The four players combined for 53 of the team's 61 points.
Michael Williams led the way for Fullerton (2-6) scoring 14 points and grabbing six rebounds. Senior forward Marquis Horne added nine points and five rebounds in the loss.
Junior guard Alex Harris returned from injury for the first time since Nov. 16 vs. Santa Clara.
The Titans and Cougars exchanged baskets to open up the second half, but a 6-0 run with 13:15 left pulled Fullerton within seven, 42-35. With 9:52 left, Sheldon Blackwell knocked down a corner trey to keep the Titans in the game, but back-to-back baskets by Stitt brought the Cougars lead back up to 12.
The Titans pulled within seven again after Williams converted a three-point play off a Blackwell steal with 4:57 left, but would only record one field goal in the final five minutes of play.
Cal State Fullerton trailed early on, 9-4, in the first half, but a Williams' corner three-pointer capped an 8-2 run by the Titans that gave Fullerton its first lead, 12-11, with 11:12 left to play in the first period.
After taking that lead, the Cougars' defense held CSF scoreless for over five minutes until another jumper from Williams ended the lapse at the 6:07 mark, but the bucket was Fullerton's only score during an 11-2 run from College of Charleston.
From the 11:12 mark of the first half, the College of Charleston ended the period on a 24-11 run, leading by as many as 13. In addition to his 11 first-half points on 4-of-5 shooting, Baru blocked four Titan shots in the first 20 minutes.
Fullerton will travel to Malibu, Calif., to take on the Pepperdine Waves on Wednesday, Dec. 4, while Charleston will return home to take on Coker on December 12.
