PORT CHARLOTTE, Fla. -- Denison erupted for four runs in the eighth en route to a 9-5 victory against 12th-ranked Heidelberg on Saturday.

After surrendering a three-run lead in the seventh, Denison answered in the top of the eighth. Andrew Mahle led off the inning with a base hit to right. With one down, Evan Nicholson and Tim Duxbury logged back-to-back singles to load the bases. Stepping up to the dish in a key situation, Justin Vaske hit a two-run single to right center to give DU a 7-5 lead.

After a Heidelberg pitching change, Jeremy Tirado drove in Duxbury on a fielder's choice to the shortstop. With two on and two down, a single by Tyler Nicholson plated Tirado from second and put the Big Red on top 9-5. Reliever Chris Fries retired the side in order in the bottom of the eighth, while Philip Seay secured the win in the ninth with a strikeout, fly out and ground out.

Heidelberg opened the scoring in the second frame with an RBI single by Joe Staab. The Big Red took the lead in the fourth when a throwing error by pitcher Bryan Peters allowed Tyler Nicholson and Danny Kraus to score. In the bottom of the fifth, an errant throw home by Peters allowed Vaske and Tirado to cross the plate. Denison made it a 5-1 game when a Krause sacrifice fly to right drove in Drew Rice.

Arneal Squibb opened the bottom of the fifth with a triple and eventually scored on a wild pitch. In the seventh, a two-out rally by the Berg tied the game at 5. Andrew Zenczak scored the first run on a wild pitch, while Steven Kisan came home on a balk. Ross Pruitt tied the game with an RBI single to center that plated Austin Fleming.

Fries picked up the win after tossing 1.1 innings of hitless baseball. Denison starting pitcher Tyler Vaske scattered six hits and allowed two runs in the no decision. He also struck out a career-high 10 batters in five innings. Heidelberg reliever Teddy Lowe suffered his first loss of the season after allowing four runs on four hits in 2.1 innings.
