Yes it is three.
Good to see A Bog win, although I could not be here sadly.
I thought of adding a preview sort of thing.
Alex's opponent in the second round, 32 year old Marcelo Charpentier of Argentina has a current world ranking of 754, but has a protection at 226, hence being eligible to play here. He missed a full two years of tennis due to injuries!
He was once ranked as high as 114(in 1997) and going by the norm for Argentinians, is a clay specialist. His comeback has not gone particularly well, with only four wins in as many clay Challengers.
Clay is obviously Alex's least favourite surface, but his confidence is sky high at the moment and he gave a fine performance today. So Charpentier should not pose as too much of a problem for him.
