The junior guard, who played in China earlier this year, led Jeff Lebo's team in the first of three games vs. Mexican League pro teams as the Tigers took a 103-76 win.
Senior forward Quan Prowell scored 18 points, sophomore guard/forward Lucas Hargrove scored 15, senior guard Frank Tolbert added a dozen points and junior forward Korvotney Barber chipped in with 11 for the Tigers.
Not all of the news was good for the Tigers. Sophomore guard Dwayne Reed injured a foot and is not expected to play in the two remaining games. Another guard, senior Archie Miaway, is currently academically ineligible to play and was left back in Auburn.
The Tigers took control of the game with a 16-0 run to take a 42-28 lead with 7:45 left in the second quarter. By halftime the Tigers enjoyed a 61-36 lead.
"Defensively, in the second quarter, we were pretty good," Lebo said. "We only gave up eight points in that quarter. We fouled a little bit too much and put them on the foul line.
"For the most part, we were unselfish and moved the basketball. We made the extra pass, and that was encouraging to see."
The home team cut the gap to 78-60 after three quarters, but Barrett got hot down the stretch scoring 14 consecutive points and 18 of AU's final 21 points.
"My teammates were getting me open, and I was able to make the shots," Barrett said. "After the second one went in, the hoop looked like a real big sombrero."
The Tigers will play a rematch with the Pioneros at 7:30 p.m. on Friday.
