Preliminary rosters were announced Thursday afternoon for the 2018 Arizona Fall League and four Marlins prospects are included.
Outfielder Monte Harrison has spent this entire regular season with Double-A Jacksonville, slashing .243/.317/.408 with 19 HR. He’s had severe swing-and-miss issues, but still ranks as the organization’s No. 1 prospect, according to MLB Pipeline. Harrison is no stranger to this prestigious circuit of elite young talent.
Jacksonville teammate Brian Miller leads all Marlins farmhands with 37 stolen bases in 2018. The 23-year-old owns a .293/.335/.355 line overall, though his production has waned since the promotion from Jupiter.
