It was business as usual for the boys’ swim team, as it cruised to the Patriot League title by more than 100 points over Hingham and Scituate.

After narrowly missing a victory last year, the Dragons left no doubt that they were the 2009 champions, amassing 358 points in a victory that featured Hunter Chiasson winning two individual titles and contributing to wins in two relays.

Duxbury took a commanding lead in the first event, as Chiasson teamed with Cam Crowell, Jon Ng and Bernardo Neves to dust Hingham and Scituate by a full 10 seconds in the 200-yard medley relay, putting 32 points on the board.

Next up was the 200-yard freestyle where Art Su was able to break out of the pack to place fourth (2:01.80), only a second out of first. Drew Husted took sixth, Ben White was eighth and Ben Potash finished ninth. Even with four swimmers in the top 10, Duxbury’s lead was only three points.

Chiasson was determined to take control and give his team some breathing room, as he stepped to the blocks for the 200-yard IM next to Hingham’s Colin Mulachy. The two swimmers raced stroke for stroke to the wall in what looked like a tie. However, the scoreboard showed Chiasson won by 2/100 of a second in a time of 2:06.72. Even better, Lucas Wojciekowski touched third and Ben Zelvis was sixth, giving Duxbury a 30-point lead.

Next up was the 50-yard freestyle with 29 sprinters ready to hit the water. Neves was in the last heat where all swimmers had seed times under 25 seconds. He flashed through the water but was just touched out by Tommy Wong of Quincy/North Quincy, settling for second in 23.38. Husted was seventh, Drew Cooper was 10th in a personal best, and Andrew Gilmore was 20th.

As Neves and Chiasson rested, Wojciekowski, Ng, Cam Crowell and Andrew Sommer had some work to do in the 100-yard butterfly. All four swimmers stepped up, taking second, fourth, sixth, and seventh to add 40 points to the scoreboard.

Neves now had a second chance to better Wong in the 100-yard freestyle, as he sat through six heats to get his chance. The Brazilian barracuda wasted no time in taking a small lead after the first 50 yards and inched ahead to take the win in a season-low 50.86, only one second off the Duxbury High School record.  Teammate Barry Su took third (55.19) and Cooper was 13th.

The distance swimmers were on the blocks for the 500-yard freestyle, and once again Duxbury had more depth than the field, with four out of 14 wearing Dragon green.  Crowell was the top finisher (5:23.92), just missing second by 9/100 of a second. Ng was seventh, White took eighth and Potash finished 11th.

Duxbury had a commanding lead after nine events, but didn’t let up. Husted, Art Su, Ng and Barry Su sprinted their way to a 1:40.17 second-place finish in the 200-yard freestyle relay, right behind Scituate/Cohasset. While Hingham had been an early challenge, now it looked like Scituate/Cohasset was going to make waves.

Once again the senior co-captain took the blocks in his signature event; the 100-yard backstroke. Mulachy was in the next lane once again, so Chiasson knew he needed to swim up. The race was very close with the two swimmers even again for the first 50, but Chiasson dug in and came up with a one-second win (55.52), while Art Su was fourth and Jason Lijewski took sixth.

For the first time all day Duxbury hit the daily double, as the one-two punch of Barry Su and senior co-captain Sommer topped the podium with Zelvis finishing seventh and Keelan Murphy ending up 16th.

In the one-meter diving competition freshman Ian White put on a terrific performance, impressing the judges and placing second (125.00).

Despite having the championship in hand, Duxbury’s Chiasson, Su, Crowell and Neves were tested by Hingham, having to work hard for their first-place one-second victory in the relays.

“This was a true team effort,” said Coach Jay Craft. “Every swimmer contributed and our depth in every event helped us win the meet.”

On Saturday Chiasson, Neves, Art and Barry Su, Crowell, Ng, Lucas, Wojciekowski   and Husted traveled to MIT for the South/Central Massachusetts Sectionals.
