NETANYA, Israel — Stony Brook swimmer Michal Liberman triumphantly returned to the Israeli National Championships during the past week, winning both the 100- and 50-meter butterfly events. And that was not even the most momentous occurrence during the competition.

On the final day of the meet at the Wingate Institute in the Mediterranean resort city of Netanya in central Israel, boyfriend Aaron Greenberg proposed to Liberman. She accepted, and the couple now is engaged.

"He proposed between the prelims and finals session on the last day," Liberman said. "So when I returned to the pool to swim the 50 fly, I was so happy and excited, it helped me swim fast and claim first place."

Liberman had joined Stony Brook swimming this academic year as a graduate student with a final year of eligibility in large part because of Greenberg.

Greenberg, a former Yale swimmer, knew Stony Brook head coach Kerry Smith from her time as an assistant coach with the Ivy League school.

With the Seawolves, Liberman produced program and ECAC Winter Championships meet records in December with a time of 54.89 in the 100-yard butterfly.

Liberman had excelled competing in her native Israel as a teenager, but had not qualified in recent years as her times slowed. In fact, she had not competed at the Israeli Short Course Meters nationals in six years.

Her return after the lengthy absence proved remarkable.

Liberman posted times of 1:00.09 in the 100-meter butterfly and 27.49 in the 50-meter butterfly to win those events.

About her only blemish came in the 50-meter backstroke, her signature event. Liberman was disqualified because of an early reaction time.

"I was terribly upset about it," she said. "The 50 back is my strongest event, and I had very high expectations. I know I could have won. Yet it was an important lesson for me. I put too much stress on myself and lost focus."

Additionally, Liberman was pleased with a fourth-place finish in the 100-meter backstroke — "my weakest event." She produced a near-personal-best time of 1:03:02.

Liberman also swam four relay races, taking third in the 200 free relay, second in the 200 medley relay while swimming the fly, first in the 200 free mix relay, and first in the 200 medley mix relay — setting a national record in that final event, during which she swam the backstroke.

"It was awesome, because my boyfriend was on my team swimming the breaststroke, and we made a new national record together," Liberman said.

Liberman returned to collegiate swimming this academic year after suffering a torn ACL in her left knee just before the start of the 2018-19 season as a senior at Eastern Michigan University.

The comeback from the serious knee injury made the Israeli nationals success even more gratifying.

Stony Brook's season resumes Jan. 11 at Florida Gulf Coast.

"I had a very good meet," Liberman said. "I proved that I am back from my time away being injured. I am even more excited now to carry on and finish the season even stronger at the conference championship. Many athletes and coaches from home were surprised by how well I was swimming and complimented me for my hard work."
