Davies hit two-run homers in the first and fifth innings for the eighth-seeded Yellow Jackets (33-24). His second shot put Georgia Tech up 5-0.
James Ramsey had three hits for top-seeded Florida State (43-13). His run-scoring sacrifice fly capped a three-run fifth, and his solo homer with two outs in the ninth made it a one-run game before reliever Alex Cruz got Jayce Boyd to fly out to end it for an NCAA résumé-building postseason win for the Yellow Jackets.
“I would certainly hope it enhances our cause,” Georgia Tech coach Danny Hall said. “Let’s put it that way.”
Winning pitcher Buck Farmer (8-3) struck out six in six innings.
“After you just sit there and watch your team get the lead, it makes you feel pretty comfortable,” said Farmer, a first-team All-ACC pick, who improved to 1-1 with a career 3.15 ERA vs. the Seminoles. “You can throw strikes and know you have your offense behind you.”
Florida State starter Scott Sitz (3-3) was charged with four runs in 4⅔ innings.
The Yellow Jackets are 1-0 in Pool A after their fifth Top-25 win during the past month. The Seminoles had their four-game winning streak in the series snapped.
The win is Georgia Tech’s first over a No. 1-ranked team since April 10, 2011, an 8-6 victory at home over Virginia, and the first to open ACC championship pool play since beating North Carolina State, 10-9, in 2008 at Jacksonville, Fla.
The Yellow Jackets had lost three consecutive tournament openers since.
Georgia Tech joins North Carolina State (2001) and Wake Forest (1985) as No. 8 seeds that have knocked off the No. 1 seed in the tournament.
