BUDAPEST, Hungary (October 26) -- Olympic champion Davor STEFANEK (SRB) looks primed for another shot at world gold.

The 33-year-old Serb needed just 19 seconds to earn a fall over Fredrik BJERREHUUS (DEN) in the quarterfinals of the World Championships at 67kg on Friday. He had two technical fall victories prior to the quarterfinals and did not surrender a point. 

Stefanek, a 2014 world champion, now faces Gevorg SAHAKYAN (POL), who also earned a fall in the quarterfinals. 

Kazakhstan advanced two wrestlers to the semifinals. Both stunned Olympic medalists in Friday's opening session. 

Meiirzhan SHERMAKHANBET (KAZ) picked up two technical falls and a fall to reach the semifinals at 67kg. The fall came in his second match over 2016 Olympic champion Ismael BORRERO MOLINA (CUB). The Cuban star jumped out to a 5-0 lead before Shermakhanbet stormed back to take the lead and eventually earn the fall. 

In the quarterfinals, he faced Mohammadreza GERAEI (IRI). Shermakhanbet used a four-point throw, which he followed up with a gut wrench, to take a 6-0 lead. He closed out the technical fall a short time later. Shermakhanbet's opponent in the semifinals will be two-time world bronze medalist Artem SURKOV (RUS).

Surkov, a European champion, topped Kamran MAMMADOV (AZE) 5-1 in the quarterfinals. The 25-year-old Russian trailed 1-0 at the break but scored with two gut wrenches in the final period after getting a passivity point. Many expected Surkov to face two-time world champion Hansu RYU (KOR), but he fell early to Denys DEMYANKOV (UKR). 

Aidos SULTANGALI (KAZ) stunned 2016 Olympic silver medalist Shinobu OTA (JPN) 7-5 in the round of 16 at 60kg. In the quarterfinals, Sultangali cruised to a 9-1 technical fall over Kaly SULAIMANOV (KGZ). He will now meet Sergey EMELIN (RUS), who blanked Se Ung RI (PRK) 7-0. 

Kristian FRIS (SRB), a 2007 world bronze medalist, earned his spot in the semifinals at 60kg by getting a fall over Luis Alberto ORTA SANCHEZ (CUB). Fris led 3-1 in the second period before throwing Sanchez to his back for the fall. In the semifinals he will face Victor CIOBANU (MDA).

Ciobanu edged Sailike WALIHAN (CHN) 6-6 on criteria in the quarterfinals. Walihan held a 5-2 lead in the second period before Ciobanu used a body lock for four points to take the lead. He held on for the victory.

Reigning world champion Metehan BASAR (TUR) edged returning world bronze medalist Roberti KOBLIASHVILI (GEO) 1-1 on criteria in the quarterfinals at 87kg. It sets up a semifinal meeting with Bekkhan OZDOEV (RUS). 

Ozdoev went up 6-0 early against Rustam ASSAKALOV (UZB) after a takedown and two turns. Assakalov would get back in the match but come up short.

Olympic silver medalist Zhan BELENIUK (UKR) trailed 2-0 in the second period of his quarterfinal match before throwing 2017 world bronze medalist Hossein Ahmad NOURI (IRI) for four points to take the lead. He held on for the 4-2 victory. He now faces Islam ABBASOV (AZE) in the semifinals. 

Like Beleniuk, Abbasov trailed after the opening period of his quarterfinal match against before grabbing the lead after a passivity and gut wrench, which was enough to take the 4-1 victory over returning world silver medalist Radzik KULIYEU (BLR) and earn a spot in the semifinals.

The semifinals are scheduled to begin at 5 p.m. local time.
