Giolito dominates for Double-A Harrisburg

Nationals No. 1 prospect (No. 3 overall) Lucas Giolito was nearly perfect on Friday, setting down 17 straight batters in Double-A Harrisburg's 2-0 win over Bowie.

The 6-foot-6 right-hander allowed one hit through seven innings of shutout work, striking out 11, which tied his career high, on the night. Early on, Giolito recorded K's on six straight outs between the second and third innings and his only slip-ups were a single allowed to Bowie's Chance Sisco and a plunking of Mike Yastrzemski, the Orioles' No. 13 prospect.

Prior to Friday's start, Giolito had been serviceable in three outings for Harrisburg. The 21-year-old entered the game with an 0-1 record and a 5.94 ERA, but left with a .500 mark and a much lower 4.18 ERA.

He missed the first month of the season while in extended Spring Training, but was efficient at Class A Advanced Potomac. The 2012 first-rounder went 3-5 with a 2.71 ERA in 13 appearances for the P-Nats before getting promoted in late July.
