CHARLESTON, W.Va. -- It's perfectly OK, for now at least, that Tyler Glasnow is a bit unpredictable, that he may overpower hitters on occasion and then struggle to find the plate.
He's a 19-year-old Power right-hander, a raw talent who touched 97 mph on the radar gun Sunday and generally throws in the mid-90s. As such, he needs time to find consistency.
This season, he's proving the adage that a Class A pitching prospect is much better served by flashing occasional brilliance, even with failures mixed in, than offering a steady diet of fair to middlin'.
"This guy at times is electrifying,'' said Power pitching coach Jeff Johnson. "He shows you what it eventually could be. So it's exciting.''
The 6-foot-7, 213-pound Glasnow overpowered the Hagerstown Suns for most of his 42/3 innings of work Sunday afternoon at Appalachian Power Park, striking out six of the first eight batters he faced, but the Suns rallied for four runs in the sixth against the Power bullpen for a 4-1 victory.
The California native, Pittsburgh's fifth-round draft pick in 2011, allowed just three hits - two in the infield - and no runs and struck out eight in dropping his earned run average to 2.92. He didn't walk a batter through three innings, thereby avoiding his season-long nemesis, but walked two in the fourth and another in the fifth.
Citing the bases on balls, Glasnow did not sound entirely pleased.
"It was OK on paper,'' he said. "It wasn't bad by any means, but for the things I was working on, it wasn't the greatest. It kind of got away from me in the fourth and fifth innings. I walked a few guys. Command definitely got away from me. In the fourth and fifth, I just seemed to lose a little bit.''
His objectives, he said, are "just getting ahead of batters and really commanding the zone. I'm not really going out there to try to strike people out.''
An off-speed pitch always helps. "My changeup has been getting better,'' he added. "That's been a goal of mine, and I've been throwing that a lot more for strikes.''
