While McKinstry showed some promising contact skills and defensive ability in two seasons at Central Michigan, he didn't hit the ball with much authority or draw a lot of attention as a Draft-eligible sophomore in 2016. After the Dodgers took a 33rd-round flier on him and signed him two days before the deadline for $100,000, he reached Double-A during his first full pro season but began 2018 back in low Class A. He finally broke out last year, hitting .300/.366/.516 with 19 homers between Double-A and Triple-A to claim a spot on the 40-man roster.
McKinstry has grown into solid raw power since adding strength and some loft to his left-handed stroke. Though he has gotten more aggressive at the plate, he still makes regular contact and draws his share of walks. He has solid speed out of the batter's box but it doesn't translate into basestealing prowess.
With his quickness and plus arm strength, McKinstry is a quality defender at second base (his primary position), similar if a bit more erratic at third base and capable at shortstop. He also saw brief action at all three outfield spots last season. His combination of offensive ability and versatility could make him a lefty-hitting version of Chris Taylor.
