Right-hander Jared Bradford was scheduled to start Sunday's game for LSU; however, he had problems with a blister on his hand during pre-game warm-ups. Verdugo (6-2) was called into action, and he responded with a gem, limiting the Rebels to two runs on three hits in nine innings with two walks and two strikeouts.
Gibbs led LSU's 13-hit attack, as he was 3-for-5 at the plate with a homer and four RBI.
"I'm very proud of our players for rebounding from a couple of tough losses to win this game today," said LSU coach Paul Mainieri. "We were determined to produce more offense today, and we did against some talented Ole Miss pitching.
"Ryan Verdugo was just outstanding on the mound. He gave us a tremendous effort when he was pressed into duty at the last minute. Our guys battled all weekend, and today we got an important victory."
LSU seized a 1-0 lead in the top of the second inning against Ole Miss starter Cody Satterwhite when rightfielder Derek Helenihi singled, moved to third on first baseman Matt Clark's single and scored on an RBI single by shortstop DJ LeMahieu.
An RBI single by designated hitter Jared Mitchell in the top of the fourth extended the Tigers' lead to 2-0.
Ole Miss responded to narrow the gap to 2-1 in the bottom of the fourth when centerfielder Logan Power launched a solo homer, the first hit of the game allowed by Verdugo.
LSU second baseman Ryan Schimpf launched a homer off of Satterwhite to lead off the fifth inning, giving the Tigers a 3-1 advantage. The homers was Schimpf's second of the series and his seventh on the year.
Ole Miss reduced the deficit to 3-2 in the bottom of the frame when catcher Brett Basham lined an RBI single.
The Tigers stretched the lead to 4-2 in the sixth when Gibbs unloaded a solo homer, the first dinger of his career.
LSU added two more runs in the seventh when third baseman Michael Hollander and leftfielder Blake Dean hit consecutive one-out singles, and Gibbs drove them home with a two-out single against Ole Miss ace reliever Scott Bittle.
The Tigers added two runs in the eighth against Bittle, who surrendered four runs – three earned – on four hits with one walk and four strikeouts.
Satterwhite (3-2) was charged with the loss as he allowed four runs on nine hits in 5.1 innings with one walk and four strikeouts.
The Tigers return to action at 6:30 p.m. Tuesday when the Tigers play host to Nicholls State in Alex Box Stadium.
