2001–2003 Wolfe began competing as Jarmila Gajdošová on the
ITF Women's Circuit just days after her 14th birthday in 2001, and that year entered three
ITF tournaments, winning two matches and losing three. In 2002, she again entered only three tournaments, but this time won four matches and lost three. Early in 2003, still aged 15, she stepped up her schedule, and that February she reached the semifinal of a $25k tournament at Redbridge, defeating
Séverine Beltrame,
Sandra Klösel, and
Roberta Vinci before losing to
Olga Barabanschikova. She won the next tournament she entered, her third of the year and only the ninth of her career. It was the $10k event at Rabat in March; and in the semifinal she defeated
Ekaterina Bychkova. On the strength of this result, she found herself wildcarded into qualifying for her first WTA Tour event, a clay-court tournament at Budapest in April, and justified the wildcard by defeating all three of her opponents in the qualifying draw, including
Melinda Czink, in straight sets, then
Virginie Razzano in the second round of the main draw, before losing 4–6, 3–6 to
Alicia Molik. On her 16th birthday she entered qualifying for a $50k event on grass at Gifu, Japan. Again, she qualified defeating
