|Severino’s reputation as a defensive standout remains intact, with
some folks attributing it to the Nationals decision to place him on
the 40-man well before the Rule 5 deadline. The bat? Well, as you
might have guessed, it’s still well behind the glove. His slugging
percentage dipped from 2014 to 215 (.399 to .331), and his average
remains in the .245 range. He neither walks nor strikes out much,
so the hope is that he’ll develop both patience and power in 2016.
|With Wilson Ramos in his walk year, the Nats opted to put Kieboom
on the 40-man roster in 2015 despite having not played above High-A.
Like Severino, his defensive skills are ahead of his offensive skills
and he’s also been given praise for his ability to work with pitchers.
While he doesn’t he strike out much, and walks a fair amount, the
power disappeared in 2015, which is very concerning given that he’s
well past any reasonable attribution to his 2013 TJ surgery.
|The power sapped from ’14 to ’15 (.462 SLG% to .377) and the
sloppy ball-handling returned (22PB, which is significant con-
sidering how minors’ scorekeepers tend to dole out WPs instead)
in his first full-season campaign. He’s likely to start 2016 in
Potomac, where he finished 2015 and in a short stint, did little
to dispel the inference that he’s a hitter in search of a position.
|It’s been five years since Tillero was among the large group of IFAs
trumpeted in the post-Smiley era, so it may seem like the Venezuelan
is older than just-turned-22. It’s a leitmotif, but the Nats are short
on age-appropriate-to-the-level catchers, which is why he makes the
list despite below-average offense (.212 GPA). He did however have
just nine passed balls while throwing out 52% of runners attempting to
steal on him and his pitchers.
