Seattle Mariners prospect no. 5 – Brandon Williamson

The Seattle Mariners drafted the tall left-handed pitcher out of TCU in the second round of the 2019 MLB draft, and he has quietly been a really good pick. A lot of the focus has been on pitchers like Logan Gilbert, George Kirby, and Emerson Hancock (for good reason), but many have overlooked Brandon Williamson.

The 23-year-old had a great season with the Aqua Sox in 2019 after being drafted and has picked up where he left off this year. In his first season in the minors, he posted a 2.35 ERA in 10 appearances and struck out 25 batters in 15.1 innings. Not only did he strike out a lot of hitters, but he also walked just five batters and allowed only nine hits.

In 2021, he practically started where he left off and has thrown 12.2 innings in three starts. In those three games, he has allowed four earned runs on seven hits, but the strikeouts are crazy! He has K’d 26 batters in just three short starts…

I think a big reason why Williamson fell under the radar was because of the cancellation of the minor league season. But now that we have a full minor league season to assess Brandon and other minor league players, it gives me a lot of hope about the Seattle Mariners future.

The Mariners have Logan Gilbert, Emerson Hancock, George Kirby, Juan Then, Brandon Williamson, Connor Phillips, Isaiah Campbell, Levi Stoudt, and Adam Macko all in the pitching prospect pool… That’s a lot.

Seattle Mariners prospect no. 6 – Jake Scheiner

Jake Scheiner isn’t a name you are probably too familiar with, but he has been playing some great baseball in Arkansas. Scheiner is a 25-year-old corner infielder (mostly third) who was drafted in the fourth round by the Philadelphia Phillies in 2017.

Scheiner is a product of the University of Houston and joined the Mariners organization in 2019 as part of the return for Jay Bruce. The right-handed hitter has put together a solid minor league career but it hasn’t been anything too special.

But all of a sudden, Scheiner is the best hitter on the Arkansas Travelers with a .358 batting average and 16 RBI. He has also hit four home runs, seven doubles, and walked seven times. I don’t know what the future holds for Jake Scheiner as a non-member of the Top 30 Mariners prospect list.

Maybe he can become an impact player for the Mariners down the line… Maybe he’s next in line to take over the hot corner in T-Mobile Park…
