Diaz actually played in the Under Armour All-American Game at Wrigley Field last August, going 1-for-3 against many players who are older and were drafted in last month's draft. As the DH, he batted 7th in a lineup that included new Twin Brian Navaretto.
Diaz checked into the game at 6' 3", 195 pounds. Baseball Factory said this about him:
Over the last 11 months, however, opinions of Diaz, who was once considered one of the top prospect in this year's market have begin to differ.
So what's changed?
The now 16-year-old began to fill out. He's now an inch taller (6' 4") and heavier (210). After being considered an "OF", he's now considered a "1B/OF" with the likelihood being that his future home is first base. Diaz has an above-average arm, so there is some feeling that the Twins will allow him the chance to play right field (you know, because they don't have any outfield prospects).
The Twins have been enamored with Diaz for quite some time and, scouts believe, paid considerably more for his services than any other team would have. Baseball America had this nugget in their June 26 notebook:
The joke many Twins fans will make is that despite Diaz showing huge power in BP, he "turns into a singles hitter in games." Scouting comparisons have included David Ortiz and Ryan Howard, both similar in body-type and left-handed power bats.
As with every 16-year-old IFA signing, Diaz is ineligible to play this season. The Twins may be aggressive with him - as they were last year with Amaurys Minier - and have him participate in Fall Instructs. That would likely lead the way towards skipping the DSL and making his pro debut next June in the GCL.
More to come...
