SUDBURY — Westford Academy’s perfect season is alive and well.

James McDermott raced home with the winning run in the top of the seventh while Matt Morash fired five innings, allowing just one earned run, as Westford Academy picked up a key 3-2 baseball road win over Dual County League rival Lincoln-Sudbury on Wednesday afternoon.

The Ghosts (13-0) have allowed more than two runs on just a pair of occasions this year.

“We knew going into today it would be a battle so I am really proud of the way our guys competed throughout,” Westford coach Mike Parent said. “We left a lot of runners on base early and it could have been a frustrating loss but we kept reminding our guys it’s a seven-inning game and they stayed composed.”

Westford held a 2-1 lead in the bottom of the fifth but a Matthew Stango RBI groundout tied the score. After Morash departed, Nic Bonica entered and threw a perfect sixth inning, sending the game to the seventh all even, 2-2.

In the decisive frame, McDermott reached on an error to begin the inning, moved over to second on a walk, and then advanced to third on a base hit by Tyler Frazee which loaded the bases. On the first pitch he saw, pinch hitter Dan Metznik connected on a sacrifice fly to bring home McDermott and give the visitors a 3-2 advantage.

The Warriors (8-7) got the tying run on base in the bottom of the inning when Logan Umbach singled, but Bonica got the final two outs to preserve Westford’s 13th consecutive win. Morash struck out eight and had a stretch at one point where he retired 10 consecutive hitters before turning it over to Bonica to finish the job.

“We’ve been conservative with our starting arms because we want our guys to be strong come June. I am very blessed to have five or six guys that I trust in key situations with Matt and Nic Bonica being two of those guys. There is not much dropoff there,” Parent said.

Lincoln-Sudbury grabbed a 1-0 lead in the bottom of the first when Jake Haarde singled and then scored on a Frankie DeTraglia sacrifice fly. The Ghosts tied the game in the third when Morash scored on a fielder’s choice and then took a 2-1 lead in the fifth on a Warriors’ defensive miscue.
