Addy Kostrencich was an eighth grader the last time the Palos Verdes softball team beat Mira Costa.
On Friday, Kostrencich played a huge role in helping PV end its five-game losing streak to Mira Costa.
The junior drove in four runs, and freshman Holly Stiebel scattered five hits to help PV defeat Mira Costa 8-2 in a Bay League showdown.
"This win was huge for us. It's something we've been wanting to do," Kostrencich said. "I'm very proud of Holly for being able to hold (Mira Costa)."
Stiebel's lone walk of the game came back to bite her in the first inning. She walked Mustang leadoff hitter Katie Katsuyama before Katsuyama scored the first run of the game on an error.
"I just needed to tell myself I have to believe, and I knew I'd stay in the game," Stiebel said. "Everything will turn out OK."
PV (13-7, 4-1) struck back quickly, as Brooke Stiebel and Amanda Treatch notched two-out RBI singles to give the Sea Kings a 2-1 lead.
Mira Costa (13-11, 4-1) tied the game at 2 in the third. With two outs, Neri Piper doubled before scoring on Emma Fong's single.
Just like it did in the first inning, PV responded in the fourth.
Morgan Fresch reached on an error, and on the second pitch of her at bat, Kostrecich lined Katsuyama's offering over the left field fence for a two-run home run to give the Sea Kings a 4-2 lead.
"I was looking inside, and (Katsuyama) threw me an inside drop ball," Kostrencich said. "I've been struggling with the bat, and I just wanted to stay through the ball, get my hands in and hit something up the middle."
PV was back at it in the fifth. After loading the bases with one out, Morgan Fresch walked to give PV a 5-2 lead.
Up again with a chance to do damage, Kostrencich lined a two-run double to left that gave the Sea Kings a 7-2 lead.
"Addy was dialed in (Friday)," PV coach Pat Fresch said. "She's been pitching well, but has been up and down at the plate. It's great seeing her lead us at the plate."
While the PV offense was giving her runs to work with, Stiebel continued to make Mira Costa's hitters work.
"We have to play fundamental softball, and we have to make adjustments sooner at the plate," Mira Costa coach Brittany Gardner said. "We were making the same mistakes in our first at bats that we were in our third, and we didn't adjust."
Of the five hits she allowed, one came in the first, two came in the third and the last two in the sixth.
"My curveball and change-up were my best pitches," Stiebel said. "It's definitely a big relief having the lead, not being afraid to walk batters and just going after them."
