Giolito will look to continue those streaks Tuesday as he takes the mound for Hagerstown, facing West Virginia. First pitch is set for 7:05 p.m. ET.
West Virginia brings plenty of prospect firepower of its own to the matchup. The Power are led by outfielder Austin Meadows and catcher Reese McGuire, the Pirates' two first round picks in the 2013 First-Year Player Draft.
Meadows, the Pirates' No. 4 prospect and No. 49 on the Top 100, missed nearly all of the first three months of the season due to a hamstring injury he suffered in Spring Training. He didn't join West Virginia until July 12 and is hitting .301/.338/.356 with seven runs in 18 games.
McGuire, the Pirates' No. 7 prospect and No. 80 on the Top 100, has been with the Power all season. While the 19-year old hasn't hit quite as well as expected, he has earned praise for his work behind the plate. He is hitting .260/.303/.311 in 79 games.
After winning the first game of the series Monday, McGuire and Meadows will try to make it two in a row Tuesday. It won't be easy, however. Not only has Giolito been pitching well recently, the big right-hander has proven to be one of the best pitchers in the league all season.
The Nationals have closely monitored Giolito's workload since he underwent Tommy John surgery in 2012 and he hasn't thrown enough innings to qualify for the South Atlantic League ERA title. If he had, his 2.17 ERA and 0.96 ERA would be the best in the league. Even having thrown just 83 innings, he has struck out 94 batters, the 11th most in the circuit.
In addition to Giolito, several other pitchers ranked on the Top 100 are scheduled to start Tuesday, including Dylan Bundy (No. 15), Eddie Butler (No. 29), Mark Appel (No. 45), Michael Feliz (No. 98) and Alex Gonzalez (No. 99). Fans can watch Butler, Appel, Feliz and Gonzalez on MiLB.TV, beginning with Butler and Double-A Tulsa visiting Midland at 7:30 p.m. ET.
Appel, the Astros' No. 2 prospect, will be making his second start since being promoted to Corpus Christi. He threw five scoreless innings in his debut and will look to continue that streak Tuesday at 8:05 p.m. ET when he faces Northwest Arkansas and third Hunter Dozier, ranked No. 92 on the Top 100.
