The Wild Things signed their fifth Class AA prospect in as many days agreeing to terms with former Washington Nationals pitcher Richie Mirowski.

The 25-year-old right-handed pitcher was drafted by the Nationals in the 45th round of the 2011 MLB June Amateur Draft. The Oklahoma Baptist University product spent four seasons in the Nationals system and had a career 17-6 record and a 2.37 ERA in 163 1/3 innings, all as a relief pitcher. In 101 relief appearances, he had 183 career strikeouts and registered a 3.45 strikeout-to-walk ratio.

Mirowski earned several promotions throughout his impressive career in affiliated baseball. After just 12 games with the Potomac Nationals in 2014, he moved to Double-A Harrisburg. He appeared in 10 games and recorded 12 strikeouts in 13 innings with the Senators last year.

In 2013, Mirowski went 8-3 with a 1.50 in 23 games for high Single-A Potomac. In 48 innings, Mirowski had 59 strikeouts and 11 walks yielding a .180 opponents’ batting average. Following his first career call up with the Senators in 2013, he struck out 29, walked four and held opponents to a .197 batting average in 20 2/3 innings.

In 2013, he pitched in the Arizona Fall League for the Mesa Solar Sox. He had a 2.25 ERA with 10 strikeouts and two walks in nine games.

Mirowski began his affiliated career in 2011 with the Auburn Doubledays and pitched back-to-back seasons for the members of the New York Penn League. After four games with the Doubledays in 2012, he was called up to the Nationals Class-A Hagerstown Suns, where he posted a 2.00 ERA in 16 games.
