Prospect Voth throws seven scoreless for Potomac

Right-hander Austin Voth, rated the Nationals' No. 16 prospect by MLB.com, took a no-hitter into the sixth inning Friday and settled for throwing seven scoreless innings in Class A Advanced Potomac's 4-0 victory at Frederick.

Voth began the game by retiring the first 11 batters he faced. A two-out walk in the fourth inning to Trey Mancini gave Frederick its first baserunner, but the Keys would have to wait until Wynston Sawyer led off the sixth inning with a single for their first hit. Though they notched another hit against Voth, in the seventh inning, the Keys were unable to advance a runner past first base when he was on the mound.

Voth finished the night with a season-high eight strikeouts and won his second game since being promoted to Potomac last month.

After finishing second in the Pac-12 in strikeouts to Mark Appel last spring, Voth was picked in the fifth round of the 2013 First-Year Player Draft by the Nationals. They sent him to Class A Hagerstown to begin his first full professional season. He went 4-3 with a 2.45 ERA and 74 strikeouts in 13 starts with the Suns and earned a spot on the South Atlantic League All-Star team.

As good as he was in the first half, Voth has been even better since joining Potomac after the All-Star break. He has made four starts and is 2-0 with a 0.35 ERA and a 0.50 WHIP. He has struck out 28 batters and walked four in 26 innings.
