The Razorbacks' four freshmen - B.J. Young, Rashad Madden, Hunter Mickelson and DeVonta Abron - combined to score 53 points in a 86-44 win over Grambling State at Bud Walton Arena.
"When those guys came off the bench, I thought they took the tempo up a notch for us and really got us into our transition game," Arkansas coach Mike Anderson said.
"They got the most minutes of any of the guys out there, so to me, that's a reflection of their play. I thought they were at times pretty impressive."
The point totals were career-highs for all four players, while Mickelson recorded a career-high eight rebounds, had five assists, blocked three shots and recorded three of Arkansas' 16 steals.
"We played really well," Mickelson said. "All the freshmen on the team have been working real hard behind the scenes.
"Everybody is real happy. We had a great game tonight, passed the ball real well and were able to come out on top."
The Razorbacks used a tenacious full-court press defense against a Grambling team playing without senior guards Derron Hobbs and Raschard Boatner. Arkansas forced a season-high 27 turnovers, which it converted into 39 points.
Sparked by several of those turnovers and paced by its freshmen, Arkansas used a 20-0 run early in the first half to put the game out of reach. The Razorbacks led 41-25 at halftime.
Young scored eight points during the run and had 10 points at the intermission. His night also included a series of highlight reel dunks.
"In the open court, I've been around a lot of players, but he's one of the fastest guys in the open court," Anderson said. "He's real shifty and has a great first step, and he's got the length to finish."
Arkansas hit 44 percent of its shots in the win and outscored the Tigers 22-0 in transition.
Arkansas, which had been decidedly outrebounded in its previous two games against Houston and Utah Valley, won the battle of the boards 45-39 and had 26 second-chance points.
Grambling (0-5) hit only 27 percent of its shots in the contest and struggled to pass the ball against the Razorbacks' press. During one second half stretch, the Tigers failed to extend the ball past halfcourt on three consecutive possessions.
"Our guys just aren't that good; I knew that and (Arkansas) knew that," Grambling coach Bobby Washington said.
"They are so quick and that's something that we're not really used to. I actually thought we did a pretty decent job of handling the press for our level of play. I only have two scholarship players right now."
Arkansas is no stranger to low roster numbers, playing with only nine scholarship players - four below the NCAA limit. The Razorbacks had 11 players log time Saturday, all of whom made at least one field goal.
"We out-talented Grambling from the standpoint of the number of players we had," Anderson said. "That doesn't mean anything if you don't come out and perform. I thought we performed and hopefully we can build on it as we move on throughout our schedule."
Roman Higgins scored 16 points off the bench to lead Grambling, while PJ Roberson had a double-double with 12 points and 10 rebounds.
An estimated actual attendance of 5,500 watched the game at the 19,200-seat Bud Walton Arena - the sixth-lowest total since the school began keeping actual attendance figures.
Despite the low attendance, Arkansas announced Saturday it had surpassed the 5 million mark in attendance during the 19-year history of the venue.
