Weather to Watch
MIL at CHC | Wrigley Field | Overcast, 77F | Wind: 8.7 mph SSW
Wind blowing out to right at about 9 mph adds roughly 20% to HR carry, and Wrigley is the top weather environment on the slate. Light overcast with 10% precip is a non-issue.
TEX at COL | Coors Field | Light Drizzle, 41F | Wind: 8.6 mph N
This is the only Coors game I will ever talk down. Cold air, wind blowing in from straight center, and a 26% rain chance combine for a 12% HR suppression. The dense, damp air is a real factor on fly ball distance.
BOS at KC | Kauffman Stadium | Clear, 73F | Wind: 22.3 mph SE
The crosswind is the story here. 22 mph from the southeast at one of the bigger outfields in baseball will knock down some balls and push others. Net HR impact is roughly neutral, but ball-in-play noise goes up.
HOU at MIN | Target Field | Overcast, 58F | Wind: 4.9 mph NNW
Cool, damp, overcast, with a 20% precip chance. Slight HR suppression. Worth a check at lock for any movement to the rainout side.
The other five outdoor parks are sitting in neutral wind conditions with negligible HR impact. The Chase Field dome game (ARI vs SF) and the off-slate domes are run-environment neutral.
HR Calls
I am going three different ways on the model board today. One profile stud against a pitcher who has been getting blown up, one environment play at the wind-out park, and one cheap salary that the pricing has not caught up to yet. Two righties, one switch hitter, mix of price tiers.
Byron Buxton (MIN) $6,200 vs Tatsuya Imai
This is the one I keep coming back to. Imai is at 9.24 ERA across 12.2 IP, his vs RHH split is sitting at 11.12 ERA with a .409 wOBA and 20% HR/FB in a small sample, and the peripherals (5.49 xFIP, 21.5% walk rate) say it has not been a fluke. Buxton brings a .276 xISO, 21.1% barrel rate, and a recent form ISO of .444. Target Field plays as an 87 for righty power and the air is going to be cold and damp, so I am paying for the profile and the matchup more than the park. Leadoff with this kind of contact quality against this kind of arm is the play I want at the top of the order.
Ian Happ (CHC) $4,200 vs Brandon Sproat
Three things have to line up for a chalk HR call and they all do here. Sproat is carrying a 5.65 ERA with a 2.20 HR/9 and his split vs LHH is uglier (6.88 ERA, .412 wOBA, 19% HR/FB). Happ from the left side has an 18% barrel rate, a .269 xISO, a .219 form ISO over his last 14 days, and he hits cleanup in the slate's top-implied lineup. Wrigley with wind blowing out to right is exactly the park profile his pull-side flyball swing was built for. DraftKings has not raised the salary even with the obvious setup. The market has not caught up to the matchup yet.
Casey Schmitt (SF) $3,800 vs Zac Gallen
The value piece. Schmitt is a .236 xISO righty with a 15% barrel rate, a 47% pull rate, and a .317 form ISO. Gallen has been getting hit hard by righties in particular this year (.372 wOBA vs RHH, 6.20 ERA vs RHH, 19% HR/FB allowed vs RHH on a 45% hard contact rate). Chase Field is a dome so weather is a non-factor, but the park is a 108 for righty power and Gallen is a fly ball arm getting barreled. At $3,800 batting third on a team that has not gotten any market respect this week, you are not paying anything to take the swing.
Stacks to Target
1. CHC vs Brandon Sproat (R) | Implied Total: 6.24 | ROO Score: 6.6/10
Chalk stack
The Cubs are the highest implied team on the slate by nearly half a run, they are getting Wrigley with the wind blowing out, and Sproat is the most exploitable matchup. The model has the implied total component pinned at the top of the board and the park and weather component is the strongest on the slate. Sproat's vs LHH split is the one to weaponize: 6.88 ERA, .412 wOBA, 19% HR/FB, and a 49% FB rate. Cubs lefty bats vs RHP grade out at a 127 wRC+ with a .354 wOBA and 15% HR/FB on the season, so the profile match is real. Ian Happ (L, 4) and Moises Ballesteros (L, 2) sit at the front of that platoon group, with Pete Crow-Armstrong (L, 8) and Michael Busch (L, 6) extending the back end. Seiya Suzuki (R, 5), Alex Bregman (R, 3), and Nico Hoerner (R, 1) cover the righty side, which is no slouch either at a 98 wRC+ vs RHP. Sproat's bullpen behind him is a middling unit, so an early knock-out scenario is on the table and the 6-9 spots come back up. Ownership will be heavy across the board (Bregman, Swanson, Hoerner, Happ, and Suzuki all in double-digit chalk projection territory), so the construction edge is in how you build around it, not in fading it.
