In his first bout of the evening, Abas faced 2002 World champion Rene Montero of Cuba at 55 kg/121 lbs. and earned an electrifying 4-3 come-from behind win to claim his pool.    Abas fell behind early, when Montero scored a first-period exposure for a 2-0 lead. Montero padded his lead to 3-0 on a takedown early in the second period. Abas began his comeback with a takedown at the 4:01 mark for a 3-1 score. He closed the gap to 3-2 with a takedown with just 30 seconds to go. With just 18 seconds left in the match, Abas turned Montero with a two-point gutwrench for the stunning 4-3 win.    Abas moved into the quarterfinals against Li Zhengyu of China, and earned a 6-1 victory. The first period was scoreless until the final few seconds, when Abas scored a takedown and a quick high gut wrench turn for three points and a 3-0 lead at the break. Just 24 seconds into the second period, Abas hit a three-point takedown with exposure to extend his lead to 6-0. Zhengyu was able to score a one-point reversal later in the match, but Abas shut down his attack to seal the 6-1 win.    Abas will face Chikara Tanabe of Japan in the semifinals on Saturday morning during the 9:30 a.m. session.

Sanderson quickly scored a double leg takedown taking Borchanko straight to his back for three points in the first five seconds. Borchanko scored a takedown to close the lead to 3-1, but a reversal, then another takedown, gave Sanderson a 6-1 lead at the break. In the second period, Sanderson went from an ankle pick to a double leg finish, then quickly turned Borchanko again for two more exposure points, stretching his lead to 9-1.    Sanderson then moved on into the quarterfinals, where he edged 2002 World bronze medalist Majid Khodaei of Iran, 6-5 in overtime at 6:17. It was exciting bout, in which Sanderson needed to come from behind late in the bout for the win.    Sanderson scored first on a low single leg attack, taking a 1-0 lead. In a scramble situation, the officials awarded two points to each wrestler when both were exposed, and the score was 3-2 in favor of Sanderson at the break. Early in the second period, Khodaei scored a takedown to tie it at 3-3, then took a 5-3 lead on a two-point tilt. Sanderson came back with two takedowns, including the final score with just 22 seconds left in the period, to tie the bout at 5-5. Just 17 seconds into overtime, Sanderson won the bout on a single leg takedown for the 6-5 win.    He will face 1999 World Champion and 2000 Olympic silver medalist Yoel Romero of Cuba in the semifinals on Saturday morning during the 9:30 a.m. session.
