MLB DFS Picks Today (8/19): The Padres Stack Is The Play

Fernando Tatis Jr. — one of the featured players on today's slate.

The Quick Answer

Wednesday's early four-game slate does not hand you a pitcher worth paying up for. Paul Skenes (PIT) is still the top-projected arm at $9,500, but his fastball has lost more than a full tick since last season and the Stokastic Sims are already building him well under his 53% ownership. The clean, repeatable edge sits on the hitting side: the San Diego Padres, led by Fernando Tatis Jr. and Jake Cronenworth, carry the highest stack score on the slate and a full re-run pushes the field toward roughly 60% exposure to them. The full pitcher tiers, the Padres pricing math and the two pitchers the Sims are quietly fading are below.

A Four-Game Slate Where The Stack Beats The Arm

Start with the thesis, because everything below traces back to it: on a four-game early slate, this is a hitting-driven build, not a pitching-driven one. Every arm on the board carries a real question mark, and the show said as much before diving into a single strikeout prop. That reframes the build order. On a normal night you lock a pitcher first and fill around him. Here, the Stokastic MLB Data Hub points the other way: the top-stacks tool has one team clearly ahead of the field, while the pitcher pool splits five ways with no one arm claiming more than 42% of the Sims. Hold that number, because it explains why the two most-owned pitchers on the slate are also the two the Sims like least.

The Pitching Board: Five Arms, No Clean Smash

Here is the shape of the pool, with the strikeout props that expose how thin the ceiling case is across the board.

The row worth sitting with is the top one. Skenes at 53% ownership is a lot of the field on a four-game board, and a full-slate Sims re-run still has him roughly 16-to-20 points under that number, somewhere in the mid-30s to low-40s percent of lineups. That gap between what the field is doing and what the Sims are doing is the whole story of this pitching pool, and it starts with why Skenes looks different than the pitcher who dominated the league a year ago.

Paul Skenes Still Looks Like Paul Skenes On The Price Tag. The Fastball Says Otherwise

Skenes at $9,500 is priced like a steal relative to where he sat for most of last year, and on paper the matchup helps: Detroit carries a 3.9 implied team total, tied for the lowest on the board, and he is pitching at home. But the fastball tells a different story than the salary. He sat 99 mph in 2024 and 98 in 2025; this year he is averaging sub-97, and his last start clocked in at 96. That is more than a full tick of velocity gone in two seasons. His last outing against Miami was clean on the surface (five innings, one earned run, four strikeouts, five hits) but he needed only 65 pitches to get through it, which raises the question of whether he is being managed on a shorter leash rather than simply cruising.

The strikeout prop still sits at 5.5-to-6.5 with juice to the over, so the market has not given up on him. But the outs prop lands at 15.5, or five innings, not six-plus, and that combination, diminished stuff plus a shorter workload, is why the Sims keep him well below his ownership share even while still ranking him the top-projected arm. He is not a fade. He is a "take him if you want him, but do not assume the field's 53% means he is a lock" arm, and that distinction matters on a slate this thin.

Clay Holmes Is An Elite Real Pitcher And A Capped Fantasy One

If Skenes is the pitcher the field over-owns relative to his stuff, Clay Holmes (CHC) is the pitcher the Sims fade for the opposite reason: he is genuinely excellent, just not built for DraftKings scoring. At $8,200 against the Chicago White Sox, he is allowing 0.57 home runs per nine this year against a career rate of 0.6, a 4.9% career barrel rate and a 62% ground-ball rate. Those are elite power-suppression numbers, on par with the best pitchers in the league at limiting hard contact.

The problem is strikeouts. Holmes is sitting at a 19% strikeout rate this year and 18% last year, with an 8% swinging-strike rate that lags what a real fantasy anchor needs. His last start against St. Louis shows exactly how the ceiling caps out even in a clean outing: six and two-thirds innings, one hit, one walk, zero earned runs and three strikeouts, good for 24 DraftKing points, a fine score but not a lineup-winner. He does have a path to a bigger night if the strikeouts come, since the White Sox strike out at the fifth-highest clip in baseball on their active roster, a 23.5% rate against right-handers that ranks alongside the Los Angeles Angels, a lineup Stokastic regularly targets for the same reason. But the floor case is limiting runs and picking up a few called strikeouts rather than missing bats, and that is why Holmes lands roughly 20% under his own ownership share in the Sims, the single most negatively leveraged arm on the board.

The Two Arms Getting The Positive Leverage

If Skenes and Holmes are overowned relative to what the Sims want, the exposure has to land somewhere, and it lands on two pitchers in particular.

• Michael King (SD), Vs. Mets. King's strikeout rate has fallen every year since his move to the rotation: 28% in 2024, 25% last year, and just over 21% this season, a career low, alongside a career-high walk rate. That is a real red flag on its own. What makes him playable anyway is the matchup: the Mets rank 28th in wRC+ against right-handers on their active roster, and Juan Soto's stint on the injured list strips out the one hitter who had been reliably productive in that lineup all year. The Sims are building King around 36-to-42% of lineups, several points over his roughly 34% ownership, positive leverage even against a declining strikeout profile.
• Spencer Schwellenbach (ATL), Vs. Minnesota. At $6,500, he is making just his second start back this season, which usually scares a field off. He carries a 21% career strikeout rate and draws a Minnesota lineup that is missing its best version of Byron Buxton, who has been ice-cold since returning from injury even with the Twins largely healthy elsewhere. A full-slate Sims re-run pushed his exposure up to roughly 30%, and even after that bump he still sits a few points over his ownership, making him the clearest cheap-arm leverage play on the board.

