Luis Palacios is a fantasy baseball SP prospect sleeper and minor leaguer to know. Read our MLB prospects outlooks for fantasy baseball rookies and call-ups.
PROSPECT: Luis Palacios, SP, Miami Marlins
ANALYSIS: Luis Palacios has been with the Marlins organization since signing in 2016. He finally reached complex ball after two seasons in the DSL.
The 6'2" lefty has never had dominant stuff, topping out at around 90 and sitting in the upper 80s with his fastball. His secondary stuff is there, but none has elite swing-and-miss movement. What Palacios does have is incredible elite command of his stuff, walking just 4.2% of hitters he's faced.
The Marlins have bounced the left-hander across three levels this year with mediocre results, allowing 23 home runs over 107 1/3 innings with a 88/24 K/BB ratio. In his most recent start, Palacios was hit hard. However, in his previous two outings, he did not allow a run across 14 innings, with 16 strikeouts and no walks.
VERDICT: When he is on, Palacios is incredibly impressive to watch, but he has such a slim margin of error. No reason to roster him.
