We are less than a month away from the 2019 MLB Draft. The Mariners will be more involved in this draft than normal, having secured an extra pick at the end of the 2nd round in the Carlos Santana for Edwin Encarnacion trade.
This will also be the Mariners first draft in their “re-imagining” of their entire organization. While these names won’t help Seattle right away, they can add more depth and impact to their farm system, which makes trading prospects easier and increasing their margin of error.
Seattle have picks 20, 59,76, and 97 this year, giving them a great opportunity to add significant talent to their farm system. In our first mock draft, which you can read here, we focused on a straight draft strategy instead of trying to work their bonus pool to manipulate the draft board. We will do the same here.
With all that in mind, let’s get started with the 20th overall pick in the 2019 MLB Mock Draft.
Pick 20: Mariners select Braden Shewmake, SS Texas A&M
With the first pick of their draft, the Seattle Mariners stick to their status quo and select a relatively safe college player in round 1. In Dipoto’s first 3 drafts he selected similar players Kyle Lewis, Evan White, and Logan Gilbert.
Shewmake, a junior shortstop at Texas A&M, has a slender frame, standing at 6’4″, 190 lbs. He has a simple, compact swing that produces a lot of line drives. Ever since he got to College Station, Shewmake has produced. He doesn’t strike out and has a prototypical “control the zone” approach.
Shewmake has shown power in the past, hitting 12 home runs as a freshman. But he has hit just 5 home runs in each of the past 2 seasons. He makes a lot of contact and should hit for a high average with 10-15 home run power to boot.
Defensively, he has a chance to stick at shortstop. He has a strong, accurate arm and can make all the routine plays. His ultimate landing spot might be second base, but his bat profiles well at either spot.
He doesn’t have plus speed but has good instincts and can steal bases at a good rate. Overall, Shewmake should be a .280/.350/.400 hitter with 10-15 homers and stolen bases, as well as average or better defense up the middle.
