The son of Fernando Hernandez, who pitched in two games for the 1997 Tigers, Jonathan was born in Memphis while his dad was in Double-A but grew up in the Dominican Republic. Signed for $300,000 in January 2013, he made an initial impression with his advanced feel for polish for a teenager. His velocity jumped once he got to full-season ball in 2016 and he now has some of the best pure stuff in the system, though he's still learning to harness it.
After sitting around 90 mph with sink on his fastball earlier in his career, Hernandez now deals at 93-97 mph and can reach 99, getting groundouts with his two-seamer and throwing his four-seamer by hitters up in the strike zone. His slider has gotten quicker as well and now grades as a plus pitch that can lock up right-handers, and he has an effective curveball as well. His changeup has also improved, with its tumble helping him handle left-handers, though it can get a bit firm at times.
To become a mid-rotation starter, Hernandez will need to pair his present stuff with his previous control and command. He got knocked around in Double-A in the second half of 2018 because he couldn't locate his pitches as well as he needed to. He has a history of starting slow and then adjusting to each new level, so the Rangers are eager to see how he fares in '19.

How this works: Every pitch is affected by the forces of gravity, which means that every pitch drops on its way from the mound to the plate. These numbers are reported with gravity, which makes them larger and different than other pitch movement numbers you may have seen. Since gravity requires time, and slower pitches aren’t ‘better’ just because they have more time to move, the movement of a pitch is compared to ‘average’ movement by comparing it to other MLB pitch types within +/- 2 MPH and from within +/- 0.5 feet of extension and release.
