The Bishop Macdonell Celtics senior boys basketball team hit uncharted territory Saturday night.

The school’s junior team, meanwhile, returned to a familiar place.

The senior Celtics topped Centennial 69-59 in the District 10 basketball finals at the University of Guelph, giving the south-end school its first ever D10 senior boys cage championship.

The junior Celtics beat the Our Lady of Lourdes Crusaders 56-52 to win the junior title, the school’s fifth in the last six years.

Bishop Mac had four straight titles before the John F. Ross CVI Royals won it last season.

In the senior finals Saturday, Jesse Kendall scored 26 points for the Celtics while Mitchell Wood hit for 20 and Michael Ganson had a dozen.

For Centennial, Erik Sterne scored 25 and Tarang Sharma had 23.

For the junior Celtics, Lukas Wood had a game-high 28 points. Jack Morris had 10 and Brandon Whiteside scored nine. Craig Valeriote scored 13 points for Lourdes while Alex Hudecki had 12 and James Gerstenkorn had 11.

Saturday’s win was Bishop Macdonell’s first senior boys basketball title since the school’s opening in 2004 on Clair Road. The former Bishop Macdonell high school, located downtown, last won the championship in 1988.

The Celtics sweep gives the school three of the four D10 basketball championships this season. Bishop Mac won the senior girls title in November.
