Ivo Karlovic Reaches Semi's of Houston

Ivo Karlovic (CRO) (#174) had to qualify in Houston just to get to the main draw, but he reaches the semifinals, only to lose to Ryan Sweeting.  This should improve his ranking a bit, after also reaching the quarters of Doha and Indian Wells.  This was his path to the semi's -

SF - Ryan Sweeting (USA) (#93) 67(3) 36
QF - John Isner (USA) (29) 76(2) 67(2) 76(9)
2R - Igor Kunitsyn (RUS) (#89) 64 61
