Touting Rangers prospect Martin Perez

Keith Law got a chance to see Rangers pitching prospect Martin Perez and came away impressed. Some of Law's blog on Perez:

• I'd seen Texas lefty Martin Perez (the No. 18 prospect in my most recent top 100 ranking) before, but had always left wanting to see a little more -- scouts and execs would tell me they'd seen a version of him that I never quite caught. I think I caught that one on Tuesday, however, as he was lights-out, 92-95, getting the ball in on hitters, hitting 95 to the glove side like he was walking down the street. His changeup at 83-85 showed both good arm speed and hard fading action, and his curveball was average to a tick above, 72-76 with varying angles, some true 12-to-6 downers and some with more traditional two-plane break. His body also looked better, more mature and stronger, and his command was excellent. This is the guy who I had in my preseason top 10 going into 2010.

Law's thoughts on Barret Loux:

• Texas right-hander Barret Loux threw on an adjacent field, but his stuff wasn't as good as Texas execs had reported from previous outings. I had Loux at 87-91 with an ordinary mid-70s curveball and an average changeup; he's got good size and his arm works fine, but he has major damage in his shoulder and elbow that led Arizona to void their deal with him last June. The Rangers have every incentive to push him as quickly as his performance allows, and if he's 90-94 as he was earlier in the month, they'll be able to do that. If he's working with fringy stuff like I saw, they won't.

And a quick few sentences on Jurickson Profar:

Profar is more lithe and quick, with quick hands and good plate coverage. I'd be surprised to see him develop much power but hands like those should lead to lots of contact and a high average. He was just 4.33 down the line, less speed than I expected to see from him.
