world cup , ghana vs uruguay result. fair or not??

Tweet

yesterday, Ghana lost to Uruguay on penalties. but the big decision was at the very end of extra time when Lus suarez, the Uruguayan striker blatantly saved a shot that would have won the game for the Ghanaians, be it by using his hands. he was sent off but the resulting penalty kick was missed and the uruguayans went on to win on penalty kicks. my que is. was it fair for the Ghanaians to be denied a goal by such an unsportsmanlike fashion? should the ref have awarded the goal?
