So much for an undefeated season.

The Duxbury boys’ tennis team seems to have all the ingredients for doing some damage in the Patriot League this year, as well as going deep into tournament play.

However, they took a step backwards last week in their season opener when they traveled to Hyannis to take on a loaded Cape Cod Academy, who pinned a 4-1 loss on the Dragons.

It was the first of a home-and-home series with the private school, with the second meeting taking place late in May when the Dragons will know what is in store.

In between, they’ll be able to feast on their league opponents and they did that on Wednesday in a 5-0 shutout of Silver Lake.

In the loss to CCA, Peter Muncey was the lone singles winner at No. 2 where he beat Tyler Kugler in three games, 6-2/2-6/6-2.

Brayden Minahan had a tough time handling junior Jon Zelman at No. 1 singles in a 2-6/4-6 loss, while Connor O’Keefe lost to Willy White at No. 3, 6-1/6-4.

The first doubles pairing of Alex Holopinen and William Kingsbury lost 6-1/6-3, but Peter Tenaglia and Stephan Day had a heart-breaking marathon match with John Heggarty and Oliver Rodgers at No. 2 doubles before losing in a three-set tie-breaker.

It was back to league play on Wednesday, and the Dragons felt right at home as they blanked the Lakers.

Minahan (6-0/6-1), Muncey (6-0/6-0) and Max Cote (6-1/6-2) barely broke a sweat in singles, while Tenaglia and Day had their way with Matt Kelly and Nick Vartyal, 6-1/6-2.

O’Keefe moved to doubles and teamed up with Holopinen for a 6-2/6-4 win over Nick Grovel and Nolan Lauttier.

“We’re playing well at singles, but are lacking consistent play at the doubles positions,” said Coach John Bunar.

The boys will travel to North Quincy on Wednesday afternoon before returning home on Thursday for an important Patriot League match with Hingham starting at 4 p.m.
