Hewson, an 18-year-old England international, has made a dream start to her career at Clemson University in South Carolina.
She tied for first place in her first tournament with a six-under par score and days later took the honours at the Lady Paladin Invitational with a score of three-under for 54 holes.
She is only the second Clemson woman golfer to win consecutive tournaments.
“What a tremendous accomplishment to not only win once, but to win back to back tournaments,” said head coach JT Horton of his freshman golfer. “She has tremendous poise and maturity for a freshman. We are proud of her.”
Hewson had rounds of 67-73-73 in claiming the two-shot victory.
She finished ahead of Jess Meek and Michelle Butler of Missouri, and Hewson is now nine-under-par for her six rounds at Clemson.
Her five-under 67 in the first round of the tournament was just one shot off the Lady Paladin Tournament record and was the second best round in Clemson history.
