Dear Uncle,
I would like to invite you to a cricket match on (date) from (time) to (time) at (place). I would love for you to come and visit me. It would be a great time to (say why you want him to come). You can (what he will do while at the cricket match or talk about something interesting about the cricket match to persuade him). I really hope you can make it!
Best wishes,
(your name)
