The Rockville Municipal Swim Center hosted the 57th annual Montgomery County Swim League Individual All-Stars Sunday.
In the second event of the morning, Phoebe Bacon, who competes for Tallyho in Potomac, won the girls 12-under 100-meter individual medley (1 minutes, 9.04 seconds). She beat the old league record of 1:09.45, set five years earlier by Lauren James.
Bacon returned two hours later to establish another league mark in the 11-12 girls 50 butterfly (30.20). Bacon, 11, beat the previous mark set 14 years earlier by Laura Eull (Country Glen).
Less than 20 minutes later another league record was established as Giulia Baroldi (Potomac Glen) won the 9-10 girls 50 freestyle (29.58) over Jillian Berger (29.93, Little Falls).
Midway through the meet, Eli Fouts (Manchester Farm) earned a spot in the record books when he prevailed in the 13-14 boys’ 50 backstroke (27.11). Fouts would also set the league standard in the 13-14 boys’ 50 breaststroke (30.79).
Emily Wang, who swims for Upper County in Gaithersburg, won the 13-14 girls 50 back (30.18) and 50 fly (29.27).
But perhaps the most impressive performance of the day was delivered by Carsten Vissering (Old Georgetown) who won the 15-18 boys 100 breaststroke (1:00.74).
In her final meet with the MCSL, Anna Kolanowski, a 2013 Sherwood High graduate and rising sophomore at the University of Georgia who competes for Bethesda, won the 15-18 girls’ 50 butterfly (28.63).
“It was kind of bittersweet,” Kolanowski said. “I’ve been competing in this league since I was 5. Over the years it’s been a lot of fun. I’ve met a lot of good friends and had some really good competition. I was glad to end it with a win in the 50 fly.”
