Home-standing Central Lyon took advantage of a cold shooting performance by the Patriots to register a 56-33 win over H-BC.
H-BC, which made 29 percent of its field goals and free throws in the game, experienced an especially rough second half.
The Patriots were outscored 37-14 in the final 16 minutes of play, when the game was taken over by CL.
"We just went cold and turned the ball over too many times in the second half," said Patriot coach Tom Goehle. "Then we tried to play catch-up and started to foul them, and they made their free throws in the fourth quarter."
H-BC played well enough to earn a 12-10 edge in the first quarter before CL rallied to knot the score at 19 by halftime.
The Lions opened a 33-23 lead in the third quarter before outscoring the Patriots 23-10 in the fourth quarter to win by 23.
Shanna Tilstra netted a team-high eight points for the Patriots.
Becky Broesder charted five rebounds and four assists for the Patriots, while Jody Rentschler chipped in five rebounds.
