With the win, GSU improves to 23-31 overall and 13-16 in the conference with one game remaining in the regular season.
The Panthers still sit one game back of Towson (14-15 CAA), but a Panther win Saturday at ODU coupled with a Tigers loss to James Madison would send GSU to its fourth straight postseason appearance.
GSU belted 14 hits in the win Friday, with Caden Bailey's 3-for-4 effort leading six Panthers with multiple hits.
Tomorrow's finale is slated for 1 p.m. at the Metheny Baseball Complex.
"This was one of the best-played games all season," head coach Greg Frady said. "It was also a lot of fun as everyone really contributed and played well. Now we come out tomorrow with our postseason life on the line."
The teams traded scores early as GSU grabbed a 3-1 lead following Scott Sarratt's fourth inning sacrifice fly.
The Monarchs scored once in the bottom of the inning and then struck for four more scores in the fifth, taking a 6-3 lead with Joey Burney's two-run single.
The Panthers would bounce back with the final five runs of the game, however, started by three in the sixth.
Wood doubled home Kolowich, Sarratt added another sacrifice fly and Bowder tied the game with a single back through the middle to plate Wood.
After Van Asch knocked his second double of the game in the seventh with two outs, Wood delivered the deciding blow with his sixth home run of the season, a no-doubt shot over the wall in left that put the Panthers in front, 8-6.
Meanwhile, Dyer had some of his best stuff of the year on the mound, holding the Monarchs to just one hit over the final 4.1 innings as the two-run cushion held for a GSU victory.
The Panthers now turn their focus to the Saturday finale, where senior Tyler Claburn (4-3) will take the mound.
GSU is one of only two conference schools to reach each of the last three CAA tournaments, only missing the postseason once in Frady's first five seasons.
