If Segura is for real he's the best player in the deal. Not to say that Walker couldn't become the best or even Marte. As a Mariners fan, I'll take the one that's actually had a 5 win season though. Will Walker ever have one? I still hope so, not hating on him. He's still not a Texas Ranger.
Segura is another Dominican to pal with Cano up the middle. This one absolutely looks like a leadoff hitter.
Aaaannd .290/.370/.490 in 1866 MiL PA from a decently glovey CF (Very glovely corner)? .276/.349/.512 is where O'Neill sits at 1398 PA, 2 promotions behind. .293/.374/.508 this year for Tank if you prefer. Haniger has basically done that, with way less strikeouts (17% of PA), his entire MiL career including .321/.428/.670 in 312 AAA PA. Segura doesn't look like the only heavy lifter coming in on this deal. Dipoto brought in another Tank and this one seems closer to contributing.
Since you spoke of Curtis' stats, here's his Brooks page on his repertoire: His fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has an obvious tail, has some natural sinking action and has essentially average velo. His slider results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Hischange (take this with a grain of salt because he's only thrown 13 of them in 2016) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups.
This could be a bigtime win. I definitely like it.
Now where's the rotation addition we suddenly need?
Happy Thanksgiving!
