Bowman's stuff doesn't blow you away but it's nothing to scoff at. His fastball sits 88-89mph touching as high as 91mph. That's average velocity but the pitch plays down a bit due to how straight it is both vertically and horizontally. Bowman is already at a disadvantage due to his height. He's not going to get natural downhill plane on his fastball. At the next level he's going to have to find a way to make the heater wiggle or sink.
Bowman features three secondary offerings; a changeup, curveball and slider. Of the three, he worked most often with a low-70s curve which suited him just fine against Ivy League hitters but likely won't garner swings and misses from professionals. It has decent depth but its break isn't sharp. The slider shows much more potential. It was inconsistent but flashed nasty, two-plane movement here and there. Scouts nearby mentioned their desire for him to use it more often. Bowman's most consistent offspeed pitch was his changeup which sat in the upper 70s. It showed promising fade and run but Bowman noticeably decelerates his arm.
Other ancillary stuff you might want to know about Bowman:
He obviously fields his position well since, when he's not pitching, he's playing shortstop.
He holds runners well. I timed him in the 1.25-1.35 second range from the stretch. He varies the height of his leg kick from the stretch as well, to screw with baserunners and the timing of the hitter.
Bowman is a slightly below average runner, timed at 4.35 seconds from the right side from home to first.
He is adequate at shortstop, not spectacular, and I'm bearish on his ability to hit at the next level.
Other note: Bowman's teammate Sam Mulroy is a pretty interesting prospect in his own right. He's an above average runner who plays center field, third base and catches. It takes a few trips to properly scout a swiss army knife like Mulroy. I'd like to see him again if I can, but the drive may prevent me from doing so.
