Bryan Costabile threw two touchdown passes and Alvonte Thompson added a rushing score as No. 6 Mount St. Joseph High defeated Boys’ Latin School, 24-19, in a MIAA non-divisional football match on Lake Avenue Saturday.

The Gaels are 3-0 for the first time since 2010, but No. 3 wasn’t easy. After building a 21-6 halftime advantage, Mount St. Joseph needed a defensive stop to leave J. Duncan Smith Field victorious. The Irvington school has surpassed its 2013 win total.

“We have a tough schedule and BL is a good team,” said Gaels coach Blake Henry, whose is ranked No. 8 in the latest state media Top 25 poll after victories over state-ranked squads Bishop McNamara and Bullis School.  “I want the kids to believe a 20-point win or a one-point win is a great win.”

The Gaels fell behind Saturday, 3-0, after junior kicker and Wake Forest University commit Dom Maggio booted a 35-yard field goal for Boys’ Latin (1-1). Thompson, a senior running back, got Mount St. Joseph on the scoreboard with a four-yard touchdown run.

Costabile, who scored winning touchdown with 14 seconds left in regulation in Gaels’ thrilling decision over Bullis, threw scoring passes to Kyle Offerman and Jaden Blue, sending Mount St. Joseph into halftime with a comfortable margin.

The Lakers climbed back into contention in the third as junior quarterback Logan Wisknauskas threw a 65-yard scoring pass to sophomore Braden Atkinson. Jerel Archer’s touchdown run brought Boys’ Latin to within 21-19.

In the fourth, James Nelson booted a field goal, extending the Gaels’ advantage to 24-19. The Lakers reached Mount St. Joseph’s 35-yard line late in the fourth, but turned it over on downs.

“We played well. We have some tough kids this year,” said Lakers coach Ritchie Schell, whose team travels to Pennsylvania Saturday for a non-league matchup with Kiski School.

The Gaels will be on the road again, taking on Delaware’s Dover Friday evening. Dover, coached by former Ednondson coach Dante Jones, reached the Division I state semifinals last year.
