Nothing surprises Arkansas coach John Pelphrey much anymore when it comes to the shooting of junior Rotnei Clarke.

Nothing surprises Arkansas coach John Pelphrey much anymore when it comes to the shooting of junior Rotnei Clarke.

Clarke scored 20 points, connecting on five 3-pointers, as the Razorbacks (1-0) opened the season with a 75-52 win over Grambling State on Thursday. All five of Clarke's field goals came from behind the arc, and he was the only Arkansas player to finish in double figures.

"When he makes five, that doesn't really surprise you," Pelphrey said. "That's a ridiculous night for a lot of people."

Last season, Clarke hit a school and Southeastern Conference record 13 3-pointers on his way a school-record 51 points in Arkansas' season-opening win over Alcorn State.

The Razorbacks went on to finish 14-18 a year ago and were picked to finish fourth in the SEC's Western Division this season.

Clarke started quickly on Thursday, hitting four 3-pointers on his way to 17 first-half points, before attempting only three shots in the second half as the Razorbacks struggled at times.

"It really doesn't matter individually where I'm at," Clarke said. "It's about this team and how well we're playing together and how well we're connecting. We're looking forward to it. We started off right and we got to keep going."

Clarke hit 46 percent of his 3-pointers last season, averaging 3.2 made from behind the arc per game on his way to averaging 15.1 points per game. He finished 5 of 10 in the win against Grambling.

"For him to go 5 for 10, we probably all take that for granted a little bit," Pelphrey said.

Arkansas led by as many as 22 points in the first half, taking a 42-20 lead when Clarke was fouled on a 3-point attempt and sank all three free throws. The Razorbacks forced the Tigers (0-3) into 11 of their 20 turnovers for the game in the first half, also holding Grambling to 34.9 percent shooting for the game.

Ten players scored for Arkansas, which only outscored Grambling 33-30 in the second half. The Razorbacks committed 16 turnovers but outrebounded the Tigers 34-25.

"Second half, I didn't think our attitude was very good in terms of being on edge and as alert and as intense as it was to start the game," Pelphrey said. "I thought we kind of thought we might be able to have an easy way of it in the second half, and unfortunately that attitude for this basketball team, you can't have that."

While Clarke was the lone player to finish in double figures, six Razorbacks finished with seven points. Delvon Johnson was one of the six, adding five blocks, and sophomore Glenn Bryant was another — including a pair of first-half steals and one-handed dunks.

"That's what coach (Pelphrey) tells me to do, to just bring energy and fly around," Bryant said. "I try and play the passing lanes as best as I can."

Grambling played without leading scorer Brandon Wilson, who sat out with nagging injuries. The Tigers were led by Justin Patton's 13 points and PJ Roberson added 12.
