Show post by slug sanitize_title

Except the title of the post is

echo sanitize_title(news_get_meta('gamers'));

I’m assuming news_get_meta is a function particular to a theme or plugin you have installed, so your query should be:

$query = new WP_Query( array(
    'post_type' => 'spa',
    'name'      => sanitize_title( news_get_meta('gamers') );
) );
