The last four undefeated Division 1 Massachusetts high school tennis teams battled Monday in Lexington

While Monday was primarily postseason preparation for all four teams, the games served as a barometer of where each contender stands and a confidence boost for the victors.

“This is a great win to take into the tournament,” said St. John’s Prep junior Jack Prokopis, who won his second singles match. “We lost to (Lexington) twice last year and they are the defending state champions. “That is very important to us.”

Here are conclusions from both parties:

▪ The Lexington women’s team is 59-1 since the start of the 2022 season, with its only loss coming to Boston Latin in the 2023 regular season.

While that loss dropped Lexington to the No. 4 seed, the Minutewomen still claimed a state title, a lesson coach Chance Fechtor’s team learned Monday.

“We’re still learning how the system works and gaining experience as a group,” Fechtor said. “Obviously we want to do a very good job, but last year we felt pressure before the game. This year there is no pressure because we will have confidence anyway.”

▪ Lexington posted dominant wins at all three singles spots, with wins by junior Kyra McCandless (6-1, 6-0) at No. 1, freshman Mia McCandless at No. 2 (6-2, 6-2) and junior Phoebe Jiang (6-1, 6-0) at No. 3. None of the three have lost this season.

The third single was a weak point for Lexington a year ago, but the additions of Mia McCandless, Kyra’s younger sister, as well as Jiang, who moved to Lexington this year from California, gave the Minutewomen a challenging trio to equalize.

Kyra McCandless was undefeated at second singles a year ago, and after Lexington lost junior star Diya Pachamuthu, she’s been equally dominant at first singles — her dominant win Monday against Boston Latin star Halina Nguyen is the latest example.

“It’s been great to move up to first singles as I always like to have more competitive matches,” Kyra McCandless said. “We’ve been working on integrating some new people as well, but I think as a team we have a lot of confidence.”

▪ On the men’s side, the Eagles received wins from sophomore John DeAngelis at first singles (6-1, 6-1), Prokopis at second singles (7-6, 6-3) and junior Luke Free in the third single (6-1, 3-6, 6-0) on the way to the sweep.

They also got wins from sophomore Boris Kouvminov and junior Luke Prokopis (6-4, 6-1) in the first doubles and from seniors Alex Melville and Mark McDuffee (7-5, 4-6, 6-4). in the second double.

The Eagles, who haven’t won the Division 1 title since 2002, cemented themselves as title favorites after Monday’s victory; Their undefeated record includes wins against six of the top 10 teams in the MIAA Power Rankings. While Lexington lost important talent from last year’s team, the win served as a reminder of St. John’s Prep’s growth.

“After the loss to Lexington last year in the semifinals, they said, ‘Coach, just one more point and we’ll be there,’” St. John’s Prep coach Mark Metropolis said. “And I said, ‘Well, you guys have to keep working hard and come back better.’ And if you look now, across our entire lineup, there is incredible focus and everyone has made great strides.”

St. John’s Prep’s success has been largely driven by its doubles teams, which have a combined record of 27-1 this season.

“For us, it definitely starts at the bottom,” Luke Prokopis said. “Some of the top teams have high-level college players, so it will be difficult there. But knowing that our last spot in the lineup is always strong gives us confidence and gives individual players the freedom to go out there knowing that it’s not all on their shoulders.”

The top of the Eagles lineup has also come together, led by DeAngelis and Jack Prokopis. After playing third singles as a freshman, DeAngelis moved up to first singles this season and has only lost twice.

“He’s becoming one of the best players in the state,” Metropolis said. “He’s put in his time this offseason and played a lot of tournaments to get to where he is now. “I have a lot of hope for him, especially in the tournament and also next year.”
