Fourth seed Thomaz Bellucci ousted world No. 74 Jerzy Janowicz of Poland in the quarterfinal of the Kremlin Cup on Friday.
The Brazilian No. 1 converted his only break point in the first set to take it, and won the second on a tie break returning from 5-3 down to secure a 6-4, 7-6(3) win.
Bellucci advances to the semifinal on his first appearance in Moscow and will face Ivo Karlovic, ranked 130th, who dispatched French qualifier Edouard Roger-Vasselin earlier Friday.
This will be their third clash, with the Croatian veteran winning both previous in 2008.
The second semifinal will see second seed Andreas Seppi play Malek Jaziri of Tunisia.
