For the second year in a row, the Seton LaSalle girls opened the WPIAL playoffs with a Saturday game and noon tip-off at a higher-seeded Waynesburg team.

And just like last year, Seton LaSalle started slow and dug itself an early hole.

Only this time around the Rebels rallied for the win, making the hour bus ride back to school much more enjoyable.

Addie Lonergan knocked down six 3-pointers and scored a game-high 27 points as No. 11 Seton LaSalle used a dominant second half to upset No. 6 Waynesburg, 57-36, in a Class 3A first-round game.

After falling behind, 18-11, after the first quarter and 25-21 at the half, Seton LaSalle (14-8) outscored Waynesburg (20-3), 36-11, in the second half. Waynesburg, co-champion of Section 4, had won 12 of its previous 13 games.

“I just think our defense really stepped up in the second half, especially our help defense. The girls stepped up and were rotating over and guarding well. I think they were more mentally focused,” said Seton LaSalle coach Jordan Giles, whose team finished in a three-way tie for second place in Section 2.

A year earlier, Waynesburg, as the No. 8 seed, jumped to a 19-10 first-quarter lead before going on to beat No. 9 Seton LaSalle, 64-55.

But the rematch played out differently, with Lonergan playing a feature role by scoring 17 of her points and connecting on five of her 3-pointers in the second half.

“She was huge today,” Giles said of Lonergan, a sophomore and one of the WPIAL’s top perimeter shooters. “You could definitely tell she was comfortable today and was ready to go. We say that the 3 is actually her layup.”

Lonergan, Mallory Daly (14 points) and Tiara Curry (14 points) combined to score all but two of Seton LaSalle’s points.

Seton LaSalle also did an excellent job against Waynesburg’s Kaley Rohanna, the team’s leading scorer. Rohanna led the Raiders with 13 points but had only four in the second half. She poured in 31 in last year’s meeting.

Next up for Seton LaSalle is a matchup against No. 3 Beaver Falls in Wednesday’s quarterfinals.
