Weather to Watch
Boston at Athletics | Sutter Health Park | Clear, 94F | Wind: 11 mph SW
Ninety-four in the valley with an 11 mph breeze headed out. My numbers add better than 20% to home run odds here, and the right-handed bats collect the biggest share of it.
Kansas City at Minnesota | Target Field | Clear, 94F | Wind: 3 mph S
The air is nearly still, and it does not matter. Ninety-four degrees with bone-dry humidity moves the ball plenty by itself, a 13% bump to homers for both dugouts on my read.
Cleveland at Cincinnati | Great American Ball Park | Clear, 83F | Wind: 9 mph N
A crosswind angled toward the right field seats hands lefty swings roughly a 16% boost tonight. This park in late July hardly needs the assist.
Chicago Cubs at St. Louis | Busch Stadium | Clear, 89F | Wind: 8 mph NNE
The wind blows in and the thermometer wins anyway. Eighty-nine degree air outmuscles an 8 mph headwind on my numbers, so I am treating Busch as mildly hitter friendly rather than neutral.
Houston at Los Angeles Angels | Angel Stadium | Clear, 79F | Wind: 7 mph SW
Warm evening air with a light flow out to center, a modest plus for both lineups. Nothing here should change a build.
Seattle at Los Angeles Dodgers | Dodger Stadium | Clear, 74F | Wind: 7 mph WSW
A gentle push toward the pavilions that favors lefty swings a touch. Background noise, mostly.
New York Yankees at Chicago White Sox | Rate Field | Clear, 71F | Wind: 7 mph N
The closest thing to neutral on the board. Cool air, a small breeze out, and no reason to move anyone up or down because of it.
HR Calls
Yordan Alvarez (HOU) $6,500 vs Grayson Rodriguez
There are matchups you talk yourself into, and then there is Alvarez against Rodriguez. Lefties are slugging .656 off the Angels righty while striking out just 11% of the time, and his BB/9 north of four means he spends whole innings behind in counts, throwing the fastball he has to throw rather than the one he wants to. Alvarez is treating right-handed pitching the way he always has, 26 homers, a .340 ISO, and hard contact above 57% in the split, and his ISO over the last 30 days is running north of .450. Angel Stadium holds lefty power down some. I am not letting a park factor talk me off this one.
Julio Rodriguez (SEA) $4,300 vs Eric Lauer
DraftKings has let Rodriguez drift to $4,300, and that price ignores who he becomes when a southpaw is on the mound. He owns a .362 wOBA off southpaws with 8 homers in just 114 plate appearances, and better than a quarter of his fly balls off lefties have left the yard. Lauer is the other half of the argument: 16 homers already served to right-handed bats at a 2.19 HR/9, a 13% strikeout rate that concedes contact, and a fly ball profile that keeps everything in the air. Something has to give here, and I think it is a baseball.
Romy Gonzalez (BOS) $3,400 vs Jacob Lopez
I can argue against Gonzalez myself, 36 plate appearances versus lefties this season is nothing, so let me explain why I keep landing on him anyway. When he has seen southpaws he has hit them hard over half the time, and a quarter of his fly balls in the split have gone out. Lopez is the real sell: righties have reached him for a .383 wOBA and a .500 slugging mark with a 1.81 HR/9, and a walk rate above 13% keeps him pitching from behind, forced into the zone with hitters sitting on it. Sacramento's 94-degree evening adds better than 20% for right-handed power on top. At $3,400, hitting sixth in the highest-implied lineup on the slate, he is my favorite cheap swing of the night.
Stacks to Target
1. Boston Red Sox vs Jacob Lopez (L) | Implied Total: 6.12 | ROO Score: 6.3/10 | Cash
No lineup has a friendlier evening in front of it than Boston. Lopez has more or less survived lefties this year, but right-handed bats own him, a .383 wOBA and .500 slugging with nine homers allowed in that split, and he has averaged barely three innings across his last five starts. That short leash matters because the Athletics relief corps waiting in the wings runs a 5.92 xFIP with a 2.14 HR/9 attached, among the softest groups I can roster against. Boston's right-handed heart supplies the platoon edge: Contreras is hitting lefties to a 173 wRC+, Rafaela to a 141, Gonzalez brings the loud small sample, and Abreu has hit southpaws well enough this season that I am not benching him over handedness. Add the best hitting weather in baseball tonight and this is the cash stack, whatever the ownership tax ends up being.
