A sports dynasty is generally defined as a team that dominates its sport or league for a number years. Manheim Township's girls' lacrosse team has done exactly that.With a convincing 19-14 win over Penn Manor in the Lancaster-Lebanon League Girls' Lacrosse championship Saturday at Warwick, the Blue Streaks hoisted their fourth straight L-L championship trophy."It's such a great accomplishment," said MT coach Mark Pinkerton, who won his third as the Streaks' boss. "I'm really proud of this one because of all the players we lost to graduation from last year's team. It shows that we have a great program."Molly Hendrick, a starter on all four championship teams, was thrilled to finish her L-L playing career with more hardware."This is great," said Hendrick, who scored a game-high eight goals. "I really wanted to win four for our program. I remember our first championship (a one-goal win over Hempfield in 2010) and how close that was. Each game since has been a little bit different."Emily McBride helped Township (16-4) jump out to an early 2-0 lead with an unassisted tally at 24:25 before finding Toni Yuko 27 seconds later.A pair of free position goals for Penn Manor (15-5), by Shannon Sloss and Mckenna Edwards that sandwiched another Yuko goal made it a one-goal game, 3-2, with 17:59 left in the opening half. Both teams traded goals to make it 4-3 before the Comets had a chance to even the game when Eryn McCoy misfired on an open net with under 15 minutes left in the first half.The Streaks took advantage and pumped in four straight goals to lead 8-3 with 9:48 left in the half, and eventually led 10-6 at the break."Township is a momentum team," PM coach Jenn Forney said. "I don't think that goal would have changed the outcome of the game, but Township got some momentum after that."Township opened the second half with a Hendrick-led 5-0 scoring run. The senior handed out assists to Yuko and Emily Mann and scored three times, including a behind-the-back shot to give the Streaks a 15-6 lead."I just thought it was the open shot," Hendrick joked.The Comets used a 3-0 run late in the second to get within six, 17-11, with 8:09 left and ended the game with three straight. Sloss scored three times for PM in the 6-2 run, Edwards twice and Jackie Hemler once."We improved from the last time we played them," Forney said. "So that's encouraging, but we obviously wanted to win this game."Township goalie Brianna Leaman stopped six shots to pick up the win.Pinkerton said his team will enjoy the win for a few days until the Streaks start getting prepared to defend their four straight District Three crowns."Back at it Monday because we'll be getting ready to go after the fifth district title," Pinkerton said. "It will different this time because we're a No. 7 seed."It could be tough."
