UPDATED Feb. 4: The members of the Arlington Boys & Girls Club (ABGC) Dolphin swim team turned in exciting season, shattering many long-held records.

Last Dec 11, Arlington High School senior Conor Sweeney crushed the 18 & Under 100-yard breaststroke record, which had been held for 14 years.

Sweeney finished with a time of 1:10:34, beating the previous record set by Robert St. Laurence in 2007 by more than one second.  Sweeney has been a member of the Dolphins since 2011, and his record breaking-streak didn't stop there. 

A month later, on Jan. 12, on Dolphin Senior Night, Sweeney broke his own 100-yard breaststroke record with a finish of 1:10:29.

Minutes later, Sweeney played a key role in breaking another record. The 18-&-under 200-yard medley-relay team of Cian Chambers, Sweeney, Robert Hackley and Sylvie Racicot finished with a time of 1:57:20, beating the previous record of 1:57:90 set in 2014.

Each teammate swam 50 yards of the following strokes: backstroke for Chambers, breaststroke for Sweeney, butterfly for Hackley and free style for Racicot.

No strangers to record setting, in 2020 Chambers and Racicot were teammates as half of the record-setting relay team for the 14-&-under medley relay.

The Dolphins swim for ABGC as well as their high school teams.  Sweeney, Chambers and Racicot swim for Arlington High School, while Hackley swims for Malden Catholic High School.

All four teens learned how to swim at the ABGC and are longtime club members.

In addition, Racicot broke through a gender barrier, as there had not previously been any female record holders in the 15-to-18 age group. Racicot, a junior, looks forward to further challenges. 

The Dolphins' season ends Feb. 10 with an in-house ribbon meet, the final opportunity for swimmers to break records for the 2021-22 season.
