Coast Guard led 26-25 at halftime, but saw Trinity outscore the Bears 38-17 in the second half. The Bears led 26-16 with 4:06 left in the first half, but saw the Bantams outscore them 47-17 the rest of the way.
Junior Gill Gerton led the Bears with 12 points and six rebounds while sophomore Johanna Moolenaar, who had just three career points in 14 games entering the night, finished with seven points for the Bears.
The Bantams improve to 5-1 while the Bears drop their fifth straight to dip to 2-5 on the season.
Trinity shot 38.2 percent in the win (21 of 55) while making 2 of 15 from 3-point range while Coast Guard shot 32.7 percent from the floor (17 of 52) and made one of 14 from behind the arc. The Bantams held a 39-26 edge on the glass in the win.
The Bears led 10-5 following a pair of free throws by freshman Laura Irish with 1:36 left before the Bantams ran off the final seven points of the quarter to lead 12-10.
Coast Guard used a 7-0 run to take its largest lead of the game 26-16 following a layup by Moolenaar with 4:06 left, but again it was the Bantams with a big run to end the quarter as Trinity scored the final nine points cutting the deficit to 26-25 at halftime.
Trinity was 8 for 26 from the floor (30.8 percent) in the first half while connecting on 2 of 11 from 3-point range while Bears shot 40 percent in the first half (10 of 25) missing all six from behind the arc.
It remained a one possession game for much of the third quarter as the Bears led 32-31 with 4:21 left before the Bantams once again used a late quarter run outscoring the Bears 13-2 to take a 44-34 lead after three quarter.
Junior Jill Bray made the Bears only 3-pointer of the game with 3:21 left to make the score 52-43, but as they had all night, the Bantams used a big run, this time scoring the final 11 points of the game.
Coast Guard is back in action on Wednesday night when the Bears host Clark in a NEWMAC game at 7:00.
