Loop only iterating once inside function

I have the following function which should return all the tournaments and corresponding rounds inside an array.

When I call the function inside the body using a print_r I get only one tournament and round returned, however there are multiple tournaments and rounds. It is like the loop exits after only one iteration

function getTournaments(){
    global $db;
        $sql = "SELECT tournament, weekNum 
                FROM schedule
                GROUP BY tournament";
        $stmnt = $db->prepare($sql);
        $stmnt->execute();
        $tournaments = $stmnt->fetchAll();

        $data = array();
        foreach($tournaments as $tournament){
                $data = array('tournament' => $tournament['tournament'], 'round' => $tournament['weekNum']);

        }//foreach
        return $data;
}//function

print_r(getTournaments());

Database dump

Here you can see the corresponding mysql statement run on the db

My output / Problem

As you can see on image below I only get one tournament and round returned when doing print_r, why am I not getting all tournaments and rounds returned inside the function array? Am I missing something here?

You should have used $data as an array :) Use this 

 $data[] = array('tournament' => $tournament['tournament'], 'round' => $tournament['weekNum']);

instead of 

$data = array('tournament' => $tournament['tournament'], 'round' => $tournament['weekNum']);

you over write $data in the loop you want to create new arrays (multidimensional):

$data[] = array('tournament' => $tournament['tournament'], 'round' => $tournament['weekNum']);