Core pieces: Ian Happ (L, 4), Moises Ballesteros (L, 2), Seiya Suzuki (R, 5), Pete Crow-Armstrong (L, 8).
2. NYY vs Patrick Corbin (L) | Implied Total: 5.78 | ROO Score: 7.1/10
Pivot stack
The Yankees actually grade out as the top ROO team on the board, but the chalk attention is heavier on the Cubs spot. Yankee Stadium plays as a 115 park for RH power and Corbin is the kind of arm RH bats have feasted on for two years now. The pitcher splits back it up: his vs RHH line is 3.95 ERA on the surface but a .348 wOBA, 8.8% HR/FB, and 33% hard contact across 119 batters faced. The platoon math is even more lopsided when you look at the Yankees side: NYY righty bats vs LHP have produced a 143 wRC+, a .264 ISO, a .379 wOBA, and a 19% HR/FB rate as a team. That is the best righty-vs-lefty group in baseball. Aaron Judge (R, 2) leads the build with Amed Rosario (R, 1), Paul Goldschmidt (R, 5), and Anthony Volpe (R, 8) all in real spots. Cody Bellinger (L, 4) is the contrarian one-off if you want a one-from-each-side construction. The catch is that Judge ownership will land in the 20s, so leverage lives in the secondary bats. If you can fit two of Rosario, Goldschmidt, and Jazz Chisholm at much lower projected ownership, you get most of the upside at a fraction of the field's exposure.
Core pieces: Aaron Judge (R, 2), Amed Rosario (R, 1), Paul Goldschmidt (R, 5), Anthony Volpe (R, 8).
3. ATH vs Walbert Urena (R) | Implied Total: 4.88 | ROO Score: 5.5/10
Leverage stack
Here is where the ownership math gets fun. The Athletics are projected at single digits across the entire lineup despite a 4.88 implied total and a rookie starting pitcher in his earliest big-league looks. Urena is a soft profile (4.58 ERA, 5.45 xFIP, 5.25 SIERA) with the kind of stuff RH bats can punish, and Angel Stadium plays as a 109 park for righty power. ATH lefty bats vs RHP have produced a 118 wRC+ on the year, and the team's HR firepower number is among the best on the slate. The angle that makes this real is that Urena's catcher pairs with him as a weak framer and his bullpen has a 1.54 HR/9 behind him, so even if he escapes the first three innings the back of the start and middle relief turn into damage windows. Nick Kurtz (L, 1) is leading off with a .253 xISO and a 17.2% barrel rate, Brent Rooker (R, 4) brings the same power profile from the right side, Tyler Soderstrom (L, 3) and Carlos Cortes (L, 5) extend the lefty group, and Shea Langeliers (R, 2) has been one of the hotter bats on the slate at a 16% barrel rate. With Kurtz, Rooker, Cortes, and Soderstrom all projecting under 4% ownership, this is the way to win a GPP if the Athletics hit five runs.
Core pieces: Nick Kurtz (L, 1), Brent Rooker (R, 4), Shea Langeliers (R, 2), Tyler Soderstrom (L, 3).
Pitchers
Two clear ace-tier options and three live mid-tier shots make this a tier-stratified slate. The mid-tier is where the cash-room leverage lives if you are paying up at hitter and need to save salary in the SP slots.
Yoshinobu Yamamoto (LAD) vs SD | $9,700 | CASH
The ace anchor. Yamamoto is sitting at a 3.60 ERA, 3.92 FIP, 3.36 xFIP, .250 BABIP, with a 24.6% K rate and a 1.00 WHIP. Petco is the run-suppressing park you want for the highest-priced arm and the Padres lineup has an implied total of 3.13, which is the floor of the slate. The matchup is clean and the projection floor is the highest on the board. The only knock is the 1.44 HR/9, which is a number to keep an eye on if Padres lefties Merrill and Sheets get their pull-side swings off. In cash this is the pay-up anchor.
Shota Imanaga (CHC) vs MIL | $9,500 | CASH
Imanaga has been the slate's most efficient strikeout arm with a 2.32 ERA, 2.84 FIP, 28% K rate, and a 0.90 WHIP. Milwaukee bats are a poor matchup for any LHP: a 73 wRC+ from the LHH side vs LHP and a 77 wRC+ from the RHH side. The one open question is the Wrigley wind blowing out, because Imanaga is a fly ball arm (45% FB rate) and a small handful of those balls find the bleachers. I am still paying for the strikeout floor.
Bryan Woo (SEA) vs CWS | $9,000 | CASH
Lower-implied total game, soft White Sox offense on the road, and Woo's command profile (4.7% walk rate, 1.00 WHIP) is the cleanest in the ace tier. His K rate is in the mid-22s and his splits are nearly identical vs both sides at .275 wOBA. The game total is 7, which is the lowest on the slate, and Seattle is favored. This is the safest projection floor among the three ace arms.
