What do you guys think of this match? Haven't seen either one playing this week but took Karlovic 2-0, a bit risky but not a big bet. Last time Lu played against Ivo's kind of player was in Auckland versus Isner, it was tight but Isner had 10 break points while Lu had only one. Might be similar match today, Karlovic holding easily and Lu being under pressure at least in a few service games, tiebreak(s) likely to happen.
