Davis (11-2) was dominant on the mound and Washington (40-15-1) had 11 hits.
Washington pushed ahead 1-0 in the first inning and then broke it open in the fourth with four more runs. The Huskies scored all of their runs in the fourth with two outs.
Braden Bishop and Brandon Berry each had three hits.
Georgia Tech (36-26), which won the Atlantic Coast Conference tournament championship last weekend, couldn’t capitalize on that momentum. Josh Heddinger (4-5) took the loss, giving up five runs over 5 2-3 innings.
