FAYETTEVILLE, Ark. -- Freshman right-hander Alex Lange limited Arkansas to one run in seven innings, and LSU pounded out 21 hits as the top-ranked Tigers defeated Arkansas, 16-3, at Baum Stadium.
LSU improved to 20-3 overall and 3-2 in the SEC, while Arkansas dropped to 11-10 and 1-4. Arkansas posted a 5-1 win in Game 1 of the series on Thursday night.
The teams conclude the series at 2 p.m. CT Saturday in a game that may be viewed on SEC Network +.
Freshman right-hander Jake Godfrey will start on the mound for LSU, while the Razorbacks will counter with junior right-hander Trey Killian.
Lange (5-0) on Friday allowed just one run on four hits - all singles - with two walks and six strikeouts, firing 99 pitches in the outing.
"Alex has amazing talent, but his best quality is the way he competes," said LSU coach Paul Mainieri. "He just went out tonight and competed with everything he had. When he has the mindset that he's just going to attack the hitters, he's pretty good and he's going to keep getting better."
The Tigers collected 21 hits in a game for the the third time this season. Centerfielder Andrew Stevenson had four hits and an RBI; second baseman Jared Foster had three hits, including a two-run homer and three RBI; rightfielder Mark Laird and catcher Kade Scivicque each had three hits and an RBI; and designated hitter Chris Sciambra had four RBI, including a bases-loaded triple.
"This is the fifth time I've come to Arkansas as LSU's coach," Mainieri said, "and this the the first time we've had an offensive game like this. Games like this are rare here, I can assure you, so the best thing we can do is put it to bed and get ready to play tomorrow."
Arkansas starter James Teague (0-1) was charged with the loss as he surrendered four runs on seven hits in three innings with two walks and no strikeouts.
LSU grabbed a 2-0 lead in the bottom of the first inning against Teague as Scivicque and third baseman Conner Hale lined RBI singles.
The Tigers extended the lead to 4-0 in the fourth when Foster produced a run-scoring single and Sciambra delivered an RBI groundout.
Arkansas scored its only run against Lange in the bottom of the fourth on a sacrifice fly by rightfielder Tyler Spoon.
LSU erupted for four runs in the fifth, as Sciambra highlighted the inning with a bases-loaded triple after leftfielder Jake Fraley had drawn a bases-loaded walk.
Foster's two-run homer in the seventh, his fourth dinger of the season, gave the Tigers a 10-1 advantage.
LSU added six runs in the ninth, sending 11 batters to the plate. The outburst was highlighted by run-scoring singles by Laird, Stevenson, third baseman Danny Zardon and catcher Michael Papierski.
