Following a first half mired by turnovers, the red-hot St. Mary’s boys basketball team woke up after the intermission Friday to earn a key victory in Southern Cascade League play on their home court during Senior Night.

Trailing 19-17 at halftime, the Trevhan Foster-led Crusaders took the lead in the third quarter and pulled away in the fourth for a 47-34 win over Illinois Valley for their sixth win in their last seven games.

The victory gave the Crusaders (11-11, 5-2 SCL) the tiebreaker edge over Illinois Valley in a battle of second- and third-place teams in the SCL. The edge in the standings gives St. Mary’s homecourt advantage in the league playoff game against the third-place team, which would be the Cougars.

“We played about as bad of a first half as we have all season,” said coach Kevin Dixon, whose Crusaders turned the ball over 13 times by halftime.

Foster provided 10 points, 14 rebounds and three blocks for the Crusaders, who were sparked by Sean Snyder’s 3-pointer to open the third quarter that helped put St. Mary’s in an early rhythm.

One of the Crusaders’ top defenders, Justin Silsbee, got aggressive attacking the basket and had perhaps his best performance of the season, according to Dixon, scoring seven of his nine points in the second half.

Gabe Mayer collected eight points and four assists for St. Mary’s, while Nathan Sternenberg went for five points and five rebounds.
