BOULDER — Justin Nguyen realized the momentum was on his side and that all he had to do was stay the course in order to secure a big win on the tennis court.

By remaining steady until he finally reached the finish line, Nguyen not only dispatched his opponent, but also delivered a monumental win for Monarch as well.

Nguyen, the Coyotes’ No. 1 singles player, survived a three-set thriller against Boulder’s Galen Arney, breaking a tie between the teams and lifting Monarch to a 4-3 victory.

“I had the momentum after winning the (second set) and I was pretty pumped up,” Nguyen said. “Then I won a couple big points, and from there I sort of knew I’d be able to pull it out if I kept going.

“This is a huge step. When I was a freshman, we had a huge freshman team. Now we’re all seniors and we have a pretty strong team. I think this will be the strongest we’ll be for a while. We’ve never beaten Boulder and this is a huge win for us.”

After dropping the first set 6-4, Nguyen rallied in the second set and drew even with a 6-4 decision. Because the No. 1 singles match suffered a late start, and with the daylight rapidly dwindling, the third set was played as a 10-point tiebreaker. The final frame was tied at 6-6 before Nguyen reeled off four of the final five points to secure the victory.

Nguyen improved to 4-0, as did the Coyotes as a team.

“It’s a huge, huge win,” said fourth-year Monarch coach Mary Prassa. “Since I’ve been coaching, this is our best season.”

Prassa was forced to shuffle her lineup on Tuesday when senior Jack Shanahan, the team’s only returning state qualifier and Monarch’s usual No. 2 singles player, became unavailable due to a wrist injury. Nonetheless, Monarch received victories from No. 3 singles player Danny Wright in addition to its top two doubles teams.

Monarch’s top pairing of Jason Nguyen and Jason Ferry defeated Boulder’s Levi Chandler and Cutler Essen 6-1, 6-1, while the No. 2 team of Chad Brown and Derek Wright earned a 6-1, 6-1 win against the Panthers’ Connor Dawson and Cole Smith.

“It’s huge, especially since we were a little shorthanded today,” Prassa said. “It’s really tough not to have Jack, and the whole team feels that when he’s not playing. But it shows you what they can do. They still stayed positive and they still fought really hard.”

Boulder earned wins at the No. 3 and No. 4 doubles slots and also benefited from another strong showing by freshman Jackson Hawk at No. 2 singles. Hawk recorded a 6-2, 6-0 win against Diego Trujillo, who was playing his first varsity singles match for the Coyotes, to improve to 5-0 this season.

“Everyone is really big and really tall, so I’ve just been trying to get my serves in,” Hawk said. “Most of the kids have a pretty good serve and a forehand, but I’ve been able to get my way through.”
