KBO DFS: The Argument for Stacking SK Wyverns
The SK Wyverns have been terrible this season.
They’re only two wins out of last place at 14-33, 0.23 out of last at only 3.77 runs per game, and .024 points out of last with a .671 OPS. Hanwha is the WOAT, but SK has been close.
SK hasn’t received the same targeting by DFS players for a few reasons, though. First and foremost, there is talent there, making room for regression toward the mean. Second, they are only slightly below average in Ks with 340. Third, they’re tied for third in the league with 158 BB, leaving the fourth reason that their .345 OBP is right in line with the .343 league average.
A lot of SK’s offense troubles revolve around underperforming hitters, which is different from Hanwha’s troubles. Hanwha’s troubles revolve around bad talent. SK’s around bad slumps. In SK, there is room for growth.
Facing a pitcher with a propensity for coughing up the long ball could be some chicken soup for the slumping soul. Tonight, SK faces that guy in LHP Chae-heung Choi
Choi is a good pitcher, but not a very, very good pitcher. Sure, he has a solid 7.31 K/9 and 9.9% K-BB% since 2019, but his 4.33 FIP displays some vulnerability, which is displayed in his 4.19 BB/9 and 1.16 HR/9 this season.
He isn’t the perfect candidate to cure what ails SK, but he’s what we got now and there is serious leverage to be had. Choi may actually be modestly owned as an SP2 on Tuesday morning’s slate and the rest of the field may just be avoiding the game altogether.
There is talent to target on SK, when we expand our scope beyond this season into past seasons. Looking at how some hitters in this projected lineup have fared against LHPs since 2018 gives us a window into what we’re playing with here:
Jeong Choi, 3B/SS and Jamie Romak, 1B/OF — Everything starts with Choi and Romak when stacking SK. The righty slugger has some serious history of lefty mashing. Since 2018, he has a 1.002 OPS with 19 HRs in 270 PAs against LHPs. Romak, a .995 OPS with 24 HRs in 298 PAs. Neither have hit .300, but both are slugging out of this world. .580 and .611, respectively for the three- and four-hitters.
Kang-min Kim, OF — Kim is only $3,300 on DK and $7 on FD. This is low for a mediocre player, let alone a bat with an .842 OPS, 11 HRs, and eight doubles in 230 PAs against LHPs since 2018. Hits sixth. We can live with that.
Ji-hoon Choi, OF — For $2,800 on DK and $5 on FD, we can have this rookie LHB who’s hitting .330 overall in the two-hole. Not a significant sample, but 11-for-21 against LHPs might affirm that this is just a good hitter. No HR-power at all, but three doubles and a triple of those 11 hits.
Eui-Yoon Jeong, OF— This 33-year-old is on the wrong side of his career, but he is a RHB with some power. Since 2018, he’s slashing .330/.381/.535 against LHPs with 13 HRs. He usually gets the start at DH against LHPs, but keep an eye out for lineups, as he isn’t an everyday player. If you’re still not intrigued by this stack, he’s $2,700 on DK and $7 on FD.
Jae-won Lee, C — .820 OPS versus LHPs at catcher, but he ain’t cheap. $4,700 on DK. Only $6 on FD, but we shouldn’t need to go here. With money leftover, he’s a solid spend-up. No one should have him in their core at that price.
That’s it. That’s the stack.
There are tons of ways to go here. Three-man for FD or DK, Five-man for DK. There is a lot of risk attached, but we’re also not paying anything to take this risk.
If we play three lineups, it’s just fine to have SK in two, if not all three.
— LG is in a similar spot as SK. High power, facing a pitcher with ownership but has a HR problem.
— Not loving spending up or down at SP.
— Great slate to go with a five-man stack and one-offs because three of the four best stacks—SK, LG, and Kia—are really cheap and without a must-play SP in the $9ks, we can play whomever we want.
— That said, not a bad slate to leave about $1,200 on the table doublestacking if it comes down to it.
