random new post

Ok, a question about the loop.

I have my category “news”, with 10 posts.
I want the loop to find the latest 3, and display only 1 of them (at random)

I guess i could do something like this…

$query = WP_Query('category_name=news&orderby=date&posts_per_page=3');
$rand = rand(1, 3);
$count = 1;
while($query->have_posts()):
	if($rand != $count){
		$count++;
		continue;
	}
	// Display post here
endwhile;

…but its not pretty.

Any sugestions, can i do this just with the right loop arguments?
