Giolito fans 10 in 6 innings for Potomac

Nationals No. 1 prospect allows 1 run; leaves game following rain delay

Giolito fans 10 in 6 innings for Potomac

A rain delay may have cut Lucas Giolito's night short during Class A Adavanced Potomac's 10-inning 2-1 loss, but fans still got a show from baseball's No. 4 overall prospect.

The Nats' No. 1 prospect made his second straight "relief" appearance for rehabbing starter Aaron Barrett, who struck out the side in the first inning. Giolito, who entered in the second inning, kept the K parade going, striking out 10 Wilmington Blue Rocks while allowing just three hits, one walk and one run in six innings of work. With the score tied 1-1, the rain came down and forced the teams to seek shelter during the 34-minute delay in the eighth inning.

Giolito's performance was strong -- his 10 strikeouts were one shy of matching his career-high -- but it wasn't quite as impressive as last week's outing, when he subbed in for Barrett and proceeded to toss seven innings of no-hit ball. Entering Monday, he had a 10 1/3-inning no-hit streak, which quickly ended after he gave up on a Frank Schwindel double to lead off the second inning.

The Rocks put one on the board in that frame, but Nationals No. 9 prospect Drew Ward swatted a sacrifice fly to bring home Stephen Perez in the fourth and tie the contest. Wilmington's Cam Gallagher cracked his fourth homer of the year in the top of the 10th inning off of Derek Ward, who relieved Giolito. After a leadoff single, Ashton Goudeau retired three consecutive Potomac hitters to earn his fourth victory of the year.

Giolito has not lost since June 7, over which time he's allowed just two earned runs in 25 1/3 innings while striking out 30 batters. He stands at 3-4 with a 2.76 ERA in 11 appearances since leaving extended Spring Training.
