SPRINGFIELD — His team on the ropes after his first subpar pitching performance of the season, Lucas Stone desperately wanted to redeem himself at the plate.

SPRINGFIELD — His team on the ropes after his first subpar pitching performance of the season, Lucas Stone desperately wanted to redeem himself at the plate.

"I was just really determined to do something productive," he said.

Stone did much more, blasting a grand slam home run to tie the game in the fifth, as the third-ranked Ashland High baseball team stormed back from a 7-1 deficit to stun 10th-ranked Thurston 8-7 Friday in the Class 5A state quarterfinals.

The win advances Ashland to the semifinals for the fourth year in a row. The Grizzlies (23-5) will host Madras (22-8), the No. 2 seed from the Intermountain Conference, on Tuesday at North Mountain Park. Madras beat Crater 11-3 in another quarterfinal game Friday.

Thurston, the defending state champion, scored seven runs off Stone on nine hits to build a comfortable six-run cushion, but Ashland cut the deficit to four and loaded the bases for Stone with nobody out in the top of the fifth. The senior came through, belting his third homer of the year over the fence in left-center to give the Grizzlies new life.

Ashland scored the go-ahead run in the top of the seventh on Ethan Schlecht's sacrifice fly. The drive was caught in foul territory plenty deep enough to score Luke Baldrica, who led off the inning with a double and moved to third on an error.

"The boys gathered (heading into the fifth inning) and they said that they were not going to lose this way," Ashland head coach Don Senestraro said. "I'm just so proud of them."

Baldrica went 4-for-4 and scored three runs to lead the Grizzlies at the plate, while Jake Scarminach and Brent Hegdahl each went 2-for-4.

MADRAS 11, CRATER 3 — At Madras, Turner Gill pitched two-hit ball over five scoreless innings and had three doubles and three RBIs as Madras ended Crater's playoff run in the quarterfinals.

Trailing 11-0, the Comets bunched four of their six hits to score all three runs in the sixth inning.

Bryce Crawford opened the rally with a single, then was erased on a fielder's choice by Sebastian Reynolds. Christian Massey singled and Corey Wynant followed with an RBI double. Andrew Tracy's sacrifice fly scored Massey and Derek Cartwright singled home Wynant to complete the scoring.

Crawford had two hits for the Comets, who finished the season at 14-16.

Class 3A Playoffs

GRANT UNION 7, CASCADE CHRISTIAN 6 — At John Day, Cascade Christian had a chance to tie or take the lead in the sixth inning of the state quarterfinal game, but the Challengers couldn't get a key one-out hit with the bases loaded.

The Challengers (15-11), the No. 2-seed from the Sunset League, strung together four singles with two walks to score three runs in the sixth and cut their deficit to 7-6. Nolan Villanueava and Zach Smith produced RBI singles during the rally.

Colton Cochran went 3-for-4 and scored twice to pace the Cascade attack. Villanueava added two hits and two RBIs and Smith had two hits and drove in one.
