LEROY -- The opening round of the District 72 boys basketball tournament tipped off with Pine River emerging victorious 59-48 over the Mason County Central Spartans on Monday night at Pine River High School. The Bucks advance to the semifinal round where they will take on the Hesperia Panthers on Wednesday. The winner will move on to the District 72 title game on Friday Mason County Central is eliminated from the tournament and sees its season officially end. It took the Bucks a little more than one quarter to get into the flow of things and the result was a slow-paced offensive attack during the first eight minutes. After going into the second quarter trailing by a single-digit margin, Pine River finally took the momentum and used its home court to its advantage for the remainder of the half. Pine River had a 23-15 lead after the first half of basketball, fueled mostly by a barrage of second-quarter 3-pointers. Mason County Central saw an increase in productivity during the third quarter and its newfound accuracy to quickly erase its deficit. Once the final buzzer sounded off in the third quarter, Pine River still had the advantage but it was a much less convincing 35-30 margin. The Spartans played a more physical brand of basketball in the final quarter, but created perhaps too much contact and sent the Bucks into the bonus in the opening moments of the frame. Four points was the closest MCC came to tying the score late in the action. During the regular season, Pine River turned in a 6-14 overall record and went 4-12 in Highland Conference action to finish second from the bottom in the final league standings. MCC finished the regular season at 10-10, went 5-9 in West Michigan Conference competition, where the Spartans finished in fifth place. Tipoff is scheduled for 5:30 p.m. on Wednesday.
