Arejola claimed both monthly awards in the 2018-19 fall season with the NEC's top scoring average in the month of October with 76.5 strokes per round. After announcing herself to the NEC with a pair of top-three performances last month, the freshman posted a pair of top-15 finishes, including one in the top-10 in October. She carded an NEC-low score at the Brown Bear Invite, tying for 13th place with a 6-over 150 that also helped the Knights to a third place showing out of 12 teams. Only a week later, Arejola used a red-hot second round of 73 to climb all the way back up to seventh on the leaderboard. That was a 10-stroke improvement from the previous round on the Saucon Valley's Grace Course in Bethlehem, PA.
