03/13/2011 - College PREP - Greenville, SC McKinnon is a young (2013) 3B with a solid, average frame that shows projection as he continues to physically mature. Foot speed is average as indicated by his 7.57 60 time. He will benefit by getting on a speed / agility program to improve foot quickness for the next level. Feet are active and aggressive as he moves well laterally but needs to play through routine ground balls more with his body. Glove action is presented out front, displaying soft, clean, and sure hands. Throws are accurate but must get on a long toss program to build more arm strength with carry. Offensively, Martin shows a balanced setup and approach. Hands are quick, flashing bat speed as he shows a feel for the barrel with ball jumping off when centered. He has strength in his swing with hitting grades improving as he works to keep hands / barrel through the baseball at contact. With 2 years to further develop, McKinnon has a lot of potential with the makings to be a solid player as he continues to improve.
