Earlier in the week, Pargo had 18 points and five assists at No. 15 Georgia, but his 10 of 16 shooting against the Gators, including hitting seven of eight three-pointers, earned him player of the week honors from both SI and the Southeastern Conference.
Over one stretch against Florida, he scored 15 of UA's 17 points, and in the second half with the Razorbacks trailing 59-52, he scored six straight to cut the deficit to one.
Pargo, who is fourth in the SEC in scoring (17.2 ppg), ninth in field goal percentage (.467), fourth in three-point percentage (.406) and third with 3.32 three-point goals per game, made a three from the top of the key to tie the game at 81-81 with 26 seconds remaining to force the overtime.
After Florida tied the game with 16 seconds to go, Pargo held the ball at midcourt, ran the clock down and drove down the right side of the lane before pulling up and hitting the game-winner from 14 feet with 2.7 seconds left.
The preseason All-SEC selection averaged 26.5 points, 4.0 assists and 2.0 rebounds for the week while shooting 51.5 percent from the floor (17-33), including 60 percent from three-point range (9-15).
The 35-point game is the third 30-point outing of the season for Pargo. He is the first Hog to record three 30-point games in the same season since Todd Day in 1992 and the 35 points are the most for an Arkansas player since Al Dillard had 39 against Delaware State in 1994.
His nine threes for the week give him 136 for his career, just two away from tying Dillard for fifth on Arkansas' all-time list.
Pargo, who is also averaging 2.2 rebounds and 3.1 assists per game, has to the top two scoring games in the SEC this year with Saturday's outing and the 32-point performance against Tennessee-Chattanooga on Dec. 20. He also had 30 points at Memphis on Jan. 2.
Pargo was named SEC player of the week earlier this season after averaging 26.5 points, 4.0 assists and 2.0 rebounds against Tennessee-Chattanooga and Oklahoma State.
