The Mariners usually don’t have many prospects make it to the major leagues. In many cases they are traded or aren’t good enough to make it. Kyle Seager and Edwin Diaz are among the few that have made it to the major leagues along with staying with the Mariners.
#1 Kyle Lewis outfielder: Mariners #1 pick in 2016. Has had trouble staying healthy since being drafted by the Mariners. Even so he is still considered their number one prospect. He started his season with single A Modesto where he played in 49 games with a .260 batting average. He had only five home runs so I wouldn’t consider him a power hitter at this time. The Mariners moved him to double A Arkansas where he played in 37 games only batting .220. Positive side he did have an on base percentage over .300 in his career. I expect the Mariners will start Lewis off in double A in 2019. Stay healthy he could end up in Tacoma before the season over. Depending on his play could make the majors in 2020.
#2 Evan White 1st baseman: Another number one pick being selected by the Mariners in 2017. Played 14 games in 2017 at rookie club in Everett. He batted .277 for Everett. In 2019 he had a solid season playing at Modesto as well where he batted .303 with 11 home runs. I wouldn’t consider him a power hitter like you would generally find at first base but he did have 27 doubles at the same time drove in 66 runs. He played a few games with Tacoma however I see him starting next season with double A Arkansas too. He won a minor league gold glove as well. He doesn’t have a lot of speed but he could end up playing some outfield for the Mariners. Might see him in a Mariner uniform in 2020.
#3 Logan Gilbert: Also a number one draft pick this year. Didn’t pitch at all this summer because of mono. Coming out after three years pitching in college he probably will start at high A and possibly end the season in Double A in 2019. I wouldn’t see him most likely until 2021 though we could see him in the second half of 2020 if necessary.
#4 Julio Rodriguez outfielder: international signing from the Dominican Republic. He is only seventeen. He played on the Mariners Dominican summer league team. He batted a solid .315 in 59 games. Might play another year in the DSL before moving through the Mariner minor league system. Be heralded as a number 4 prospect could move up quickly and be on the Mariners roster at a young age. Remember Felix Hernandez made his debut at 19.
#5 Braden Bishop outfielder: drafted in the 3rd round in 2015 by the Seattle Mariners out of University of Washington. He has moved up far as a prospect for the Mariners. This year he was having a fine season in double A before fracturing his forearm in July that cost him the rest of the season. I thought he was going to be promoted to triple A Tacoma in the second half before the injury. He was batting .284 in 84 games before the injury. Most likely start 2019 in double A however could move up to triple A Tacoma if he is playing well once again. He could end up in Seattle in 2020.
#6 Sam Carlson pitcher: 2nd round draft pick in 2017 pitched only two games in games 2017 in the Arizona rookie league. He missed this past year because he had to undergo Tommy John surgery so he missed this season and possibly 2019. He turns 20 in December so he still has a future we hope. Other pitchers have made comebacks and they aren’t as young as he is. Most likely when he returns will start in the low A league.
#7 Josh Sowers outfield: 2nd round draft pick 2018. Had an outstanding first year in professional ball. He had a batting average of .260 in 58 games at rookie Everett. At this point he isn’t considered a home run hitter however he did steal 20 bases so he does have speed. He could start 2019 in High A then move up to double A. He played college ball at Louisville so he move up quickly could see him in the majors in either the 2020 or 2021 season. He and Kyle Lewis could be part of a good Mariner outfield in the future
#8 Matthew Festa pitcher: 7th round pick in 2016. Has been moving up fast in the Mariner system working out of the bullpen. He spent most of 2018 in double A Arkansas. He is another young pitcher with a strong arm throwing around one hundred miles an hour. He could become a good setup man in the Mariner bullpen and was named Mariner minor league pitcher of the year in 2018. He pitched in 44 games at Arkansas with 20 saves and an era of .276. Pitching 49 innings he struck out 67 batters and walked on 12. He pitched in eight games for the Mariners with an era of 2.16. Whether he makes the Mariner bullpen starting 2019 or not he likely will be in the bullpen at some point. He could start the season at triple A if he doesn’t make the Mariner bullpen.
#9 Wyatt Mills pitcher: 3rd round draft pick in 2017 out of Gonzaga. Started in professional career in 2017 at Everett than moved to class A Clinton. He pitched most of 2018 at High A Modesto where he saved 11 games in 35 games with 1.91 era and 49 strikeouts. He walked 13 batter and only gave up one home run. August 1 he moved up to double A where he pitched in nine games however had a high era. Most likely he will start 2019 at Arkansas.
#10 Noelvi Marte shortstop: signed this year by the Mariners as an international player out of the Dominican Republic. He is 17 years old with power and a good arm. Time will tell if he stays at shortstop. There is a possibility he could move to third base. I expect Noelvi will play next year his first in the mariner minor leagues in the Dominican summer league team. The Mainer will give him time to make it to the major leagues. It will be interesting to see where he stands among the Mariner top prospects over the next few years. This will go for the other prospects as well. The odds are high for any player but these are better for these because the Mariners will give them every opportunity to make it.
