LAWRENCE, Kansas (Ticker) -- A senior and freshman helped Kansas survive its toughest test of the young season.
Senior Wayne Simien scored 20 points and grabbed 11 rebounds and freshman guard Russell Robinson scored four points in the last 38 seconds as No. 2 Kansas escaped with a 64-60 victory over South Carolina for its seventh straight home victory to start the season.
Playing with a sprained left thumb that was injured during the game, Simien retrieved an airball by J.R. Giddens and dunked with 2:38 left, giving Kansas a 57-55 lead.
After Kansas City native Antoine Tisby converted a three-point play for South Carolina, Simien jammed home Keith Langford's missed layup with just over a minute remaining for a 59-58 lead.
The Gamecocks then isolated Tisby against Simien in the low post, but Simien, battling foul trouble, forced an off-balance shot that badly missed. Robinson took over from there.
Robinson converted a layup with 38 seconds left, his only basket of the game. After Carlos Powell's layup, Robinson made two free throws with 13 seconds left for a 63-60 lead.
Brandon Wallace missed a 3-pointer with five seconds left, and Langford made 1-of-2 free throws for the final margin.
"That was one of the shots that we had drawn up in the huddle, but I don't think he got a good look at it," South Carolina coach Dave Odom said. "Wayne Simien, being a senior and a great All-American, took that shot away. Hopefully Brandon, in the next few years, will just learn to pump fake that shot and drive the ball.
"Since Simien had four fouls in this situation he wasn't going to touch Brandon. Instead we gave into the jump shot there. I wanted him to take the jump shot if he was wide open, but he was not."
Robinson finished with seven points and two steals in his second 20-minute stint of the season.
"When coach had me in, I knew he was confident in me," Robinson said. "I knew he wanted me to make something happen. Once I had an opening (down the lane) I went in to try to put a little pressure on the defense. They just let me go to the basket and I layed it in.
"It was tough late in the game. I went in 3-of-6 from the line (in the game) and couldn't knock two straight down. I felt I had to make it a two-possession game. I calmly went up to the line and went through my normal routine and knocked both of them down."
Simien shot 7-of-13 from the floor and 5-of-6 from the line. He added a Kansas season-high six offensive rebounds en route to his sixth double-double.
"Wayne gets less respect than any good player that I have coached," Self said. "They fouled him really hard and nothing was called. We'll get X-rays and hopefully nothing is broken. If it is, he'll be out for a long time. We'll certainly hope and pray that it isn't bad."
Giddens scored nine of his 13 points in the first half and Aaron Miles added six points and eight assists for Kansas (7-0), which shot 42 percent (20-of-48).
"We didn't play very well, but you have to give South Carolina a lot of credit," Kansas coach Bill Self said. "They were more athletic and quicker to balls than we were. They were very ready to play and excited to play as evidenced by their quick start. We were not a very focused team at all. We stepped up and made some plays late."
South Carolina scored the game's first 11 points and led until Christian Moody's layup snapped a 52-52 tie with just over five minutes remaining. The 11-point deficit was the biggest of the season for Kansas.
"The beginning of the second half really hurt us," Odom said. "I really wanted us to come out strong in the second half. We knew that Kansas was going to put the pedal to the metal. We never got a handle defensively and we were just trading baskets.
"We did not want to get into a game where we were trading baskets with Kansas because that's a game we knew we would eventually lose and we did."
Powell scored 13 points, Josh Gonner added 12 and Tarence Kinsey 11 for the Gamecocks (5-2), who were held to 39 percent (21-of-54) shooting.
