Nadal almost breaks, but that's a massive serve from Raonic and Nadal can't guide it back in. Subsequent shots go wide and quickly, it's game Raonic. There hasn't been a break of serve since the first set.
We're at 3-3 in the tiebreak and Raonic is running around - making Rafa do just that! He produces a brilliant shot and Nadal slides to make it - the next one, he misses. And it's Raonic with the mini-break.
