In a South Atlantic League pitchers' duel that lived up to expectations Wednesday, the Orioles' No. 4 prospect Hunter Harvey slightly edged the Nationals' No. 1 prospect Lucas Giolito. But both young aces were long gone from the game by the time Delmarva defeated Hagerstown, 1-0, in walk-off fashion in the 15th inning.
Harvey, the Orioles' 2013 first-round pick, struck out seven batters in six shutout innings. The right-hander retired the first seven batters of the game before giving up the lone hit he allowed on the afternoon.
Through three starts this season with Delmarva, Harvey has a 1.06 ERA and an 18-to-4 strikeout-to-walk ratio in 17 innings.
Giolito, the Nationals' 2012 first-round pick, was also in peak form Wednesday. The right-hander allowed two hits in five shutout innings and struck out six.
But even with Harvey and Giolito out of the game, neither team's offense was able to break through for a run until the 15th inning. First baseman Trey Mancini started the winning rally with a two-out single and scored two batters later when third baseman Drew Dosch lined the game-winning hit to left field. Like Harvey, Mancini and Dosch are members of the Orioles' 2013 Draft class.
