It is the Lancers' fourth loss in five games as they fall to 7-4 overall, 1-2 PacWest.
Dixie State, the defending conference champion, improves to 9-4, 4-1.
The top two shooting teams in the PacWest slugged it out in the first half, but a well-played first half was overshadowed by a sluggish second as the Lancers went ice cold, missing 18 of their first 22 shots through the first 14 minutes.
What was a one-point halftime lead vanished in a flash and eventually became a double-digit deficit.
The Lancers led 35-34 at halftime but were limited to just one field goal in the first seven minutes and trailed 43-37 with 13:21 left. They got within four a few times, but the Red Storm swelled the lead to 55-45 with 8:32 to play.
A rare Evans 3-point play with 5:26 got the Lancers within 59-51 but Dalton Groskreutz drilled a 3-pointer and Kimball Payne completed a 3-point play with 2:49 left to make it 67-51.
Dixie State shot 49 percent, including 52 percent in the second half, and had five in double figures. Gorskreutz led the Red Storm with 17 points.
Wong gave the Lancers a big lift in the first half and his fourth 3-pointer of the half gave the Lancers a 30-25 lead with 3:53 left, the largest lead for either team in the half. The lead changed hands eight times, and the Lancers led 35-34 at halftime despite shooting just 37.5 percent from the floor.
Aside from Wong's 6 for 9 night from the floor, the Lancers' other four starters--Anthony Cosentino, Ivan Patterson, Andrew Fisk and Evans--combined to go just 10 for 38 (26.3 percent) from the floor. Cosentino had his streak of eight straight games in double figures snapped.
