Congratulations OCA Swimmers!

Congratulations to all of our OCA swimmers on an outstanding performance at the 14-Under PNS Championships! Finishing 4th overall and scoring over 2,000 points for the first time in team history is an incredible achievement scoring 472 more points than last year. This marks one of the most successful championship meets OCA has ever had.

This group delivered across the board: breaking team records, qualifying for new championship-level meets, and posting countless personal best swims. From relay swimmers to individual event scorers, every single swimmer played a role in this success. Your commitment, effort, and team-first attitude made the difference.

A special shout-out to our standout performances:
• Caden Baker — Champion in both the 100 & 200 Breaststroke
• Hayes Feng — Winner of all three 13–14 Breaststroke events, setting new team records in the 50 & 200 Breast with a futures cut in the 200 breast
• Henry Linowski — 1st place in the 11–12 Boys 50 Backstroke
• Maya Aktas — Broke the 10-Under Girls team records in the 100 & 500 Freestyle
• Henry Liu — Set a new team record in the 50 Freestyle
• 11–12 Boys 400 Medley Relay — 1st place finish, with multiple other relays placing in the top three
