MANSFIELD — A Terrance Hubby tip-in of a Corinthian Ramsey drive to the basket with 15 seconds left gave Mansfield Summit only its third lead of the game, but the Jaguars were able to hang on for a 49-47 victory over Mansfield Lake Ridge in a District 15-4A game Tuesday night at Lake Ridge.The win, Summit’s second over Lake Ridge this season, put the Jaguars (16-9, 7-3 District 15-4A) in the driver’s seat for the second playoff seed out of the district. Lake Ridge (17-7, 6-4) fell a game behind in the race.“This is big for us because Lake Ridge is a very good basketball team, and to beat them twice in a season is quite an accomplishment,” Summit coach Jason Mutterer said afterward. “It’s big because it gives us the tiebreaker over them and puts us in a good position.”The game might have been different had either team taken advantage at the free-throw line.Through the first three quarters, the Jaguars and Eagles had made just 8 of 22 combined free throws. Things didn’t improve for Lake Ridge in the fourth quarter, as the Eagles went 4 of 9 when the game got tight.After leading scorer Jacob Van missed his third free throw of the final period, he fouled out on a charging call, canceling a basket that would’ve given Lake Ridge a four-point edge.Instead, Hubby tied the score with a dunk at the other end and got the game-winner moments later. His 16 points led Summit.Before fouling out, Van scored 18 points for Lake Ridge, hitting five 3-pointers as the Eagles built six-point leads in both the first and fourth quarters.
