Build: thick throughout frame, especially midsection/quads -- legs; broad shoulders with wide hips; power bottom; body will be high maintenance going forward; could use some conditioning.
Mechanics: 3/4 arm slot; good tempo but can rush; drop and drive type; arm stab in back and back elbow can get high; front side glove gets high and big; has slight inverted W; starts from 1B side of mound but foot landing is on 3B side; crossfire delivery; cuts hips off when rotating; gets over front knee when releasing; can land stiff on front when throwing offspeed; high effort delivery but can repeat well presently; huge innings-eater type body, do not have questions about durability.
Presently plus velocity; command is well below average, has trouble controlling the zone; small arm-side life; 2-seam 91-92; create low amount of swings and misses; presently plays down but could play to 70 grade with improved command and possible velocity jump in bullpen.
Arm-side sinking action; slowed arm speed in lower velocity band; consistent arm speed in higher velocity band with more sinking action; created more swings and misses in higher velocity band; presently below average but could play to average with improved command and higher spike in velocity from fastball -- comfortable arm speed/separation from fastball velocity.
Presently caught in between breaking balls; sweeping type break; flashed some bite; presently throws slider in curveball velocity band; slows arm speed and pronates wrist out in front; presently does not throw for a strike; at times loses grip and spin one but doesn't break; in higher velocity band did show ability to spin it; presently well below average but with improved command and velocity spike could show sharper shape and bite.
Tyler Kolek is a big, Texas right handed pitcher who had a body of an innings-eater horse and arsenal of a mid-rotation starter. His complete arsenal flashed at least average and he currently throws his fastball in plus to double-plus velocity band. Kolek has a bit of an arm stab and can cut himself off in his delivery but he repeats relatively well despite having a high effort delivery. Kolek would need to make the necessary adjustments to improve his command and let his full arsenal play to its' full potential for him to remain a starter but signs point to him being a reliever.
Round Drafted: 2014 1st round, 2nd overall
Why: Big Texas Prep RHP; showed ability to spin a breaking ball and ability to replicate arm speed on sinking action changeup; trust their developmental staff to tweak his delivery and improve command to keep him a starter -- bullpen velocity spike, improved command could allow Kolek to become a closer.
