It took 10 innings to decide the series on Sunday but the tiger outlasted the razorbacks with a 5-3 victory.  LSU closer Chris Cotton closed the door on Arkansas in front of a packed crowd at Baum Stadium. Sean McMullen had a sacrifice fly in the top of the 10th inning that turned out to be the winning run.  LSU improved to 34-3,13-2 SEC while Arkansas fell to 25-12,9-6 SEC.
