Last weekend the Boston University softball team showed what it can do when firing on all cylinders, as the Terriers won all four games and dominated their opponents across the board. In extending their winning streak to eight games Wednesday afternoon with 7-2 and 3-0 victories over Sacred Heart University, however, the Terriers proved something even more important: They can get the job done without everything working to perfection.

Junior pitcher Brittany Detwiler wasn’t at the top of her game when she toed the rubber for the opener against the Pioneers. Freshman leadoff hitter Shayne Lotito and senior slugger Liz Alley didn’t supply the offensive firepower BU saw from them during the first six games of the winning streak. But the rest of the team stepped up, as the Terriers won with solid pitching, outstanding production from the bottom of the lineup and sound defense.

Detwiler and freshman pitcher Cassidi Hardy, who on Monday was named the America East Pitcher of the Week and Rookie of the Week, each tossed complete games for BU. While Detwiler has been better, she certainly didn’t disappoint against Sacred Heart. Detwiler struck out eight Pioneer batters while allowing two runs on seven hits and two walks.

“[Detwiler] didn’t have her best stuff. She wasn’t as sharp as she probably wanted to be,” said BU coach Shawn Rychick, going on to laud his ace’s mental toughness. “She was able to win without her best stuff.”

Hardy, on the other hand, continued to overpower the opposition. The shutout was her third in a row, and she fanned six Pioneers and surrendered only three hits while walking a pair.

“Our two pitchers right now are going back and forth,” Rychick said, noting that Detwiler and Hardy seem to be thriving off each other’s consistent performances. “It’s good to see right now.”

Also good to see was the production the Terriers received from the bottom third of their lineup, especially without much contribution from Lotito and Alley. Lotito went hitless in seven at-bats with four strikeouts, while the Pioneers held Alley, BU’s all-time home run leader, to a single in five at-bats with three strikeouts.

But rookie shortstop Melissa Dubay came to the rescue, along with sophomore left fielder Molly Gallagher and freshman third baseman Brooke Hudson – the Terriers’ seventh, eighth and ninth batters, respectively. Dubay went 2-for-5 with a double, two runs scored and a run batted in. Gallagher went 2-for-4 with a sacrifice bunt, a run scored and a stolen base, while Hudson went 2-for-5 with a double, two runs scored and one RBI.

“[Dubay, Gallagher and Hudson] really create more opportunities for us,” Rychick said. “They’ve done a good job getting to pitchers and working counts. It’s wearing down pitchers some more. We’re putting the pressure on.”

That pressure translated into an exceptional day at the plate for freshman catcher Christy Leath. Batting third, Leath often came up with runners on base and didn’t fail to drive them in. She finished 4-for-7 with a double and four runs batted in.

BU’s defense was also stout throughout both games, but it was never better than in the third and fourth innings of Game Two. Junior second baseman Brandi Shields made a great stop in the hole between first and second and fired to Alley to retire the Pioneers’ first batter of the third. Hudson flawlessly handled three sharp grounders in a row. Lotito made the most dazzling play of the day, though, when she raced in from center field to make a diving catch on a sinking Sacred Heart line drive in the top of the fourth.

Rychick attributes much of his team’s success to the Terriers’ defensive prowess.

“[Hudson] made some great plays. She’s been very impressive,” Rychick said. “We’re making big plays when we need to. The more we continue to do that behind our pitchers, the better they’ll be. And hitting is great, but pitching and defense win championships.”

So does the tenacity BU demonstrated in sweeping the doubleheader — even without its best stuff.
