2018: Breakthrough and Top 50

Collins started the year with a spirited run to the third of the qualifying rounds at the Australian Open, being outclassed by Denisa Allertová, who ultimately reached the fourth round, 6-0, 6-1 in just 45 minutes there. Nonetheless, she continued to ride on her momentum and took advantage of her wildcard at the WTA 125K tournament at Newport Beach, upsetting the odds and stormed to claim the title which then saw her rise to a career-high ranking of 120.^[4]

Another impressive run at yet another WTA 125k tournament, this time in Indian Wells, saw her reach the quarterfinals and thus earn her a wildcard at the BNP Paribas Open, a Premier Mandatory tournament also takes place in Indian Wells.

Although her run ended in the fourth-round to former World No. 6 Carla Suárez Navarro, Collins made her long-awaited Top 100 debut with her impressive form, jumping from no. 117 to 93.^[6]

Getting through the qualifying rounds at the Miami Open, Collins shocked world number 37 Irina-Camelia Begu 6-1, 6-1 before upsetting two-time Grand Slam semifinalist CoCo Vandeweghe in three sets. Incredible victories over Donna Vekić and Monica Puig followed, before the American earned the biggest victory of her career against her idol, former World No. 1 and seven-time Grand Slam champion Venus Williams, who was the eighth-ranked player coming into their encounter.^[7] Due to this success she became the first qualifier in history to reach the semifinals at the Miami Open.^[8] She then faced sixth seeded Jeļena Ostapenko and lost in straight sets despite having a set point in the first, rising to a then career high of 53.
