The learning curve has grown exponentially steeper for Erin Blanchfield.

The onetime Eddie Bravo Invitational winner will square off with former Ultimate Fighting Championship women’s strawweight titleholder Jessica Andrade in the UFC Fight Night 219 headliner on Saturday at the UFC Apex in Las Vegas. Blanchfield enters the cage on the strength of a seven-fight winning streak. She last fought at UFC 281, where she disposed of Molly McCann with a kimura in the second round of their Nov. 12 pairing. A short-notice replacement for Taila Santos, Andrade has won three fights in a row. The Parana Vale Tudo cornerstone last competed on Jan. 21, when she routed Lauren Murphy in a woefully one-sided three-round unanimous decision at UFC 283.

As Blanchfield and Andrade make final preparations in advance of their forthcoming battle at 125 pounds, a look at some of the numbers that have accompanied them to this point:

23: Years of age for Blanchfield, who was born on May 4, 1999 in Elmwood Park, New Jersey.

3: Blanchfield victories by submission, accounting for 30% of her career total (10). Her methods of choice: one kimura, one guillotine choke and one keylock. Blanchfield owns two other victories by knockout or technical knockout (20%) and five more by decision (50%).

120: Significant strikes landed by Blanchfield in her three-round unanimous decision over Sarah Alpar at UFC Fight Night 192 on Sept. 18, 2021. It established a personal high-water mark for the Brazilian jiu-jitsu brown belt that stands to this day.

5: Consecutive calendar years in which Blanchfield has fought as a mixed martial artist. She went 3-0 in 2018, 1-1 in 2019, 2-0 in 2020, 2-0 in 2021 and 2-0 in 2022.

.688: Cumulative winning percentage between the four women—McCann, Alpar, J.J. Aldrich and Miranda Maverick—Blanchfield has beaten as a member of the UFC roster. They boast a combined record of 44-20.

31: Years of age for Andrade, who was born on Sept. 25, 1991 in Umuarama, Brazil.

9: Andrade wins by knockout or technical knockout, accounting for 38% of her career total (24). Her list of UFC victims: Cynthia Calvillo, Katlyn Chookagian, Rose Namajunas, Karolina Kowalkiewicz and Jessica Penne. Andrade holds eight other wins by submission (33%) and seven more by decision (29%).

74: Seconds needed for Andrade to put away Juliana Silva with a guillotine choke at Ring of Fire 4 on Aug. 28, 2012. More than a decade later, it remains the fastest finish of her career.

42: Rounds completed by Andrade across her 33 professional appearances. She has gone the distance on 10 different occasions and carries a 7-3 record in those bouts.

144: Combined victories between the nine women—Valentina Shevchenko, Rose Namajunas, Weili Zhang, Joanna Jedrzejczyk, Raquel Pennington, Marion Reneau, Liz Carmouche, Jennifer Maia and Kinberly Tanaka Novaes—who have defeated Andrade. They sport a .725 cumulative winning percentage at 144-54-2.
