Weather to Watch

Eight game slate, all evening starts at 6:05 CT or later. Five of the eight games are in domes, so the weather conversation is short. Three outdoor games matter for HR pricing.

CWS at Chicago | Rate Field | Clear, 71F | Wind: 14 mph WNW

Wind is blowing out to right center at the friendliest park on the slate. The model has this game at a 10.7% HR boost, the largest on the board. Rate Field plays as a bandbox in this wind profile and both lefty and righty pull bats benefit.

SF at San Francisco | Oracle Park | Clear, 60F | Wind: 18 mph WNW

This is the trickiest weather read on the slate. Wind is out at 18 mph, but it is 60 degrees with marine air, which kills carry. The HR impact pencils out to a 9.3% boost, but Oracle has not played up even when the wind looks right in past games. I am treating this as a small bump, not a runs feast.

DET at Kansas City | Kauffman Stadium | Overcast, 78F | Wind: 7 mph WSW

Light wind out, warm air, and a small precip risk at 11%. Nothing to scrub the slate over, but Kauffman gets a small bump and KC owns the highest implied total on the board, so the conditions reinforce the matchup.

The other outdoor games at LAD and SD are neutral and the four domes are static. No rain risk on the slate worth flagging beyond the small Kauffman watch.


HR Calls

Munetaka Murakami (CWS) $5,900 vs Luis Castillo

[STANDARD MODEL]

This is the call of the slate for me. Murakami sits on a 38.5% HR/FB rate, a 22.1% barrel rate, and a 45.5% pull rate, which is the exact profile that turns Rate Field's wind-out conditions into runs. Castillo has been a mess in 2026 with a 6.29 ERA, a 1.05 HR/9, and a 45% fly ball rate vs lefties, and lefties are slugging a .456 wOBA against him with a 9.4% HR/FB. Salary has not caught up to either the matchup or the weather here, and ownership is sitting in low single digits.

Riley Greene (DET) $4,300 vs Michael Wacha

[SLEEPER MODEL]

This is the regression call. Wacha sits on a 3.05 ERA but his xFIP is 4.46, a 1.41-run gap built on a .230 BABIP and a 80% LOB rate, both of which scream luck rather than skill. Greene's xISO is .237 with a 15.4% barrel rate vs righties, and his actual ISO has been quietly underwater. Wacha runs a 48.6% fly ball rate against lefties, Kauffman is wind-out tonight, and Greene is hitting fourth. Salary is the bonus.

Max Muncy (LAD) $4,400 vs Spencer Strider

[STANDARD MODEL]

The Strider rehab matchup is the soft spot the slate is sleeping on. Strider has 3.1 innings on the year and his only meaningful sample vs left handed bats is a .542 wOBA with a 25% HR/FB. Muncy has a 20% HR/FB, a 16.3% barrel rate, and a 47.7% pull rate, all on a .279 xISO that has him near the top of the sleeper sheet too. Dodger Stadium with a 123 park factor for lefty power, hitting sixth where ownership stays manageable, this is the GPP power play that fits both models.


Stacks to Target

1. LAD vs Spencer Strider (R) | Implied Total: 5.17 | ROO Score: 6.9/10

Top ranked stack on the slate and it is a rehab spot, not a fully healthy ace. Strider has 3.1 innings on the year coming back from injury, and the early sample is an 11.57 ERA vs left handed bats with a .542 wOBA and a 25% HR/FB. The Dodgers run a 131 wRC+ vs RHP from their lefty bats this season, which is a top-three mark in baseball, and they get a tired bullpen behind the starter (BP ERA 4.35, K-BB 15.2%) once Strider exits. Park factor at Chavez Ravine is 123 for lefty home runs in this wind profile. The chalk is real on Ohtani and Freeman, but the construction matters more than the leverage in cash, and Muncy and Pages give you GPP differentiation in the same lineup.

Core pieces: Shohei Ohtani (LHB, leadoff), Freddie Freeman (LHB, two hole), Max Muncy (LHB, six hole), Andy Pages (RHB, seven hole, 162 wRC+ vs RHP).

2. SEA vs Anthony Kay (L) | Implied Total: 5.23 | ROO Score: 6.7/10

Kay is the platoon sledgehammer of the slate. He has a 1.17 ERA and a .157 wOBA against lefties this year, but vs righties he is at a 7.25 ERA, a .456 wOBA, and a 17.1% HR/FB across 113 batters. The Mariners' top right handed bats are exactly the players you want pointed at that hole. Julio Rodriguez has a 168 wRC+ vs LHP this year and Randy Arozarena is at 131. Cal Raleigh turns around to bat right vs lefties as a switch hitter and has elite power either way. Add the Rate Field wind-out HR boost on top and this is the slate's cleanest leverage stack against a lefty starter, with ownership a tier below the Dodgers.

Core pieces: Julio Rodriguez (RHB, three hole), Cal Raleigh (SHB, two hole, hits R vs L), Randy Arozarena (RHB, five hole), J.P. Crawford (LHB, leadoff).

3. KC vs Burch Smith (R) | Implied Total: 5.32 | ROO Score: 6.4/10

The highest implied total on the slate, sitting against a low-sample arm in Burch Smith with 11.1 innings on the year. The model treats Smith on a baseline-vulnerability rating because the sample is too small to read properly, and Kauffman in a wind-out spot pushes the run environment further. KC's lefty bats run a 113 wRC+ vs RHP, and the bullpen behind Smith is a 4.05 ERA group with a 3.8 BB/9, so once Smith exits the run scoring tap stays on. The platoon angle here is clear: KC is much better LHH vs RHP than RHH vs RHP, so prioritize the lefty bats in the lineup.