That is the pitching pool in one sentence: the field is paying up for the two names it recognizes, Skenes and Holmes, while the Sims quietly route the exposure toward the two arms with the better swinging-strike math against a softer lineup.

Stacking: San Diego Is The Runaway Top Stack

Here is where the four-game format actually helps instead of hurts. The San Diego Padres, taking on Robert Stock and the Mets, post an 18.94 stack score on the Stokastic Data Hub, the highest number on the slate, with a 17.9% top-stack probability against a field that is only giving them 13.8% ownership. That gap between what the tool likes and what the field is paying is exactly the setup for a slate where one stack pulls away, and a full re-run confirmed it: the Sims settled at roughly 60% exposure to San Diego.

The individual pieces back up the team-level signal. Fernando Tatis Jr. is the single most-owned hitter in the entire player pool at 60%. Jake Cronenworth, batting second with the platoon advantage at a flat $3,000 salary, sits at 48% exposure, the highest number among any hitter not named Tatis. Manny Machado in the three-hole and Jackson Merrill round out the priciest tier of the stack, both drawing heavy run as well. On the pitching side of that same game, Robert Stock is one of the arms the Mets are trotting out, and the Padres' own team total sits toward the top of a bunched four-game board where every implied total lands within a run of the next.

The natural follow-up is whether 60% is too much of one team, and the honest answer is that it depends on your entry count. If you are building a small number of lineups, an exposure cap inside the Data Hub's stacking tool can trim that down. But for a large-field, high-volume build, the gap between a 17.9% top-stack probability and 13.8% field ownership is the definition of a stack you want to lean into rather than fade off of, and it is the one part of this slate with no real argument on the other side.

Where The Field Is Light: Pittsburgh, Detroit, Minnesota, The Cubs-White Sox Game

The flip side of a 60% commitment to one team is that several other lineups get almost nothing. The Sims are running noticeably underweight on Pittsburgh, Minnesota, the Chicago Cubs and the Chicago White Sox, the exact game the show is treating as a bullpen-adjacent afterthought at Wrigley Field, where the weather (73 degrees, wind blowing in) is close to neutral for power today. A modest re-run did pull in a bit more exposure toward Pittsburgh and Detroit as the day went on, roughly 17% Detroit against Skenes and a bump for Atlanta against Bradley, but even after that adjustment, the field simply is not spreading itself evenly across four games. That imbalance is worth knowing if you are building a large number of lineups and want a genuine second stack rather than pure chalk-plus-darts: Detroit against Skenes, given his diminished stuff, and Atlanta against Taj Bradley both carry more life than their exposure numbers suggest.

A Worked Example: Building Around The Padres On A Thin Pitching Slate

The show ran this logic live, and it is a clean template for anyone building today:

1. Anchor the lineup with San Diego bats first, pitcher second. Start with two or three of Tatis, Cronenworth, Machado and Merrill before locking a pitcher. On a four-game slate with no clean pitching smash, the stack is the more reliable foundation.
2. Pick your pitcher lane, not just the highest-owned name. If you want the field's chalk, Skenes is still the top-projected arm, but know you are paying for stuff that has visibly regressed. If you want leverage, Schwellenbach at $6,500 or King against a diminished Mets lineup both carry positive exposure relative to ownership.
3. Fade Clay Holmes unless you specifically need the floor. He is a legitimately good pitcher, but his strikeout ceiling is capped enough that the Sims are 20% under the field on him. That is exactly the kind of real-pitcher-versus-fantasy-pitcher gap worth knowing before you lock him into a cash lineup expecting upside.
4. Use the secondary game for differentiation. Detroit against Skenes and Atlanta against Bradley both carry more juice than their current ownership, useful if your Padres exposure is already high across your entries.

That four-step sequence is the difference between defaulting to the highest-owned pitcher name and actually building off what the Sims are telling you. Lean on correlation strategy as you construct the Padres stack, keep your options flexible with late swap, and if the vocabulary above is new to you, the how to win at MLB DFS primer and the MLB DFS glossary cover it.

The Bottom Line

Zoom back out and the day resolves cleanly. This is a slate where the arms all carry real question marks, from Skenes' diminished velocity to Holmes' capped strikeout ceiling to King's declining K-rate, so the pitching decision becomes about which flaw you are comfortable paying for rather than which arm is flawless. The hitting side has no such ambiguity: San Diego is the highest stack score on the board, underowned relative to that score, and the field is already leaning toward roughly 60% exposure. Build the lineup around the Padres, then pick your pitching lane, chalk with Skenes or leverage with Schwellenbach and King, based on how much of the field you want to be.
