Matz (7-1) threw eight shutout innings, allowing four hits, striking out seven and walking one in a 2-0 victory over the Nationals on Wednesday.
The lefty was hitting all his spots, inducing 28 called strikes. After the second inning, Matz didn't allow another base runner to reach second, and at one point, he retired 15 straight batters. Since allowing seven runs over 1.2 innings during his first start of the year, Matz has yielded just six runs in his last 48 frames. His next start will be Tuesday against the White Sox.
