SOUTH DEERFIELD — It all came down to one match.

During Tuesday’s Class B semifinal of the Western Massachusetts tournament between the No. 2 Frontier girls tennis team and No. 3 St. Mary’s, both squads were deadlocked, 2-2, heading into second doubles, the final match of the afternoon.

Luckily for the Redhawks, Brooke Charest and Hailey Fernandez know a thing or two about pressure situations and pulled through yet again, winning the deciding match, 6-1, 6-3, against the Saints to send Frontier to the Class B final in an entertaining victory on its home court.

“They knew it was 2-2 at that point and it’s not an unusual position for them,” Redhawks head coach Andrew Varnon said. “Brooke and Hailey are both eighth-graders and they’re young and they’re joyous and they really enjoy playing, which is good to see. It’s infectious.”

Charest and Fernandez have been unstoppable between the lines for Frontier this season in second doubles, as evidenced by their undefeated record, which improved to 15-0 with their match-clinching win Tuesday.

“It was a very exciting match,” Varnon said. “The score line was in our favor, but I think there were good points and good play on both sides.”

The Redhawks’ first doubles tandem of Esther Ehle and Aylen Shaw were victorious by scores of 6-1, 6-2 and Kayla Fagan, their second singles, won 6-2, 6-3, which lined up with how Varnon’s young group—entire team is composed of eighth and ninth-graders--have approached every match this season.

“As I’ve told my girls, we try to win both doubles and scratch a point out of singles every match and we were able to do that today,” Varnon said. 

Thanushi Ratnatunge (first singles, 3-6, 3-6) and Ella Sibley (third singles, 2-6, 3-6) counted as Frontier’s two defeats in the semifinal. 

St. Mary’s won the first meeting between these two teams, 3-2, on April 29, which served as a preview for another closely-contested match on Tuesday.

“St. Mary’s is a really spirited, friendly team and we enjoy playing them,” Varnon said. “We lost to them earlier in the season, 2-3, but there were two three-setters in that match, so it was really close. I knew that this was a team that if we played well, we could beat, so we did.”

The Redhawks (14-5) now get the chance to knock off the reigning Class B champions on Wednesday in the championship match, when they’ll square off with top-seeded Belchertown. The Orioles improved their record to 17-2 in their 5-0 win against No. 4 Pope Francis in the other semifinal match.

No matter what happens in the final, Varnon is proud of what is team has accomplished throughout the season.

“We have already had a better season than I hoped for,” Varnon said. “I told the players at the beginning that it was reasonable for us to finish better than .500 and make the tournament. So for us to win in the first round of Western Mass. is just awesome.”
