The Pirates have released minor league pitchers Christopher De Leon and Gerardo Navarro, this according to Pirates Prospects John Dreker.
De Leon was signed by the Bucs out of the Dominican Republic in 2010. After being used mostly as a starter, he pitched exclusively as a reliever beginning in 2013. De Leon spent six seasons in the organization pitching in some capacity of rookie ball (Dominican Summer League and Gulf Coast League). He posted a 2.87 ERA with a 1.23 WHIP. De Leon had significant control issues with a 4.9 BB/9.
Navarro signed with the Pirates out of Mexico three years ago. The 22-year-old lefty pitched for the DSL Pirates in 2013 and the GCL Pirates in 2014 and 2015. Navarro combined to put up a 3.90 ERA along with a 1.22 WHIP in 39 games, 13 of which were starts. His fastball was only in the high-80’s and he registered just a K/9 ratio of 4.9.
