Dayton, Ohio -- Youngstown State tallied nine hits, including a pair of home runs, but the Penguins allowed five unearned runs and dropped the series finale to Wright State, 8-7, on Sunday afternoon.
The Penguins fall to 11-18 overall and 4-4 in the Horizon League while the Raiders improve to 10-24 overall and 6-2 in the league.
Freshman Stevie Taylor went 2-for-3 with a home run and two RBIs while classmate Kelly Thompson-Cappadocio also went 2-for-3. Senior Kayla Haslett hit her first career grand slam and the 13th in the program's history.
After giving up three runs in the first two inning to fall behind, 3-0, Taylor led off the top of the fourth inning with a solo home run, her fifth of the year, to get the Penguins within two, 3-1.
The Penguins used a six-run fifth inning to take a 7-3 lead. Alexandria Gibson led off the inning with a walk and Sarah Dowd singled to put runners at first and second. After a sacrifice bunt by Brittney Moffatt and an intentional walk by Miranda Castiglione, pinch-runner Alexa Schmidt scored on a sacrifice fly by Taylor and Dowd scored on the dropped fly ball.
Thompson-Cappadocio walked to load the bases and Haslett belted a 3-2 pitch over the left-center field fence to give the Penguins a four-run advantage.