Core pieces: Willson Contreras $5,400 (R), Wilyer Abreu $4,900 (L), Ceddanne Rafaela $4,400 (R), Romy Gonzalez $3,400 (R), Jahmai Jones $2,100 (R)
2. Minnesota Twins vs Randy Dobnak (R) | Implied Total: 5.24 | ROO Score: 5.6/10 | GPP
Dobnak is the pitcher I most want my hitters facing tonight, sub-1.50 ERA and all. He has stranded better than 97% of his baserunners, opponents are hitting .254 on balls in play, and his 12.5% strikeout rate sits barely above his walk rate; an ERA built like that across 18 innings is borrowed, and Minnesota is positioned to collect. This order fits the matchup because the righty bats handle right-handed pitching: Buxton's 21 homers off righties come with a .326 ISO, Jeffers is at a .391 wOBA there, and the lefties Larnach and Clemens both clear a 115 wRC+ against righties as well. Kansas City's relief group has been generous all year, so the scoring window stays open after Dobnak leaves. Ninety-four degrees at Target Field does the rest. The Twins project for noticeably less attention than the other big implied totals, which is why they are my favorite tournament stack instead of a cash lock.
Core pieces: Byron Buxton $6,000 (R), Ryan Jeffers $5,500 (R), Kody Clemens $5,000 (L), Trevor Larnach $4,200 (L), Josh Bell $3,400 (S)
3. Houston Astros vs Grayson Rodriguez (R) | Implied Total: 5.22 | ROO Score: 5.1/10 | Cash
Houston projects as the most popular stack of the night, and for once I think the crowd has it right. Rodriguez wears an 8.54 ERA that overstates the misery, his xFIP is closer to five and a half and a .349 BABIP has piled on, but the 4.4 BB/9 is real and lefties are slugging .656 against him. Alvarez gets the spotlight, and the righties behind him keep the stack honest: Paredes at a 120 wRC+ versus righties, Walker with 16 homers off that side, Pena setting the table in front of all of it. Anaheim's bullpen sits below average with a 1.41 HR/9, so a short start feeds a soft middle game. This is the chalk-safe half of my cash core next to Boston.
Core pieces: Yordan Alvarez $6,500 (L), Jeremy Pena $4,800 (R), Isaac Paredes $4,100 (R), Jose Altuve $4,000 (R), Christian Walker $3,900 (R)
Pitchers
Cam Schlittler (NYY) vs CWS | $10,800 | CASH
Every slate has an obvious answer, and Schlittler is this one's. A 2.08 ERA with a 2.79 xFIP underneath, a strikeout rate over 30%, and walks handed to fewer than 5% of hitters is about as complete as a pitching profile gets, and the White Sox carry the lowest implied total on the board at 3.21. If I am nitpicking, an 81% strand rate and an unusually low homer count say a little of the shine is loaned rather than earned. It does not matter against this lineup. He anchors my cash rosters, and he will anchor most of yours too.
Joe Ryan (MIN) vs KC | $10,300 | CASH
Is there room for two arms above $10,000 tonight? I think this slate allows it. Ryan's season is clean in a way I rarely get to write, a 3.39 ERA against a 3.25 xFIP with a 27.8% strikeout rate and almost no free passes, and Kansas City is implied for barely three and a quarter runs. The one blemish is left-handed power, a 1.69 HR/9 in that split, and the Royals do carry young lefty bats with thump in 94-degree air, so I budget a solo shot into the night. Popular, and deservedly so. If salary forces a choice between him and Schlittler, I lean Schlittler, but the gap is smaller than the price difference suggests.
