The 6-foot-6 righty spent the first month of the season at the Nats' Spring Training facility in Viera, Fla., after the organization decided to give him some extra rest. Giolito hit his innings limit last season while going 10-2 with a 2.20 ERA in 20 starts for Class A Hagerstown.
Thursday, he traded blows with Royals No. 26 prospect Cody Reed, who matched Giolito's six innings while tossing nine strikeouts and preventing any runs.
Ultimately, Wilmington prevailed in the pitchers' duel, 1-0. Reed, a southpaw, picked up the win to move to 3-2 with a 1.69 ERA. Giolito nearly cut his ERA in half as it dropped from 10.38 to 5.23 after the outing.
