A look at the marquee pitching matchup set for Delmarva's Perdue Stadium today

This is the South Atlantic League's version of Chris Tillman against Justin Verlander. Tonight when the Single-A Delmarva Shorebirds host the Hagerstown Suns in Salisbury, top pitching prospects Hunter Harvey and Lucas Giolito will oppose each other. This marquee matchup was to take place at 7:05 p.m., but after a rainout last night, it will now take place in first game of a doubleheader starting at 5:05 p.m. at Perdue Stadium. Harvey and Giolito are both hard-throwing 19-year-old right-handers with potentially very bright futures at the top of rotations. Both were drafted in the first round. Both have been ranked among the top 50 prospects in the sport. Through his first two starts for Delmarva, Harvey is 1-0 with a 1.64 ERA. He started his Shorebirds season with 10 consecutive shutout innings before he gave up a homer and two runs in his fifth and last inning of his last start. Harvey was the Orioles' top pick last June, drafted 22nd overall. He is rated by Baseball America as the Orioles' No. 4 prospect. He is ranked No. 43 in ESPN's top 100 and No. 58 by Baseball Prospectus. At this very early stage of his O's career, Harvey has put up some dazzling numbers. Counting last season and his five no-hit innings in a playoff game for short-season Single-A Aberdeen, Harvey is 1-1 with a 1.52 ERA. Over 41 1/3 innings he has given up 28 hits and seven runs with nine walks and 51 strikeouts. Here is Baseball America's scouting report on Harvey: "After turning pro, Harvey impressed at short-season Aberdeen, then was at his best in the New York-Penn League playoffs, when he threw five no-hit innings against Tri-City. His fastball sat 93-94 mph and touched 95 in that start, and peaked at 97 early in the spring. He has smooth mechanics that should allow him to maintain premium velocity as he fills out. His sharp curveball earns plus grades at its best. Aberdeen manager Matt Merullo described him as 'intimidating, not intimidated.' Harvey seldom threw changeups in high school but has shown potential with that pitch. He showed the poise and mound presence of a much more experienced pitcher." The Nationals drafted Giolito with the 16th pick overall in the 2012 draft out of Harvard-Westlake High School in Studio City, California. He underwent Tommy John surgery on Aug. 31, 2012, but he returned to game action about 10 months later in the Gulf Coast League and his fastball quickly returned. He touched 100 mph in the GCL last summer. Giolito is 1-0 with a 3.38 ERA through two starts for Hagerstown. He went three innings giving up four runs in his first outing but pitched five scoreless innings of one-hit ball in his last start. Giolito is the higher rated prospect. He is the Nationals' No. 1 prospect and ranked No. 13 overall by Baseball Prospectus, No. 21 by Baseball America and ESPN and No. 42 by MLB.com. Here is Baseball America's scouting report on Giolito: "The first three pitches out of Giolito's hand in his 2013 GCL debut were 100 mph fastballs. His fastball routinely ranges from 93-100 with exceptional downhill angle, and he learned by the end of the summer that he was more comfortable and had better command when he sat at 95-97, rather than reaching back for triple digits all the time. Between his velocity and his angle, Giolito's fastball rates as a true 80 pitch on the 20-80 scouting scale, and he does it with minimal effort. He also throws a 12-to-6 power curveball in the 84-86 range that Nationals pitching coordinator Spin Williams has called one of the best curves he's ever seen when Giolito throws a good one. It has late bite and excellent depth, projecting as a plus-plus pitch with a chance to be a second 80 offering. Giolito is still learning to control his 6-foot-6 body, and his delivery is not always in sync. When he throws his 82-83 mph changeup with conviction, it flashes plus, but it remains a work in progress. Giolito also stands out for his competitive mound demeanor and tireless work ethic." This should be a fun game to watch later today and it sure has attracted some attention within minor league circles. I'll be at Perdue Stadium to cover the game and check this blog and my Twitter feed later today and tonight for updates from Salisbury.
