The Titans lost by over 20 points on the road in the high altitudes of the Mile High City, losing to the University of Denver 79-57 on Saturday.
"It was really a tough game for us," Titans forward Yaphett King said. "We had a hard time adjusting to the altitude out there and we were fatiguing a lot faster."
The loss evens out Fullerton's record at 2-2.
The Titans were as cold as the Rocky Mountains, shooting a dismal 35 percent from the field.
Fullerton started off poorly, only making 11 out of 35 shots from the floor and earning just one point from the free throw line in the first half.
Denver dominated from the tip and led the Titans going into halftime 45-26.
The second half wasn't much better for the Titans.
Fullerton scored 31 points while giving up 39 points on 53 percent shooting to the Pioneers.
Sophomore Bobby Brown led the Titans in scoring with 17 points but was 7-for-23 from the field.
King was the only other Titan scoring in double figures with 14 points to go along with his six rebounds and four steals.
"We were just rushing a lot of our shots," CSUF guard Bobby Brown said.
The Pioneers were led by sophomore forward Antonio Porch who had game highs with 21 points and 13 rebounds.
Pioneers' guard Erik Benzel scored his 1000th career point and added 15 points including five out of eight shot from three-point range.
Denver improves its record to 3-2.
Titans scoring leader Jermaine Harper, who came into the game averaging 17 points a game, was held scoreless in 29 minutes of action. Harper missed all eight of his shot attempts including four from three-point range.
Starting center Derek Quinet scored four points and managed two rebounds, eventually fouling out after 29 minutes of game time.
Hardy Asprilla who came into the game leading the Big West Conference averaging 12 rebounds a game, grabbed only seven rebounds but did have a team high of five steals.
Forward Danny Lambert, in his first appearance of the year, played four minutes. Lambert didn't play prior to Saturday's night game, because he was recovering from a torn meniscus.
The Titans will play Denver again on Dec. 23 at home in the Titan Gym.
"They got one on us and we're just waiting to get them back when they come to our house," Brown said.
Fullerton will play its next game on the road against Eastern Washington on Saturday at 7:05 p.m. A win over the Eagles will push the Titans' record above .500 for the second time this season.
