The weird part is why Hahn still gave in on the trade after pushback from Paddy and Tatis, Jr.
The biggest thing with kids at ages 14-17 is projection.
They were warned by Tatis’ father that he was still not done growing...maybe they assumed that meant he would lose speed instead of gaining it and have to be moved off of SS to another position. Of course, one could argue that his light power at the time would only increase with more height/bigger frame and adding muscle...which is usually the case when still physically maturing kids hit stateside.
He’s now one of the arguably 3-5 fastest base runners in MLB at 6’3 1/2” and got his 13th steal on what amounted to a pitchout to Buster Posey last night. He has now also scored twice from third on short pop ups to 2B...the most recent infielder was so rattled that the throw wasn’t even close. Not to mention scoring all the way from second on an out recorded at 1B and the LUIS Robert highlight of scoring from SECOND on a deep outfield flyout.
He also had to at the very least have possessed above average arm strength, because he has made 360 degree throws from SS to first in the last week at 93.7 and 94.0, the two hardest of any SS in MLB this year. In fact, if you want to pick on one of his bad habits, it’s now waiting a beat or two long like Shawon Dunston used to do in order to make the out at first more dramatic/highlight reel-worthy.
So you had a still-growing SS who already flashed the three most important qualities of a quality up the middle player...speed, throwing arm and raw fielding ability. To trade that player at age 17 before you discover what you really have, knowing his bloodlines, and knowing one of the most knowledgeable GMs about Latin American talent is already insisting on that specific player...well, it should have sent up alarm bells up and down every level of the organization that they were in the process of being outscouted on their own player and that Paddy’s original scouting assessment on Tatis was being overrun by the immediacy of trying to compete in 2016 with half a roster and a foundering manager.
