Just more than a month after turning 16, Dominican native Luis Mieses received a signing bonus from the White Sox on July 2, 2016 for $428,000, as part of a large International Signing Day class that included Josue Guerrero, Lenyn Sosa, Anderson Comas and Kleyder Sanchez among others.
Mieses began professional ball with the DSL squad in 2017, and slashed .263/.302/.320 in 59 games with eight doubles, three triples, 25 RBIs, three stolen bases, 10 walks (3.8%) and 42 strikeouts (16.0%). It was enough to receive a promotion Stateside for 2018, when he slashed .226/.236/.328 in 48 games with the AZL squad with 10 doubles, two triples, two homers, 26 RBIs, three stolen bases, four walks (2.0%) and 35 strikeouts (17.2%).
Mieses’ numbers improved a bit in 2019 with Great Falls, although it could be attributed in part to the thinner air. In 59 games for the Voyagers, he slashed .241/.264/.359 with 14 doubles, four homers, 28 RBIs, seven walks (3.0%) and 46 strikeouts (19.9%). The production has been a bit disappointing, although Mieses has been more than a year younger than his competition at every level he’s played thus far.
In 2019, MLB Pipeline gave him an a 60 grade on his throwing arm, 50 grades for fielding and power, 45 for hit and 40 for running. Pitch selection has been Mieses’ biggest issue, which is evidenced by his extremely low walk numbers.
Mieses really should be promoted to Kannapolis for 2021, as the White Sox would like to see what he can do in full-season play.
