Five of Giacolone's seven stops came in the second half to buoy the Irish defense. Head coach Christine Halfpenny's thoughts: "I'm so excited for this 2019 team. They've really done so many incredible things. Today was a big program win to earn that fifth ACC regular season victory. Getting that fifth conference win reflects on the path and trajectory that this program has been on. Today was also a total team effort. Everybody was ready when their number was called, and stepped up to make big plays. I'm really proud of the continued belief this entire group displays in each other day in and day out." Nikki Ortega's thoughts: "I thought we really moved the ball well and attacked from all points of the offense. We really wanted to get that fifth ACC win, and to do so on the road is really special." Savannah Buchanan's thoughts: "We knew coming in that the draw was going to be perhaps the most important part of this game. As a group, we worked really well together today to control draws and scoop up loose ground balls. To get five ACC wins, something that hasn't been done before here, is really special and I'm proud to have done it alongside this group of people." NOTABLE NUMBERS The Irish earn five ACC regular-season wins for the first time since joining the conference in 2014. The Irish held an opponent under 10 goals for the 10th time this season. The eight draw controls by junior Savannah Buchanan ties her season-high (2/14 at Marquette) and are just one shy of her career-high (9 vs. Detroit Mercy, 2/11/17) Senior Samantha Giacolone earned her 13th victory in goal this season for the Irish, and has most career wins in goal in program history with 46. Sophomore Maddie Howe has now recorded a hat trick in 10 games this season. Sophomore Andie Aldave has 122 draw controls in 2019, and 220 for her career. UP NEXT The Irish (13-2, 5-2 ACC) close the 2019 regular season next Saturday (April 20) at home vs. Northwestern for Senior Night. That contest is set for 7 p.m. ET at Arlotta Stadium and the matchup will be streamed live on ACC Network Extra.
