Beavan is a 6’7" control artist currently pitching in AA Frisco. In 110 innings, he has allowed just 12 bases on balls. He was a first-round pick in 2007 that lost some speed on his fastball in his transition to the pros.
That “stuff” is a four-seam fastball that touched 95-96 mph as an amateur, but hasn’t seen that velocity as a pro. In fact, his velocity had reportedly dropped into the 89-91 range at one point. It’s starting to come back, though, as I had him consistently at 90-93 mph.
Seattle seems to like tall, athletic pitchers that maybe are not there yet but have loads of potential. Beavan has a two-seam and four-seam fastball along with a slider. I’m in no position to project Beavan's future, but if he regains velocity and maintains his control, Beavan should be better than Randy Johnson with Sandy Koufax’s control and Roger Clemens' trainer.
