Solis has a 1.59 ERA for the month of May after appearing in 10 games to throw 11.1 innings.
Solis is showing signs that he's on the way to becoming the reliever that the Nationals hoped he could be when they drafted him in 2010. His opponent batting average is down to .125 from 2015's mark of .291 and his K/9 has risen by 1.83 to 9.00. With a BB/9 of 5.14, Solis's control is the main part of his game that is questionable. However, most of that damage game from a three game skid where he walked five batters in 5.2 innings. With a 3-year BB/9 average of 1.69, there's plenty of reason to believe that Solis will recover and hold his part as a reliable mid-inning contributor.
