Brydan is a good grass player and his ranking is false - don't forget he was a top junior....
As were tons of others.
But, yes, if his injuries are behind him, he certainly should be a fair bit higher than 400-ish and would be nice to see him in the UK for the summer season
Final: (1) Brydan Klein & Scott Puodziunas (AUS) CR 437 (265+172) lost to Jeremy Beale & Thomas Fancutt (AUS/AUS) UNR (0 [but a CH of 224 in Nov 2018]+436)
4-6 7-6(6) 10-3
