WINSTON-SALEM, N.C. -- Wake Forest used a dominant start by Parker Dunshee and a late offensive outburst to cruise past No. 4-ranked Florida State, 9-0, on Friday night at David F. Couch Ballpark.

After holding a narrow lead for much of the contest, the Demon Deacons (21-16, 6-10 ACC) broke the game open in the late innings, scoring three in the sixth, one in the seventh and four more in the eighth on Ben Breazeale's first-career grand slam, the team's first of the season.

In defeating Florida State by nine runs, Wake Forest picks up its biggest margin of victory over a top-five team this century.

The nine-run offensive output was more than enough for Wake Forest ace Parker Dunshee (5-3), who earned his team-leading fifth win by firing 7.0 innings of two-hit, shutout ball, to go along with four strikeouts.

Wake Forest began the scoring in the third on Jonathan Pryor's first homer of the year, an opposite field shot leading off the third. Pryor went 2-for-3 with two walks and two RBIs.

Dunshee held the Seminoles (22-10, 9-3 ACC) hitless into the fifth. Their first hit came leading off the inning, but Florida State left fielder Jackson Lueck was thrown out trying to stretch to a double by Kevin Conway.

The score remained the same until the sixth, when the Deacs brought home three more on an RBI single by Pryor and two-run knock from Nate Mondou to chased Seminole starter Mike Compton (4-2) from the game.

Conway added a sacrifice fly in the eighth before Breazeale erased any doubt with his grand-slam, a towering shot to right-center that gave the Deacs a 9-0 lead heading to the ninth.

Right-hander Donnie Sellers finished the game with 2.0 scoreless frames in relief.

Gavin Sheets and Keegan Maronpot each had a hit and a walk, while Johnny Aiello drew a pair of walks, reaching base for the 21st straight game.

The win Friday night allowed Wake Forest to improve to 5-0 in Friday night home games this season. The Deacs also have thrown back-to-back shutouts in ACC Friday night home games, as they beat Duke 12-0 on March 25. Wake Forest is 15-4 at home this year.