Matthew Boyd (CHC) vs STL | $7,700 | CASH
Boyd's season will not make a highlight reel, and that is sort of the point. His 3.81 ERA and 3.73 xFIP agree with each other, which is all I ask from a mid-priced arm, and St. Louis checks in at a 3.73 implied total, near the bottom of the slate. Righties have touched him for a .321 wOBA, so this is a floor purchase more than a ceiling one, six competent innings with five or six strikeouts, and the two thousand in savings under the big arms is what lets a roster carry the Boston bats.
Davis Martin (CWS) vs NYY | $8,300 | GPP
Start with what is wrong: New York's 4.29 implied total is no soft landing, and Martin's 4.9% HR/FB rate will climb sooner or later. What is right is quieter. The 3.49 ERA carries a matching 3.56 xFIP, he keeps the ball on the ground more than 45% of the time, and hitters from either side have slugged under .370 against him this season. He also projects among the least-rostered of the mid-priced arms, which is the entire appeal in tournaments. If the Yankees get to him, the low attention means it will not bury a large-field entry the way a Schlittler dud would.
Dustin May (STL) vs CHC | $7,500 | GPP
May has pitched better than he has been paid off. The 4.59 ERA rides a .336 batting average on balls in play and a 65.6% strand rate, while a 3.62 xFIP and a 24.7% strikeout rate against righties describe a real arm underneath. Profiles like his tend to correct without warning. The catch is that Chicago's lefty bats are the wrong medicine, a .344 wOBA allowed in that split with most of his walks landing there, and an 89-degree Busch evening does him no favors. In tournaments I want shares anyway. He sits at the bottom of the ownership pecking order among tonight's legitimate starters, and buy-low strikeout arms are how leverage gets cheap.
Pitcher Regression to Watch
Randy Dobnak (KC), Negative Regression Candidate
Eighteen innings into his Kansas City run, Dobnak owns a 1.48 ERA with almost nothing underneath holding it up. He has stranded better than 97% of baserunners, opponents are hitting .254 on balls in play, and a 12.5% strikeout rate next to a 5.41 xFIP is the profile of a five-ERA arm wearing a one. The Twins section above is built on this read, so I will keep it short: a correction is due, and 94-degree air is a rough place to take it.
Dustin May (STL), Positive Regression Candidate
May is the other direction, and I backed the read by putting him in the Pitchers section. A .336 BABIP and a 65.6% strand rate have taxed nearly a full run onto his 4.59 ERA relative to a 3.62 xFIP, while his strikeout and walk rates held steady through the stretch where the results wobbled. Buy-low windows like his close the first time seven shutout innings show up on a box score. Whether that happens tonight against a Cubs order with real left-handed pop, I am less sure, which is why I keep him in tournaments only.
Final Thoughts
My cash frame: Schlittler as the anchor, Boyd as the second arm when salary tightens, and the bat core split between Boston and Houston, Contreras and Rafaela against Lopez with Alvarez and Paredes on the other side. Jones at $2,100 and Gonzalez at $3,400 are the two prices that make the whole thing fit, and both hit in the best power conditions on the board. If a build lands a few hundred short, trimming Pena down to Walker at $3,900 is the easiest cut.
Two things before lock. The Sacramento heat is baked in, but the 11 mph outbound wind is the piece of my Boston math worth rechecking once the evening reading comes in. The other is Wesneski, who has not logged a start yet this season; an arm in that position usually works on a strict pitch count, which would push Houston's bullpen into the game early and shape the late innings on the Angels side.
For tournaments, Minnesota over the chalkier stacks is my central move, and the full argument lives in the stack section and the Dobnak writeup. A Julio Rodriguez and Arozarena pairing against Lauer is the cheaper second angle, righty bats against a lefty who has already served 16 homers to that side. If Wesneski does exit early, the Angels get more of their night against relievers instead of a settled starter, and Trout at $5,200 is the bat I would use to chase that. May and Martin are the arms that separate a lineup from the crowd.
