"We've won four straight but we're not going to be satisfied with that," Nevada forward Luke Babbitt said. "We need to learn a lot of things, especially not playing down to the level of our competition."
Nevada (6-4) trailed until a steal followed by a three-point play by Joey Shaw to give the Wolf Pack a slim 9-8 advantage.
"Anytime you get a streak going, you're trying to build some confidence, that momentum so that's very important," Nevada coach David Carter said.
Tied at 17, Shaw drained a jumper in the lane in transition after a Dario Hunt steal to take the lead, 19-17. A driving layup by Armon Johnson gave the Wolf Pack a four-point lead that it would not give up.
With fewer than seven minutes left, Keith Olson made his debut for the Wolf Pack.
"It's a feeling I've been waiting for a long time," Olson said. "I didn't really know how it would feel like when I stepped out there. It was definitely a lot better than what I thought it would feel like. I've been waiting for this chance forever. I took advantage of it. I can't really tell you how it felt, it's just exciting."
Olson, who had sat out for a year and this semester due to NCAA transfer rules, had five points and four assists in 12 minutes.
"I thought he played really well, considering he sat out for a year," Carter said. "When he went on the floor, it didn't seem like he missed a beat I didn't think. I think his conditioning was the only thing that suffered a little bit. I think he played very well. He gave us a presence inside both on the offensive and defense end."
Nevada strung together five points, capped by shot by Hunt to take a 30-20 lead over Wagner with 3:40 left on the clock.
Wagner (1-9) scored the final five points of the game capped by a trey by Tyler Murray to trail by five heading into the break, 32-27.
The start of the second half was nearly déjà vu for Wagner, this time with Chris Martin sinking a three and trimming Nevada's lead to just two.
"It's just your mentality," Babbitt said. "Coming in, you've got to fight through it mental before the game, at halftime and all parts during the game. Obviously we played well at points, the key is playing well for forty minutes. It's all in our heads. We'll keep improving."
Hunt dropped one in off the glass to push the lead back to two scores. A 9-0 run capped by a layup and free throw by Babbitt gave Nevada an 11-point advantage 45-32 with 15:39 left in the second half.
Nevada outscored Wagner 18-5 over a five-minute span to take its biggest lead of the game, 63-45 with about seven minutes to play.
With a few key three-point baskets by the Seahawks, Wagner pulled with eight, 69-61 on a Martin layup. Ray Kraemer responded with a 3-pointer and London Giles assisted Olson on a layup with 46 seconds left on the clock for the 74-61 win.
"No disrespect to Wagner, we know we can play a different level," Carter said. Sometimes young men in the game have a tendency to kind of know that 'hey we may be a little better or I can get my shot anytime or we're going to win the game.' And that's very hard to try to tell them you've got to play at a certain level every night.
"It's very frustrating as a coach because you know your players can play at a different level and that's a frustrating thing."
Wagner's Martin led all scores with 21. Michael Orock added 15 for the Seahawks.
Babbitt had a team-high 17 for Nevada. Johnson added 12. Brandon Fields and Joey Shaw added 11 apiece in the win. Fields also had five assists.
Nevada gave up 16 turnovers to Wagner. Nevada struggled from three-point range continued Saturday, missing all eight of its first-half attempts. The Wolf Pack made 3-of-6 in the second, pulling it's percentage to 21.4. Nevada shot 53.7 from field goal range on the night.
"Tonight, we got really good looks," Shaw said. "We've just got to keep working on our technique and focusing on when we get our open looks because we're getting a lot of open looks. Especially tonight. They just weren't going down tonight."
Nevada out-rebounded Wagner 42-29 and held the Seahawks to a lowly 35 percent from the field and 37.5 percent from beyond the arc. Wagner was better on second chance points, outscoring the Pack 11-2 while Nevada was quicker on the floor with 24 fast break points to Wagner's five.
Nevada travels to Las Vegas for the second half of its play in the Las Vegas Classic. The Wolf Pack has yet to win on the road this season but will have two chances next week to change that statistic. The first of two games will be against BYU on Tuesday at 12 p.m. Nevada will play again Wednesday against Nebraska or Tulsa.
Nevada will be home again to take on Portland on Dec. 28 before starting WAC play.
