One is a starter who does not throw hard. The other is a reliever, not a closer, just a reliever, who throws harder.
Miguel Chalas, rhp
Age: 22
Signed out of the Dominican Republic in 2010, Chalas reached Triple-A for his past two appearances, which could have been a showcase for the righthander, who had not pitched above high Class A in four years in the organization prior to that. Chalas throws a four-seam fastball from 90-93 and a fringe breaking ball described as a slurve. He’s pitched in relief the past two seasons after starting the first two in the organization and pitches largely to contact, averaging fewer than seven strikeouts per nine.
Mark Blackmar, rhp
Age: 22
The son of PGA senior golfer Phil Blackmar, Mark is an athletic 6-foot-3, 215-pound righthander with a three-pitch mix. His cutter/slider is his best pitch, and he also fills the strike zone with a lively 87-91 mph fastball and a developing changeup. He sliced his walks this season to 2.21/9, but, like Chalas, does not rely on the strikeout, whiffing just 5.30/9 in his minor league career.
