On July 2, 2016 and just more than a month after turning 16, Dominican native Luis Mieses received a signing bonus from the White Sox for $428,000, as part of a large International Signing Day class that included Luis Robert, Lenyn Sosa and Anderson Comas.

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, where 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 was a bit disappointing, although it’s important to remember that Mieses had been more than a year younger than his competition at every level he’d played thus far. He, like nearly every minor leaguer, missed the 2020 season due to the pandemic shutdown.

After getting off to a difficult start with Winston-Salem (.155/.189/.366) in 19 games to begin 2021, Mieses was demoted to Kannapolis, where he performed much better. In 52 games for the Cannon Ballers totaling 203 at-bats, Mieses slashed .305/.347/.463 with 12 doubles, six homers, 41 RBIs, 13 walks (5.8%) and 33 strikeouts (14.7%). He played well enough to merit another trip to Winston-Salem, where he slashed .275/.319/.510 for the final two months of the season.

While he didn’t club many homers for the Dash he did produce more extra-base hits than singles. It’s also encouraging to see Mieses pick up steam, as he was nearly two years younger than his High-A competition. Combined with both teams, Mieses slashed .270/.312/.463 with 31 doubles, three triples, 15 homers, 74 RBIs, 24 walks (5.2%) and 81 strikeouts (17.6%). For the year, he posted a 116 wRC+ for Kannapolis and a 93 wRC+ for Winston-Salem, which wasn’t too bad based on his rough start.

Mieses began 2022 with the Dash, roughly age-appropriate to his league (slightly younger), and took major steps forward. While still not putting the ball over the fence, Mieses upped his OPS by 30 points (.771 OPS) to show he’d mastered High-A. Thus the right fielder became part of the vaunted Project Birmingham at season’s end — and unlike so many others in the organization, didn’t miss a beat with the promotion to Double-A. While a small sample size of 23 games, Mieses raised his batting average and OBP, keeping pace with his modest slugging, to raise his OPS to .777 at a level 2.2 years older.

Expect Mieses, who has worked his way clearly onto the White Sox outfield prospect radar, to begin the season with Birmingham, with an outside shot at time in Charlotte later in 2023.
