The win helped the Wildcats (31-21, 13-15 SEC) clinch a spot in the upcoming league tournament. Only 12 of the 14 SEC programs qualify for a spot in the tourney.
Reed (10-2) allowed just three hits and walked two while striking out three Bullogs. He retired 14 of the final 16 batters he faced.
The junior left-hander was supported by a UK offense that exploded for 19 hits against three Georgia pitchers, including four of his own. Reed, perhaps the leading national player of the year candidate, raised his season avergage to .353 to go along with 13 doubles, 21 home runs and 65 RBI.
Kentucky's Max Kuhn also had a big night at the plate, going 4-for-5 with two doubles and four RBI. Ka'ai Tom stayed hot with two hits, including his second home run of the season, and drove in three runs.
The Cats broke open a scoreless game in the fifth inning and plated runs in each of their last five at-bats with the help of a Georgia defense that committed five errors on the night. UK scored five times in the seventh inning and added four more in the eighth to blow the game open.
Ryan Lawlor (4-6) took the loss for the Bulldogs, allowing five earned runs on 11 hits over 6.1 innings.
Georgia dropped to 25-27 overall and 10-17-1 in the SEC. The Bulldogs are a half game ahead of Auburn for the final spot in the SEC Tourney.
The series resumes Friday at 7 p.m. ET. The last two games could have a big impact on UK's tourney seeding, which could fall anywhere between the 6 seed and the 11.
