SSS rank among all left-handed starting pitchers in the system: 1
When Medeiros finished his senior season with Waiakea H.S. (Hilo, Hawaii) with a 1.12 ERA, .178 OBA, and 16.7 K/9, PerfectGame ranked him as the sixth-best prep prospect available in the 2014 draft. Thus, it was no surprise when the Milwaukee Brewers selected him with their first round pick (12th overall). After receiving a $2.5 million signing bonus, Medeiros struggled with the AZL Brewers to the tune of a 7.13 ERA and 2.09 WHIP.
The following year, Medeiros bounced back somewhat with the Brewers’ A-affiliate Wisconsin, where he posted a 4.44 ERA and 1.28 WHIP in 93 1⁄3 innings, allowing 79 hits (.228 OBA) and 40 walks (10.0%) and striking out 94 (23.5%). However, he slid back in 2016 and 2017 for the Brewers’ A+ affiliates in Brevard County and Carolina, where in a combined 213 1⁄3 innings, Medeiros posted a 5.36 ERA, 1.56 WHIP, .266 OBA, 11.9 BB%, and 19.9 K%.
In 20 outings (15 starts) for Double-A Biloxi in 2018, Medeiros was enjoying his best minor league season to date — a 3.14 ERA and 1.31 WHIP over 103 1⁄3 innings, allowing just 90 hits (.234 OBA) and 45 walks (10.1%) while striking out 107 (24.0%). On July 26, Medeiros was traded along with right-handed pitcher Wilber Perez to the White Sox for closer Joakim Soria. After the trade, Medeiros struggled a bit in seven starts totaling 34 1⁄3 innings, posting a 4.98 ERA and 1.54 WHIP while allowing 31 hits (.250 OBA), 22 walks (14.5%) and 34 strikeouts (22.4%).
Medeiros’ fastball maxes out at 95-96 mph, with tailing action. He’s also got a plus slider which has a significant lateral break, and a solid changeup with good sink and fading action. However, he may have a more successful career as a closer for two reasons:
- He’s got a unique arm slot which makes it difficult for lefties to pick up: Lefties hit just .160 against him this year compared to .261 versus righties.
- His control has been totally underwhelming: His career walk percentage in his four years of professional baseball is 11.4.
Medeiros returned to the Birmingham rotation to begin 2019, and it’s been a very rough start: 0-6, with an 6.68 ERA and 2.041 WHIP in seven starts. Control issues are again plaguing him, as he’s thrown 21 walks against 28 Ks in 32 1⁄3 innings. One saving grace is that Medeiros is still about a year-and-a-half years younger than Double-A league average.
