in reply to syntax error with map in list context

It's a known issue with Perl guessing wrong on the meaning of the initial {. See the Perldoc for map, in the paragraph beginning:

"{" starts both hash references and blocks, so "map { ..." could be either the start of map BLOCK LIST or map EXPR, LIST.

There are examples of how to avoid the problem in that doc, but my suggestion would be:

my %data = map +( "Player number $_" => [ map { 1 + int rand(10) } 1 .. 5 ] ), 1 .. 10;
