Prospect Profiles: Seattle Mariners



A look at the farm system of the Seattle Mariners

The 2016 season for the Seattle Mariners was a competitive season filled with promise, but with their 86-76 record ultimately landed them two games behind in the wild card standings. This off-season their focus was to add pitching and some infield help. They traded for Jean Segura, Danny Valencia, Yovanni Gallardo Drew Smyly. The Mariners are hoping that these moves put them into the playoffs for the first time since 2001. If that doesn’t work out, maybe some in their farm system could be of assistance. Below we’ll be taking a closer look at some of the top players in the Seattle Mariners farm system.

Tyler O’Neill OF

Tyler O’Neill was drafted by the Seattle Mariners in the 3rd round of the 2013 June Amateur Draft. The Canadian native started out as a catcher in high school and moved out to the outfield over the last few years. Last season, O’Neill hit .293/.374/.508 through 130 games at Double-A. His 492 plate appearances consisted of 24 home runs, 26 doubles, 62 walks, a whopping 150 strikeouts while driving in 102 runs. His power ability could just be enough to gain him an everyday role in the near future with his solid fielding. Seattle will be looking for him to cut down on the strikeouts as well.

ETA: Late 2017

Kyle Lewis, OF

Kyle Lewis was drafted by the Seattle Mariners with the 11th overall pick in the 2016 June Amateur Draft out of Mercer University. Lewis had a very successful 2016 Junior year in which he posted a .395 average while hitting 20 home runs and driving in 72 Mercer hitters in 223 at-bats. After the draft, he joined the Everett AquaSox, he got his professional career rolling. He hit .299/.385/.530 with 3 home runs, 5 triples, and 26 runs through 30 games. His season was ultimately cut short after a serious knee injury. It likely will hurt his center field chance due to possible loss of speed, but despite this his plate discipline and above average plate speed could just be enough to stay in the future lineups.

ETA: Late 2018

Max Povse, RHP

Max Povse was originally drafted in the 42nd round of the 2011 June Amateur Draft out of high school by the Los Angeles Dodgers. He chose to go college and was a last drafted in the 3rd round of the 2014 June Amateur Draft out of the University of North Carolina at Greensboro by the Atlanta Braves. Povse was acquired by the Mariners in a November trade. He is a tall, lengthy pitcher with a an “above average” fastball that reaches 91-95. Last season between High A and Double A, Povse went 9-6 with a 3.35 earned run average and 139 strikeouts through 158 innings. With his pitch selection, Povse has ton to work with and could be expected to pitch in Seattle very soon especially if their free agents do not pan out.

ETA: 2017

Andrew Moore, RHP

Andrew Moore was drafted by Seattle in the 2nd round of the 2015 June Amateur Draft out of Oregon State. Moore has a fastball that often reaches 93 but averages out at 91. He uses a curve ball, change-up, and slider help get him out despite just be a little above average. Last season between High A and Double A, Moore went 12-4 with a 2.65 ERA and 133 strikeouts over the course of 163 innings.

ETA: 2018

Nick Neidert, RHP

Nick Neidert was drafted by Seattle in the 2nd round of the 2015 June Amateur Draft out of high school. His fastball is between 80-94 mph and compliments that with his curve, slider, and change. They all could all use some minor adjustment, but gives him a strong base for improvement. He spent last season with the Clinton Lumberkings going 7-3 with a 2.57 ERA and 69 strikeouts through 91 innings. Scout who’ve watched Neidert see potential as long as his other pitch selections develop.

ETA: Late 2019/2020

Dan Vogelbach, 1B/DH

Dan Vogelbach was acquired by Seattle at the trade deadline this past June after originally being drafted by the Chicago Cubs in the 2nd round of the 2011 June Amateur Draft. He went 1-12 in his short stint in the majors but has shown a lot of promise throughout his 2016 minor league season. Vogelbach hit .292/.417/.504 with 23 home runs, 25 doubles, 96 RBIs, and 96 walks through 459 at-bats. He has plenty of upside at the plate with his strike zone awareness despite his 102 strikeouts. He currenlty plays first base, but with his limited range don’t be surprised to see him as an designated hitter during his career.

ETA: 2017

Mitch Haniger, OF

Mitch Haniger  was drafted by the Milwaukee Brewers in the 1st round (38th pick) of the 2012 amateur draft, then traded to the Arizona Diamondbacks in 2014. He was recently acquired by the Mariners in the same deal that sent them Jean Segura. Last season at 26, Haniger .229/.309/.404 in 109 at-bats. His minor league has been a roller coaster of adventures. He has what some scouts consider average power, speed, and a strong arm. He will typically hit around .260 with plenty of pop off the bat.

ETA: 2017

Brayan Hernandez, OF

Brayan Hernandez signed out of Venezuela in 2014. He is a switch hitting outfielder that spent the last Dominican Summer League and Arizona Rookie League. Hernandez hit .281/.327/.433 with 14 doubles, 4 triples, 6 home runs, and 21 stolen bases through 263 at-bats. His best attribute is his speed which allows him to cover a lot of ground in the outfield as well as swipe some bases. He has shown some signs of some power as well. The Mariners will look for him to become a more patient hitter at the plate while he spends probably the next few seasons in the minors.

ETA: 2021

Drew Jackson, SS

Drew Jackson by the San Francisco Giants in the 37th round of the 2012 MLB June Amateur Draft from Miramonte HS and the Seattle Mariners in the 5th round of the 2015 MLB June Amateur Draft from Stanford University. Jackson hit .258/.332/345 through 524 at-bats. His hitting could use quite a bit of improvement, but scouts really enjoy watching his fielding. Jackson is filled with speed and a strong arm which benefits him at shortstop as long as he minimizes his error percentage. His athleticism makes him a unique player to watch in the field. It will be a few years before we see him in the big leagues though.

ETA: 2019

Just Missed:

Guillermo Heredia, outfielder, did not play in 2016, has a solid hitting approach with speed which help on the defensive end. He does lack power.

Dan Altavilla, RHP, pitched 12 innings in the majors and posted a 0.73 ERA with a walk and a strikeout.


The Seattle Mariners are a very explosive team filled with talent up down their roster. Last season, they just missed the playoffs and are hoping to get there this season. The Mariners addressed their need going into the off season with some trades and free agent signing. If those do not work out, Seattle will look to their farm system to fill their needs when necessary.
