?O?N?E?M? (Had thought of MOONBEAMS, but that's not really sunny is it??)
19a. Pull two out of shape (3)
16d. Not the best man (5) ???E? 2nd letter is middle letter of 19a.
I've got this crossword in front of me (knew there was something I meant to do!). All I can get to fit in 17a is, as you say, moonbeams so I'll go with that. All I can think of for 16d is loser but can't say I'm too happy with it. Hopefully someone else might have a better idea. Regards, Judy
