Sullivan, who matched his career best with three RBIs in Saturday's win, began NU's offensive day with a two-run double in the bottom of the first, and has had six multi-RBI efforts in his last 12 games.
Anderson said that Sullivan provided a much-needed spark for the Huskers, who have now won 18 of 20 games at Hawks Field and are off to their best Big 12 start since the league's inception.
"It was Nick Sullivan day at the ballpark," Anderson said. "He had a great day. I realized I made a huge mistake yesterday. I said each day it's somebody different contributing, but that's two days in a row for Nick. I'm very happy for him. He's worked really hard at what he's doing to get himself going. We needed something like that today."
While Sullivan, who totaled three of the Huskers' five hits on the day, powered the offense, Nebraska received a solid performance from starter Aaron Pribanic, while three relievers combined for three innings of two-hit ball to preserve the win
Pribanic (4-1) allowed three runs over six innings while striking out six for his fourth win of the season before turning the game over to the bullpen. In the seventh, Mike Nesseth got NU out of a two-on, two-out jam before Dan Jennings fanned a pair in the ninth for his third save.
The Huskers got out of the gate quickly against Red Raider starter Bettis, taking advantage of a pair of walks to plate two early runs. With one on, Mitch Abeita drew a two-out walk to keep the inning alive before Sullivan ripped the next pitch into the gap in right center, clearing the bases and giving NU a 2-0 lead.
Texas Tech (16-15, 4-8 Big 12) used the long ball to get back in the game, tying the game at two after solo homers from Doug Thennis in the third and Jason Seefeld in the fourth.
The Red Raiders took a 3-2 lead in the top of the sixth, as Seefeld drew a one-out walk and scored from first on Jeremy Mayo's double into the corner in right.
The Huskers came right back in the bottom of the sixth, as a walk to Jake Opitz and an Abeita single put runners on first and second for Sullivan. The Husker left fielder sent the first pitch he saw over the fence for a three-run homer, putting the Huskers ahead to stay.
Nebraska returns to action Tuesday night, as they travel to Iowa for a matchup with the Hawkeyes. First pitch is set for 6 p.m. and the game will be carried on the Husker Sports Network and on Huskers.com. The game will be shown on the Big Ten Network and will not shown on HuskersNside.
