Berrer is unbelievable indoors! Part of me wonders how he's so bad outdoors though.
Exposure to the elements...sun, heat, humidity, wind. Also generally slower surfaces, which doesn't suit his game and exposes his lack of physical fitness.
Great week for Berrer...wouldn't have expected a SF (and possibly a final), and I had actually forgotten about how good he was earlier this year as he has been so quiet of late.
