Madesyn Ronquillio led the Huskers in the backstroke events during her fifth season, opening with a 100 backstroke win at South Dakota State. Ronquillio went on to gather four top-five finishes in one weekend, as Nebraska hosted duals on back-to-back days. In the 100 backstroke, she finished second against Iowa State (56.56) and third against Minnesota and South Dakota (56.81). In the 200 backstroke, Ronquillio finished fourth against the Cyclones (2:06.0) and second in the double-dual (2:03.84). She helped Nebraska to a win over Iowa, pitching in a 200 backstroke victory (2:03.34) and a runner-up finish in the 100 backstroke (56.04). At Kansas, she swam to a pair of second-place finishes, while claiming another 100 backstroke victory against Omaha (56.98).

Ronquillio made an impact at the mid-season Hawkeye Invite, clocking a 1:58.45 in the 200 backstroke to take second and a 54.97 in the 100 backstroke to finish third. At the Illinois dual, Ronquillio collected a 200 backstroke victory in 1:59.71, while finishing third in the 100 backstroke with a 55.96. At the final dual of the season, Ronquillio raced to two more top-five finishes at Rutgers. Ronquillio capped off her career at the Big Ten Championships, swimming a leg of the 400 medley relay and finishing 25th in the 200 backstroke (1:58.81).

2021-22 (Senior)
Ronquillio started her senior campaign with an individual victory in the 100 backstroke, along with a pair of relay wins (200 medley relay, 200 freestyle relay) in a team win over South Dakota State. She continued to be a leader in the pool for the Huskers by winning the 100 back and swimming the leadoff leg in Nebraska’s victorious 200 medley relay to open a dual win over Iowa (Oct. 23). Ronquillio capped a big day against the Hawkeyes with a third-place finish in the 100 butterfly to complete a sweep of the top three spots for the Huskers. Ronquillio provided the first win of the meet against a tough Minnesota crew in the 200 backstroke and went on to win the same event the very next day against Iowa State. In the 100 backstroke, she added a runner-up finish against Iowa State and a third-place finish against Minnesota to prove her backstroke dominance.

Continuing her winning ways, Ronquillio swam to two more backstroke victories in a dual against Kansas (100 back, 200 back). At the competitive Mizzou Invitational (Nov. 17-19), Ronquillio finished fifth in the 100 backstroke with a 55.18 and eighth in the 200 backstroke with a 2:01.19.

The transfer from Boise State who joined the Big Red after the Broncos eliminated their program on July 2, 2020, scored for the Huskers in both the 100 and 200 backstroke events at the 2021 Big Ten Championships in Minneapolis.
