Now just in case you were wondering what is on the farm for coming years in the OF, you may be surprised to find that Jack and his minions actually had two very distinct types of OF's he liked. Further, you may surprised at how many OF's the Mariners have in their system that are in the top 30 prospects. Per MLB-com, there are 10.
Power / low contact guys: Alex Jackson, Tyler O'Neill, Gareth Morgan, Austin Wilson, and a few others worth noting like Jabari Henry, Corey Simpson, and Jose Leal if you look real deep. Of course, Jerry has already reduced this group by getting rid of Kivlehan, Lara, Morban, and Blash. It will be interesting IF the new C the Z, contact skills, and proper plans of attack for every at bat will help this group... or will Jerry keep pruning from this list.
Speed / no power CF guys: Luis Liberato, Braden Bishop, Brayan Hernandez, Austin Cousino, and Ian Miller who are in the MLB-Com's top 30, and a couple others who are also talked about Aaron Barbosa, Leon Landry, Burt Reynolds, Estarlyn Morales, and then the new guys Boog Powell, Daniel Robertson and Mike Baxter. This group should have a leg up, as many in this group already seem to have OK K/BB ratios, but gains here could really make a big difference.
The only ones that kind of find a third type would be Stefen Romero and Dario Pizzano - guys who can hit for average and medium power. Both of these guys already seem to C the Z at the minor league level, but hopefully they can really jump a plateau this year. I would expect that JeDi will be expanding this group in future years.
