Pitching back-to-back complete games appeared to wear down Pallotti sophomore pitcher Imani Torregano.
Torregano gave up six walks and eight runs in the bottom of the fourth inning against Baltimore Lutheran Thursday as the Panthers lost a six-run lead.
"I could tell her arm was getting tired," Pallotti coach Katie Grenchik said.
After Pallotti rallied with four runs in the top of the sixth, Torregano ran into some more trouble in the bottom of the inning.
She walked the first two batters before striking out three of the last four to help the Panthers to a 12-11 victory in Towson in an Interscholastic Athletic Association of Maryland C Conference game.
The contest was shortened to six innings because it lasted more than two hours.
Grenchik likes to rotate Torregano with pitchers Kiley Sweeney and Lyndsey Llewellyn to keep them fresh, but she couldn't do that because the latter two were away on spring break.
For the second game in a row, Pallotti (3-4 overall, 3-2 league) had only nine players. The Panthers beat Oldfields, 19-4, Wednesday.
None of that seemed to matter as Pallotti built a 7-1 lead against Lutheran (0-3, 0-1) through the top of the fourth.
The Panthers scored two in the first, one in the second, two in the third and two in the fourth.
Alyssa Meyer highlighted the fourth with a two-run double, which scored Francesca Giuliani and Katy Allison. Lutheran starting pitcher Lauren Kiper, a senior, had to come out of the game in that inning after getting hit in the head with a line drive. She was replaced by Heather Kritchfield.
Pallotti's lead quickly disappeared in the bottom of the inning as the Saints pushed across eight runs.
Lutheran sent 13 batters to the plate, took advantage of six walks and two errors and got two-run singles from Mandy Dietz and Kritchfield.
Pallotti, however, responded in the sixth with four runs to go ahead, 12-11. Allison's single to right field knocked in Giuliani, the winning run.
Torregano was wild in the bottom of the sixth, loading the bases on walks, but she wiggled out of the jam.
"She finished strong," Lutheran coach Kirby Freese said. "She buckled down and got the strikeouts she needed. Our batters just couldn't make contact."
