Bobby Petrino saved his toughest call for Arkansas' biggest game of the season. Petrino went for it on fourth-and-3 in the fourth quarter on Saturday and Ryan Mallett made the move pay off with a 39-yard touchdown pass to Joe Adams. The play paved the way for the No. 12 Razorbacks' 31-23 win over LSU (No. 5 BCS, No. 6 AP), and it kept alive Arkansas' chances for the school's first BCS bowl bid.
