Seattle Mariners Top 20 Prospects

2.) Edwin Diaz – RHP

Date of Birth: 3/22/94
Height/Weight: 6’3/165 pounds
Bats/Throws: Right/Right
Acquired: Drafted 3rd round in 2012

Edwin Diaz didn’t project to be anything close to a starter early on his career, but has shown a lot of progress to suggest he could reach that point. Diaz started the season in Advanced A where he was dominant in seven starts, so he was quickly moved up to AA. The lanky right hander wasn’t great there, posting a 4.57 ERA and a 5-10 record but he struck out 103 hitters in 104.1 innings, making for a pretty good K/9 ratio. A big question for the Mariners front office this year is whether Diaz should try and improve in AA or make the jump straight to AAA.

Like Gohara, Diaz’s best pitch right now is his fastball which will touch in the mid 90’s with pretty good command. Diaz also offers a slider which can be a little wild at times, but also can be totally nasty when it’s on. His changeup needs some work, but with time can likely be a good 3rd option after the header and slider. Diaz could afford to get a little stronger, as he only weighs 165 pounds right now, and it’ll probably help out his velocity and his command if he can do so.

    Man that is just the cast with these minor league players. The absolute 5 star can not miss players continue to fall by the wayside.
    How can you tell when a guy who does it all in AAA is going to be a flop?
