Rain on the Clipboard

Medium — logic-grid deduction puzzle

A late shower washed away the volunteer's notes, so only the crowd's memory is left of how Edward, Lucy, Thomas and Charlotte served on the show court.

It was first-round day at the old grass-court event, and four singles matches were played on the show court, one after another. Edward, Lucy, Thomas and Charlotte all won. A club volunteer sat beside the court with a speed gun and a clipboard and wrote down two things about each winner: their fastest serve, in kilometres per hour, and how many aces they served. An ace is a serve the other player never even touches. Two of the winners hit a serve over 200, and the crowd roared each time the speed gun showed one. Two of them also reached ten aces or more, and the crowd cheered again for that. The sun was hot all afternoon, and each winner kept it off with something different on their head. Then a late shower soaked the clipboard where it lay on the umpire's chair, and the ink ran. Now the afternoon has to be put back together from what the crowd remembers.

Clues

1. Edward and Charlotte both hit a faster top serve than Lucy.
2. The fastest serve of the player in the visor was faster than the cap wearer's and slower than the bandana wearer's.
3. Thomas, the player whose fastest serve was 178 km/h and the player in the cap were three different people.
4. Edward's fastest serve was 201 or 214 km/h.
5. Either Charlotte wore the cap or Thomas wore the visor, but not both.
6. Neither Edward nor Lucy served as many aces as Thomas.
7. Whoever wore the visor served one of these two numbers of aces: 12 or 18.
8. Whoever wore the cap served fewer aces than whoever wore the headband.
