A good start of the tournament for two Americans.
Querrey
World no. 82 Sam Querrey is aiming at improving his rank to defeat Bogomolov in straight set. Sam will probably play Hewitt in the second round.
Sock
Jack had a great win against boom boom Karlovic that was as effective as usual on his service to fire just 8 aces and win only 27% of the points on his second serve. The match ended after only 55 minutes. Jack will play either Becker or Ramirez Hidalgo in the next match.