Core pieces: Vinnie Pasquantino (LHB, three hole), Bobby Witt Jr. (RHB, two hole), Kyle Isbel (LHB, lower order, 126.8 wRC+ vs RHP), Carter Jensen (LHB).


Pitchers

Two strong arms at the top, then a mid-tier with one boom-bust returner and a couple of value plays. Salary range goes from $10,700 down to $5,500 if you want to free up bats.

Cam Schlittler (NYY) vs MIL | $10,700 | CASH

The slate locker. Schlittler has a 1.52 ERA across 47.1 innings with a 29.3% strikeout rate, a 1.74 FIP, a 0.86 WHIP, and a 0.19 HR/9 that is the best mark on the slate. Milwaukee runs a 70 wRC+ as a team vs righties from their lefty side and the broader lineup is the bottom of the slate at a 3.3 implied total. Even with the high ownership baked in, this is the highest projection arm on the slate by a wide margin and the one I want anchoring cash.

Landen Roupp (SF) vs PIT | $9,200 | CASH

The other cash arm. Roupp has been excellent at a 3.18 ERA across 39.2 innings with a 2.66 FIP that leads the slate, a 27% K rate, and a 0.23 HR/9. Pirates run an 81 wRC+ vs RHP from their right handed bats. The wind-out at Oracle is a small concern, but Pittsburgh does not have the lefty pull power to seriously threaten and the floor here is excellent for the salary.

Edward Cabrera (CHC) vs TEX | $7,400 | CASH

The salary value of the slate. Cabrera sits at a 3.27 ERA across 41.1 innings, a 4.01 FIP, a 21.6% strikeout rate, and the dome at Globe Life keeps the HR risk under control. Texas runs a 102 wRC+ vs RHP this year, not scary, and at $7,400 he gives you pivot room to pay up at a stack spot.

Blake Snell (LAD) vs ATL | $9,200 | GPP

The boom or bust returner. Snell does not have meaningful 2026 numbers because he is just back from injury, but ATL has been below average in their RHH vs LHP split (97 wRC+) and the matchup is the softer side for a lefty arm. This is the upside lever for GPPs where you want a different SP from the Schlittler and Roupp chalk pair. Floor is real risk because of the rehab status, but the ceiling is elite if Snell is healthy.

Braxton Ashcraft (PIT) vs SF | $7,700 | GPP

The mid-tier GPP arm. Ashcraft has a 3.02 ERA across 41.2 innings with a 2.99 FIP, a 27.3% strikeout rate, and a 1.08 WHIP. SF runs a 1.3 offense ceiling per the ROO model, the worst lineup on the slate. The wind-out at Oracle is the only knock. At $7,700 this is GPP value with K upside.


Pitcher Regression to Watch

Two arms with meaningful innings where the ERA and the peripherals are telling different stories. Both starters here have north of 35 IP, so the regression signal is reliable.

Michael Wacha (Negative Regression Candidate)

Wacha sits on a 3.05 ERA across 44.1 innings, but his FIP is 4.06, his xFIP is 4.46, and his BABIP is .230 with a 80% LOB rate. That is a 1.41-run gap between ERA and xFIP, propped up by both batted-ball luck and stranded runners. His K rate is fine at 21%, but he is allowing a 1.02 HR/9 and a 48.6% fly ball rate vs lefties. The implication is that KC's opposing offense is a better stack target than the ERA suggests, especially in a wind-out spot at Kauffman. Reinforces the KC stack call above.

Jack Leiter (Positive Regression Candidate)

The other side of the coin. Leiter has a 5.45 ERA across 38 innings, but his xFIP is 3.44 and his SIERA is 3.53. He runs a 13.7% swinging strike rate, a 26% K rate, a 12.5% K-BB margin, and a 77% LOB on the year that is below average. The 1.66 HR/9 is the only stat dragging him down, and most of that lives in the FIP gap. The implication is that CHC's stack against Leiter is not the slam dunk the ERA suggests, especially with the dome neutralizing the wind variable. The Cubs are still a top-five offense vs RHP, but expect a tougher path than the surface numbers imply. Position him as a GPP fade-the-stack lever, not a panic stack.


Final Thoughts

Cash construction starts with Cam Schlittler at the top of the pitcher pool and a Dodgers core stack against the Strider rehab spot. Pair Schlittler with Landen Roupp for the second cash arm and you have your foundation. From there, anchor with Ohtani and Freeman, fill in Will Smith or Andy Pages for catcher and outfield leverage, and use Pasquantino as a lefty one-off bat against Burch Smith if you want a one-off from the KC side.

The biggest pre-lock watch list is the Strider start. If the rehab stretch gets a late scratch or pitch count alert, the Dodgers stack changes from chalk to total no-brainer, and Snell on the other side either becomes more or less attractive depending on whether ATL leans into a lefty heavy lineup. The Kauffman precip note is small but worth a refresh, and the Oracle wind direction can shift between now and lock so check the weather page for the SF and PIT bats one more time.

GPP pivots I am most willing to be different on: the SEA stack against Kay (lower owned than the Dodgers, similar ROO ceiling), Edward Cabrera as the salary value pitcher to free up two stacks, and Murakami at sub-2% ownership in the standard HR model is the leverage power play of the slate. Where I am unwilling to be different is the SP1 spot. Schlittler is the slate, the chalk is correct, and any cute pivot off him is paying upside tax for ownership relief that does not justify itself.
