KBO DFS: The Argument for the SK Stack

Unfortunately, we don’t have platoon stats for the KBO, but we do have years of baseball logic that says right-handed hitting excels more versus left-handed pitching than any of the other three combinations. The SK Wyverns have two of the best right-handed power bats in The O and are facing a bad left-handed pitcher on the Saturday 1 a.m. EST baseball slate.

Jeong Choi and Jamie Romak are tied for second in The O with 30 HRs since the start of 2019. Choi is eighth in wRC+ (148) and fifth in ISO (.223) over that span, while projected by ZiPS to be second in HRs (26) for 2020. Romak is 13th in wRC+ (138) and third in ISO (.231), while projected by ZiPS to be third in HRs (25).

These aren’t just two of the best right-handed power bats in The O, but two of the best bats. Period. And they draw a bad left-handed pitcher tonight in Young-gyu Kim of the NC Dinos.

Kim is a spot starter, eighth on the team in starts since 2019. He sports a 5.30 ERA over that 71.1-IP span. How much in bad luck? Not much, as his FIP is a robust 5.17. the big number that we’re looking at when we see a lefty up against SK is Kim’s 1.14 HR/9.

The problem is that these are all on the face and should make SK a chalky play. For one, Choi and Romak are absolutely great cash plays. As for GPPs, we can be contrarian with our third piece on FanDuel. Instead of rostering Dong-min Han, a left-handed hitter who leads the team with four HRs, we can go to another bat with the favorable platoon split: Eui-yoon Jung.

Since 2019, Han has a .267/.372/.420 slash with a .367 wOBA, a .153 ISO, and a 121 wRC+.

Over that span, Jung has a .281/.339/.438 with a .356 wOBA, a .158 ISO, and a 114 wRC+.

There are drastic differences in the two as real baseball players, but for DFS purposes, they’re pretty even, as walks are the big separator that gives Han the overall edge, and cui gives a damn about walks? We’re looking for power, so boosting the power and platoon advantage, we bench the team leader in HRs for the better matchup and maybe catch some differentiation.

The greater way to differentiate is at pitcher or with our second stack. Or all three.

The pitcher spot on our roster is a little hard as the Warwick Saupold, Hyun-jong Yang, and Jake Brigham should all split the chalk. An embarrassment of riches. Going with the most skilled or who you feel will be the lowest-owned is fine.

As for the secondary stack, the Hanwha Eagles face Kyung-eun Noh of the Lotte Giants, who has allowed 1.25 HR/9 since 2018. Hanwha sucks, but they only have four HRs and a team OPS under .700. Excellent regression candidates against this gas can.
