Florial battled with paperwork issues due to his birth certificate and identity, but the Yankees finally made the official signing after Brian Cashman got the go-ahead from Hal Steinbrenner in March 2015.
The Yankees assigned Florial to their Dominican Summer League team to start his career. In 57 games, Florial produced a slash of .313/.394/.527 with 70 hits. The speedy Florial had 11 doubles, eight triples, and seven home runs while driving in 53 runs. He crossed the plate 51 times and stole 15 bases in 20 attempts. His first year in professional baseball shows why the Yankees hung in with his paperwork issues to sign him.
Florial did see a couple of games with the Tampa Yankees of the Florida State League in which he went 1-for-8, the one hit being a single. Florial went back to extended spring training and then settled into the rookie Appalachian League Pulaski Yankees opening day roster.
In 60 games with Pulaski, Florial played mostly center field and put up a slash line of .225/.315/.364. Florial had 53 hits, scored 36 runs while ripping 10 doubles, one triple while smacking seven home runs. He stole 10 bases in 12 attempts.
On September 1, Florial was brought up to the next level with the Charleston RiverDogs of the class low A South Atlantic League. Florial appeared in five games, and 20 at-bats produced a slash of .300/.348/.550. He had six hits, one of which was a triple and another was a home run.
Florial returned to Charleston to start 2107 and started to show what type of player he can become. In 91 games with the RiverDogs, Florial put up a slash of .297/.373/.483 and earned a trip to the MLB Futures game in Miami. He hit 11 home runs while collecting 21 doubles and racing to five triples. He stole 17 bases in 24 attempts.
That performance earned Florial a promotion to the Tampa Yankees on August 1 and kept up his torrid performance at the plate. In 19 games, Florial put up a .303/.368/.461 slash line and collected two more home runs, two doubles, and two triples. He stole six bases in seven attempts with the T-Yanks.
After a breakthrough season, the Yankees sent Florial to the Arizona Fall League to test him against other top prospects. Florial held his own with a slash line of .286/.383/.414 with five doubles and two triples with the Scottsdale Scorpions.
