The Athletics announced (on Twitter) that they have traded right-hander Ronald Herrera to the Padres as the player to be named later in the Kyle Blanks trade. That deal, which was reached on May 15 this month, also sent outfielder Jake Goebbert to San Diego.
Herrera, 19, has spent the season in the rotation for Oakland’s Class-A affiliate in Beloit, pitching to a 3.38 ERA with 6.2 K/9 and 1.8 BB/9 in 50 2/3 innings of work. The Venezuelan hurler ranked 16th in the A’s farm system, according to MLB.com. Baseball America ranked Herrera 17th among A’s prospects prior to the 2014 campaign.
The A’s signed Herrera for just $20K out of Venezuela back in 2011 (as MLB.com’s Jonathan Mayo notes in his free scouting report on Herrera). Mayo writes that Herrera is exceptionally polished for his age and features three pitches, including a fastball that touches 94 mph despite his small frame (he is listed at 5’10″ and 168 pounds). Mayo also writes that Herrera’s changeup shows more promise than his curveball, and his fastball features some nice sink. Baseball America agreed in their 2014 Prospect Handbook, noting that Herrera has outstanding command and “has the makings of a solid big league starter” down the line.
