Marinez, Mike Dunn and Jose Ceda give the Marlins three young closer types if they ever decide to demote or part ways with stopper Leo Nunez. Marinez has an above-average fastball that sits in the mid-90s with good movement. Unfortunately, the 6-foot-1, 165-pound hurler has had trouble with his mechanics and throwing his slider consistently for strikes, which has resulted in an average of 7.20 walks per nine innings this season. The Dominican is a big-time talent but is still rough around the edges.
Martinez has as much upside as any hurler in the low minors. The 19-year-old fireballer can routinely dial up his fastball to the mid- to high 90s. The athletic Dominican complements his heater with two developing offerings in a changeup and curveball; both show plus-pitch potential. Making his North American affiliated debut this season, Martinez has gone 3-2, with a 2.33 ERA and a 50:14 strikeout-to-walk ratio in 38 2/3 innings.
Teheran is considered by many to be the top pitching prospect in all of the minors, and his lights-out performance of late only strengthens that argument. In the month of June, Teheran has gone 4-0, with a 1.00 ERA and a 31:2 strikeout-to-walk ratio in 36 innings. In fact, Teheran has not allowed a walk in his last four starts. The Columbian has three plus pitches and is ready for The Show (despite mixed results in his first MLB action), but the 20-year-old will have to wait patiently for his long-term turn as the Braves employ one of the deepest starting rotations in baseball.
Vizcaino probably has the second-highest ceiling amongst the arms in the Braves system which includes Teheran, Randall Delgado and Mike Minor. The 20-year-old features a low- to mid-90s fastball, a good changeup and a nasty curveball that serves as his bread-and-butter offering. Most importantly, Vizcaino already shows good command of all three offerings. In 71 2/3 innings between high Single-A Lynchburg and Mississippi, Vizcaino is 4-3, with a 3.01 ERA and a 72:21 strikeout-to-walk ratio.
