Here is the scouting report I wrote about Mijares for the John Sickels Baseball Newsletter, after I saw him pitch for Beloit in June.
I had never heard of this guy, and I doubt you have either, but if what I saw on Thursday is any indication, he is going to make some noise.
A Venezuelan signed in 2002, Mijares made his first start for Beloit Thursday after two relief appearances. Fastball was 88--94 MPH, average 92, with movement. His teammates told me he was timed at 98 MPH in a previous relief appearance. Even if that is an exaggeration, he showed more than enough stuff to succeed.
Slider at 83-86 MPH, curveball at 76-79 MPH, changeup at 76 MPH. His command is good, and he mixed his pitches very well. Has a 12/5 K/BB in 10 innings thus far, and has allowed only 5 hits. He has an EXCEPTIONAL pickoff move, picking off three runners in five innings of work. He needs to polish up his control, but his delivery is clean and I really like his long-term potential. Nobody has heard of this guy yet, but I think that is going to change.
Mijares posted an extremely impressive +81 percent K/IP ratio at Beloit. He's got very good stuff, and if he can throw strikes more consistently, he will emerge as a top-notch prospect. It remains to be seen if he's a starter or reliever, but he is definitely worth tracking. Grade B-.
