Senior Ayden Lumsden has seen growth in the Riverside Brookfield High School boys lacrosse team over four varsity seasons. The Bulldogs’ 15-4 Senior Night victory over Nazareth Academy May 11 was another shining example.
“Our (defensive midfielders), offense, defense are playing cohesively. We’re playing as a team,” Lumsden said. “Through my four years here it’s been different. I think our drills have improved. Overall this is more of a lacrosse team. I think we’re a little bit more finesse, more actual lacrosse playing.”
Especially with more than a dozen seniors, the Bulldogs (7-7) still have unfinished business as they begin play in the Oak Forest Sectional.
Lumsden, Benjamin Buscio, Patrick Galloway, Peter Laube and Eddie Schook have been four-year team members. Add to that seniors Troy Alvarez, John Evans, Jr., Luke Ferguson, Andres Gasca, Warren Mason, Xavier Mrozik-DeJesus, Damian Nieves, Jacob Retana and Joey Zimmerman.

Lyons Township (13-3) is the sectional’s No. 2 seed to St. Ignatius and RBHS is No. 8. The Bulldogs played No. 9 Whitney Young in Tuesday’s quarterfinals for the seniors’ final home game.
In 2025, they recorded the program’s first postseason victory by beating Brother Rice 19-0. The seniors joke how first-year head coach Justin Headley with an extensive lacrosse background was an assistant coach with the Crusaders last season.
“I just feel these past four years these guys have truly become my brothers,” Schook said. “I’ve made life-long friends and it’s just been an awesome experience. We’ve had some awesome victories. It’s been so great to celebrate with these guys.”
Against Nazareth, RBHS scored the final six goals. Xavier-Mrozik earlier scored with a between-the-legs shot as the 2025 honorable mention all-stater has eclipsed 50 goals for the season. The Bulldogs also have won their last three and came though in a “barn burner,” as Schook called it, 9-8 at Hoffman Estates April 21.
“That was probably the best I’ve seen them compete the whole year. It was back and back and back and forth and they came out on top,” Headley said. “(Nazareth) was probably our most complete win. We’re playing fluid lacrosse right now. We’re getting hot at the right time.”
Division I Mercyhurst-recruit Xavier-Mrozik has been a key addition since transferring from Fenwick after his freshman year. Zimmerman has been with the Bulldogs the past two seasons after playing two at St. Ignatius.
“We have a really good group here and it’s going to be sad leaving everyone,” Zimmerman said. “It’s the best sport ever. You’re with a tone of guys getting physical, getting after it, super fun.”
In the Marist Sectional, the No. 8 RBHS girls (2-12) beat No. 9 Kenwood 24-6 Monday for their second win in three games. They play No. 1 St. Ignatius in Saturday’s quarterfinals.
The LTHS girls (5-12) are the No. 6 seed in the Maine South Sectional.
Baseball
Lyons Township remains in the thick of another wild West Suburban Conference Silver Division title race after beating 2-1 Downers Grove North in Western Springs Monday.
LTHS (21-9, 12-5 in Silver) and Downers North (19-11, 11-6) were scheduled to play in Tuesday’s conference finale for both teams. Hinsdale Central (21-10, 11-5) and Oak Park and River Forest (24-8, 11-5) finish out with Proviso West and York, respectively.
In the Upstate Eight Conference East Division, Riverside Brookfield (19-8, 12-5 in UEC East) will finish second to Glenbard East (17-10-1, 15-2) after suffering a 17-0 loss to UEC West leader South Elgin Thursday. They are scheduled to play the Rams Tuesday and finish with Larkin Wednesday, May 19. Glenbard East won the first meeting 12-10 May 5.
Senior first baseman Eli Costello (.359, 1 HR, 26 RBIs) has been among the improved Bulldogs from his 2025 numbers (.295, 0 HR, 22 RBIs).
“I think this year our team is doing better at hitting with people in scoring position and not striking out as much. I’ve been just playing more loose and having more fun,” said Costello, who achieved his first varsity home run in the first inning against Argo March 23. “It felt great to get the team going early and to get my first one out of the way.”
