Obviously, Kopech is known for flashing an absolute heater at 105mph fastball, but most of the time he lives in the low 100s and upper 90s. Further improving his arsenal, he tosses a heavy 12-6 with great action. That being said, Kopech and the training staff feels that he has room to fill out. At 6’3” and 205lbs, he probably has room on him for another 20lbs of muscle. Now, if he’s already throwing in the low to mid 100s, imagine the velocity if he puts on more weight. We could be looking at a record setting fastball, potentially being able to sit 103-104 and occasionally flash something 106-107. This is all just conjecture, but don’t call me crazy because this is a definite possibility that the world needs to prepare for. That being said, the name of the game is control, and if he can continue to throw high heat with control, then I’d say he’ll be ready to become a closer for the Sox during the post Kimbrel era.
All in all, Kopech could be a great future closer, as I feel his talents could be used most effectively as a come in and shutdown type of pitcher. However, we will see what the coaching staff does with him, as he continues to perform well at the Advanced A level.
