Mariners 10 Round MLB Mock Draft

With the 90th Pick of the 2018 MLB Draft, the Seattle Mariners Select:

Like Kowar, we have written about McKenna in our draft prep series. Hailing from the same program as Mitch Haniger, McKenna gives the Mariners farm system another solid OF prospect with a decent upside.

The hit tool will have to carry him to the big leagues, but it has every chance to do just that. McKenna has a good swing, and some believe that more power could be on the way. He was able to raise his slugging percentage in all 3 seasons at Cal Poly. He shows good gap-to-gap power and could hit 15 homers as he continues to develop.

Defensively, he is probably destined for LF, despite playing a nice CF for most of his college career. He lacks the speed to stick in CF, and his routes and jumps aren’t crisp enough to compensate. He should be a good defender in left, where is below-average arm can be hidden a bit.

The most likely scenario for McKenna is as a platoon outfielder or solid 4th guy. While not exciting, for a 3rd round pick, this is a good return on investment.

The Mariners will love his advanced approach, and his bat speed is a good indicator of power to come. While not an elite prospect, with the 90th pick, McKenna gives you a nice blend of floor and ceiling.
