The sophomore had to have had ice water in his veins Tuesday night, hitting what would have been two go-ahead baskets in the closing seconds of regulation before hitting the final go-ahead shot in overtime of Arkansas' 66-62 win over Missouri State in Bud Walton Arena.
His 3-pointer with 18.4 seconds left and pair of free throws with 1.7 seconds remaining in the extra frame were the final daggers in a game that featured seven ties and five lead changes.
Clarke scored Arkansas' last 12 points of the game.
"It was as clutch as I've seen him down the stretch," Arkansas coach John Pelphrey said. "He hit game-winners tonight and then he made a game-winning play with his defense when he made that rebound because those two free throws ice the game."
Clarke, Arkansas' leading scorer, had his best game since coming back from a knee injury that forced him to miss a game last Wednesday. In his return game Saturday, he scored nine points off the bench.
"He hit some big shots," Missouri State coach Cuonzo Martin said. "He's a guy that takes them and makes them. He's a talented player with a big-time stroke on him."
Clarke had just seven points before a 3-pointer gave Arkansas a 57-54 lead with 1:39 left in regulation. Clarke had lost the ball just moments before but made a heads-up play by knocking the ball away on the way back down the court, coming away with it, head-faking a defender and sinking the basket.
"The guy stepped around and stole it and I was frustrated so I thought I was just going to try and make a play," said Clarke, who also added four rebounds, two assists and a blocked shot to his line. "I knocked the ball loose from him. If I had missed that 3, I probably would have been even more frustrating, but luckily it went down. It felt good to get back what I just turned over.
"That was my main focus – not to get frustrated. Of course, I was a little bit, but I tried to keep my mind positive and have faith that if I was going to keep shooting, I would hit those shots at the end. Glory to God I did."
After Missouri State drained a 3-pointer to tie the game and the two teams swapped a pair of empty possessions, it appeared Clarke had given Arkansas the lead for good on a floater with 4.7 seconds left to extend the lead to 59-57. But a breakdown on the defensive end gave Caleb Patterson a wide-open lay-up as time expired to send the game into overtime.
Clarke said he felt the Razorbacks had the game in-hand before the lapse at the buzzer.
"All the momentum was on our side," Clarke said. "It didn't happen like that, but we showed a lot of toughness in the overtime and overcame some adversity…It was really big for us."
Clarke finished the night 6 of 12 from the floor after the poor start. Pelphrey said the strong finish will help in upcoming games against Baylor, UAB and Texas before Southeastern Conference play begins.
"It was good for him to keep playing because it's not always easy," Pelphrey said. "He's just got to keep going and keep going because there are a lot of good teams, a lot of good players, a lot of good coaches and the one thing they're going to try to do is not let him shoot."