Michael King (SD) vs LAD | $8,800 | GPP
The leverage spot. King is at 2.63 ERA, 3.68 FIP, 24.4% K rate, 0.70 HR/9, and Petco is the park you want behind any flyball-allowing arm. The catch is that he is facing the Dodgers, who have a 116 wRC+ vs RHP and a deep core of production from Ohtani and Betts at the top. He is the riskiest of the high-priced arms but also has a 26-point ceiling in a strikeout game. I like him better in GPP than cash because the variance is real.
MacKenzie Gore (TEX) vs COL | $8,000 | GPP
This is the contrarian GPP shot. Coors is the natural fade and Gore is projected at 6% ownership, but the weather is doing the work tonight: 41 degree first pitch, wind in from straight center, light drizzle, and a 12% HR suppression on top of a 1.3 run suppression. Gore is at 4.50 ERA but 3.95 FIP, 4.06 xFIP, and a 26% K rate on the year, and the Rockies lineup has played down to a 56 wRC+ vs RHP and a 91 wRC+ vs LHP this year. He is left-handed, which slightly tilts the matchup, and the back-end of the Rockies order is rookie heavy. If the weather holds, this is a five-inning, seven-strikeout, one-run line for $8,000. If the weather breaks, you have the contrarian win.
Pitcher Regression to Watch
Sample sizes are starting to firm up at the eight to ten start mark for most of these arms, so the regression signals are getting more reliable. Two pitchers stand out as candidates whose results are unlikely to keep matching their peripherals.
Robbie Ray (SF) at ARI | Negative Regression Candidate
The 3.04 ERA is doing a lot of lying. Ray's FIP is 4.92, his xFIP is 4.30, and the engine that has carried him this season is a 91% strand rate that is the highest in the league among qualified starters by a comfortable margin. League average LOB rate is in the low 70s. He is also running a 1.79 HR/9 on a 53% FB rate, which is a recipe for blow-up innings whenever a baserunner sticks. Arizona righty bats have been better than their season line in May, and his vs RHH split is 3.72 ERA on a .336 wOBA and 16% HR/FB, which is closer to the truth than the overall number. I am not playing him today and I am willing to take a piece of the Diamondbacks against him in GPP, particularly Geraldo Perdomo (S, 3) on the right-handed side and Corbin Carroll on the lefty side if Ray's first time through the order goes wrong.
Jose Quintana (COL) vs TEX | Negative Regression Candidate
Quintana's 3.97 ERA at Coors is the headline, but every peripheral underneath it is screaming. His FIP is 5.57, his xFIP is 5.89, his K rate is 11%, his walk rate is 11%, and his BABIP is .250 which is the lowest among slate starters. Rangers righty bats have been productive vs LHP (103 wRC+), and Quintana's split vs LHH this year has been a disaster (.435 wOBA, 4.70 ERA, 27% HR/FB on a 52% hard contact rate). Texas is heavy-RHH on this getaway day. If the cold weather were not knocking 12% off the HR rate, this is a 4-3 game stack I would be on much harder. As it is, individual bats like Brandon Nimmo (L, 2) and the Burger-Jung-McCutchen run from spots 3-5 are the targets in GPP, not Texas as a full stack.
Final Thoughts
The cash core comes together around Yamamoto or Imanaga in the pitcher slot, Bregman or Suzuki as the CHC stack anchor, and Aaron Judge as the single highest-floor bat on the slate. There is no real game stack on the board tonight. The 10.5 CHC vs MIL total looks the part on paper, but the implied totals are a 6.24 to 4.26 split with Imanaga starting against a Brewers lineup that grades poorly vs LHP. That is a one-sided slate, not a back-and-forth. Single-side CHC is the cleaner construction. The same goes for COL vs TEX: the 9.5 total is misleading because the cold/wind/rain combo is knocking 12% off home runs and Quintana is the only pitcher in that game with an extreme peripheral story. Stick to the Cubs as your primary anchor and use the rest of your salary to get unique elsewhere.
The GPP leverage is in three places. The ATH stack at single-digit ownership across the board, with Kurtz, Rooker, and Soderstrom anchoring. Buxton at $6,200 in a leadoff spot against a 9.24 ERA arm in a slate where most lineups are paying for Judge or a CHC bat instead. And Casey Schmitt at $3,800 batting third against a Gallen who has been getting punished by righty contact all year. When the Cubs stack runs 30%+ chalk in your contest size, the leverage moves to the bottom of the order rather than the fade: Pete Crow-Armstrong (8) and Carson Kelly (7) at lower ownership give you most of the same ceiling at a fraction of the field's exposure.
