Shannon Garrity went 3-for-3 with an RBI, and Chelmsford pitcher Jackie Arndt struck out 10 batters, as the Lions on Friday defeated Tewksbury, 3-1, to win a share of the Merrimack Valley Conference Division 1 title.
In this wildest MVC softball pennant race in memory, Chelmsford and Methuen already own shares of the league title at 10-4. The winner of Sunday's Central Catholic at Dracut game will also grab a share.
Tewksbury fell to 9-5 in the league.
Garrity, a junior, raised her batting average to .620 on the season. Arndt, also a junior, allowed 1 run on 6 hits and 3 walks.
Chelmsford (14-5) scored its three runs in the first inning against Tewksbury ace Shannon McLaughlin, who also struck out 10 batters.
Senior Brooke Hardy had 2 hits for Tewksbury.
Billerica scored 5 runs in the top of the first inning, but Dracut reeled in the visitors, with Allison Ramirez and Madison Ryan each driving in three runs.
Ramirez had 2 hits, including a triple. Ryan also had 2 hits. Sam Durand had 3 hits, including a double, and 2 RBI.
Dracut (10-6) secured a state-tournament bid. The Middies can still win a share of the MVC Division 1 title by beating Central Catholic on Sunday.
Groton-Dunstable senior Alyssa Ash pitched a 3-hitter with 13 strikeouts, including her 300th career K, and also smacked a solo home run.
Groton-Dunstable improved to 9-10, and needs to defeat Tyngsboro on Sunday at home to qualify for the state tournament.
Ash had an RBI ground out in the first inning, hit a home run leading off the fourth, and later scored another run. Annika Liljegren had an RBI single for the Crusaders.
