ANNVILLE, Pa.  -- Junior Lindsey Treanor allowed only four hits as Gettysburg knocked off No. 13 Lebanon Valley 5-0 in the nightcap and ended the Dutchmen’s perfect season in a non-conference softball doubleheader Tuesday night.

Lebanon Valley (18-1) tied a school record with its 18th consecutive win in the opener, holding Gettysburg (14-7) to just two hits. The only Bullets to reach base were sophomore Steph Zengel with a double in the first and junior Emily Hall with a single in the fifth.

The Dutchmen’s big inning was the third when 11 batters came to the plate. A two-run double by Sammie Bost capped the seven-run frame and set the final score.

Lebanon Valley failed to solve Treanor in game two. The Dutchmen had several opportunities to get on the scoreboard, putting runners in scoring position in the first, second, third, and sixth innings. But in each instance, the Gettysburg hurler worked out of the jam and the defense backed her up. All but three outs came via ground balls to the infield, with Treanor sealing the victory with three come-backers to the mound in the seventh.

Gettysburg hit the scoreboard in the third inning as senior Maggie Maguire drew a bases loaded walk. Sophomore Meghan Hisgen posted a two-run double in the fifth to extend the lead to 3-0.

Junior Melissa Tighe rapped a triple to plate another run in the sixth and she came in to score on a single by Zengel later in the fame.

Gettysburg’s win was its first against a ranked team since beating No. 5 Messiah 11-0 during the 2010 campaign.

Treanor picked up her third shutout and improved to 8-3 on the season. Over her past three outings, the junior has allowed just two earned runs and 16 hits over 20 innings.

Tighe finished 3-for-5 with a run and an RBI, while Zengel, Hall, and freshman Jamie Abell each went 2-for-4. Freshman Sam Misurell came up with two hits and a run after entering as a pinch-hitter in the sixth.
