MOOSIC, Pa. --  Baldwin Wallace University  won its school-record 29th game of the season and defeated Wesleyan (Conn.) University, 9-7,  in the Mid-Atlantic Regional championship game and qualified for its first appearance in the Division III Championships.

The Yellow Jackets (29-18) utilized three "quality starts" from its pitching staff and timely hitting to go undefeated in regional play. With the loss, seventh-seed Wesleyan ended its season at 31-13 overall.

"This was a total team effort," said BW fourth-year head coach Brian Harrison, who won his 100th game as a Yellow Jacket (100-61 overall). "We got solid starting pitching, including three quality starts, our bullpen was effective and we got good timely hitting and played mostly solid defense.

"This is great for our student-athletes, and especially the seniors, good for Baldwin Wallace University and definitely good for our baseball program," said Harrison. "We look forward to the challenge in Appleton."

BW's record-setting win extended its single-season school-record for victories. The Jackets set the mark of 27 in both 2012 and 2013.

"Records are nice," said Harrison, but that's something that we have to put in the back our minds right now. "Our focus has to be on the next game with the ultimate goal of winning the Division III national title."

The Yellow Jackets jumped out to a 1-0 lead with a run in the bottom of the first inning when Brad Gugliotta led off with a walk and later scored on a ground out.

In the top of the second, Wesleyan scored six runs on three hits, three walks and an error to take a 6-1 lead. The Yellow Jackets stung back for a run in the bottom of the fourth to close the deficit to 6-2 when Joe Hiller scored on a single by Jerry Scholle and after the Wesleyan center fielder misplayed the hit.

In the bottom of the sixth, BW scored four times to tie it at 6-6. Scholle led off with a single and then stole second base. After two outs, Gugliotta had an infield single and when the shortstop's throw short-hopped the first baseman, Scholle headed for home. The first baseman picked up the loose ball and threw home, but his throw hit the catcher's mask and Scholle scored to make it 6-3, and Gugliotta advanced to second.

Mark Zimmerman followed with a triple to right center field to score Gugliotta to cut the deficit to 6-4. Chontos followed with a single to score Zimmerman to make it 6-5. Hunter Handel ended the scoring when he doubled home Chontos to tie the game.

Undaunted, Wesleyan came right back in the top of the seventh to take a 7-6 lead with an infield hit, a sacrifice bunt and a two-out single.

BW came back in the bottom of the seventh to take a 9-7 lead as Eric Murphy singled to lead off the frame and moved to second on a passed ball. After two outs, Murphy scored the tying run on a single by Alex Green. After Green moved to second on the throw home, he scored the go-ahead run when Gugliotta reached base via a throwing error and advanced all the way to third. He then scored on a wild pitch to give BW a 9-7 lead.

At the plate, BW outhit Wesleyan, 13-8. The Jackets were led by Zimmerman, Chontos, Murphy, Scholle, Gugliotta and Handel.
