Red Sox, Yankees, Brewers and Diamondbacks Moneylines: Four Favorites, One Price Band

Five cents. That is the entire spread between the cheapest and the most expensive side on this card. Boston costs -136, Arizona -133, Milwaukee -132, New York -131. Four teams, four completely unrelated arguments, and a market that has decided all four deserve the same toll. One of these teams has won fourteen consecutive games. Another is handing the baseball to a pitcher who has never thrown a major league inning in his life. The number does not care, so the work is figuring out where the flat pricing is generous and where it is a trap.

Diamondbacks Moneyline: The Road A's Have Stopped Hitting

The biggest stake on the card goes on the team with the least reassuring starting pitcher, which requires an explanation. Arizona's listed probable is Kohl Drake, a 26-year-old left-hander who has no major league debut date and no major league statistics to his name. That is not a knock on him. It is simply the honest starting point: this bet is not about the man on the mound for the Diamondbacks.

It is about what happens to the Athletics when they leave home. Oakland's lineup at home hits .268 with a .348 on-base percentage and an .808 OPS. On the road that same group collapses to .227, a .300 on-base percentage and a .651 OPS, a gap of 157 points of OPS. They arrive in Phoenix having lost eight of their last ten with a team ERA of 5.29 and 559 runs allowed, the worst mark in the American League. Jack Perkins takes the ball for them carrying a 6.87 ERA and a 1.44 WHIP across 57.2 innings, and he is a two-pitch shape guy in practice, throwing his four-seamer 36.7 percent of the time and a sweeper 30.3 percent, with a changeup filling the remaining gap. A sweeper-heavy right-hander in a warm desert park against a lineup that has already tagged him for ten home runs in under 58 innings is a fine place to attack.

Arizona has the bullpen depth to cover a short outing. Their relievers threw 15.3 innings over the July 18 through July 20 stretch, with Ryan Thompson, Jonathan Loaisiga, Brandyn Garcia and Kevin Ginkel each appearing twice, so the arms have been worked but nobody is buried. At -133 the market is asking for roughly a 57 percent win probability from a 51-49 home team against a 43-57 road team that cannot hit outside its own ballpark. Three units on the Diamondbacks moneyline at -133.

Yankees Moneyline: Bubba Chandler Cannot Find The Strike Zone

Pittsburgh's Bubba Chandler has electric stuff. His four-seamer averages 98.5 mph and he throws it 47.9 percent of the time, backed by a changeup at 91.8 and a slider at 90.2. He is 23 years old and the arm is real. He has also walked 55 hitters in 94.1 innings this season, a rate north of five per nine, and that is the entire reason this play exists.

Free passes travel badly into Yankee Stadium, where the Yankees have hit 146 team homers as a team, more than anyone else on tonight's board. New York's home slugging percentage sits at .443 against a .238 average, which is exactly the profile of a lineup that does not need many baserunners to do damage. Give that group five walks and one mistake and the game turns in a single inning.

On the other side, Will Warren has been steady rather than spectacular, a 4.03 ERA over 98.1 innings with 96 strikeouts, working off a 38.5 percent four-seamer at 93.6 and a 27.2 percent sinker. Warren does not have to be great. He has to be adequate in front of a pitching staff whose 3.42 team ERA is the lowest in baseball. The Yankees have won two straight and are 31-22 away from home, an odd split for a team playing at home tonight, and we will come back to that. Two and a half units on the Yankees moneyline at -131.

Red Sox Moneyline: Fourteen Straight And Still Only -136

Boston has not lost a baseball game since July 1. Fourteen in a row. It started with a 5-2 win in Anaheim on July 3 and ran through three-game sweeps of the Angels, the White Sox and the Mets, then a four-game sweep of Tampa Bay coming out of the break that included a 10-0 shutout on July 17, and then a 6-5 win over Baltimore on Monday night. Ten and zero in their last ten. A team that was buried in the American League East is suddenly six games back of the Rays.

Tonight they hand the ball to Ranger Suarez, who has been the quietest good starter in the league: a 3.15 ERA, a 1.16 WHIP and only five home runs allowed in 91.1 innings. The left-hander works from a genuinely six-pitch mix, sinker 23.7 percent, four-seamer 21.9 percent, cutter 20.6 percent, curveball 16.8 percent, changeup 14.4 percent, and the shape variety is why he almost never gets barreled. Baltimore against left-handed pitching hits .232 with a .698 OPS, and their road numbers are worse still at .225 and a .682 OPS.

The Orioles also just lost, snapping their own good stretch, and they have allowed 478 runs on the season, more than they have scored. Boston's bullpen is in reasonable shape after throwing just 10.3 innings over the last three days, with Aroldis Chapman, Garrett Whitlock and Ryan Watson each up twice. Fourteen straight wins and a 3.55 team ERA should cost more than -136 at home. Two units on the Red Sox moneyline at -136.

Brewers Moneyline: The Best Record In Baseball For A Flat Price

Milwaukee is 63-37, tied for the best record in the sport, winners of four in a row, and 33-18 at American Family Field. Across from them is a 42-59 Mets club that is 21-31 on the road and has scored the second-fewest runs of any team on this card. New York's lineup against right-handed pitching hits .233 with a .683 OPS. That is the shape of the mismatch, and it is why the play still makes the card even at a stake we are deliberately keeping small.

The reason the stake is small is Brandon Sproat. Milwaukee's starter has a 5.16 ERA and a 1.37 WHIP over 82 innings, and he has surrendered 15 home runs, the most of any starter in tonight's four games. His pitch mix is unusually flat, sinker 24.6 percent, cutter 24.1 percent, four-seamer 23.3 percent, and when a starter distributes that evenly without a genuine put-away weapon, bad nights arrive in bunches. Milwaukee's relievers have logged 12 innings across the last three days, which is manageable but not fresh.

New York counters with Zac Thornton, a 24-year-old lefty with a 2.60 ERA in 17.1 innings across three starts. The sample is tiny, and tiny samples are exactly how a bad team steals a game from a good one. So this is a real edge at a modest price rather than a hammer. A unit and a half on the Brewers moneyline at -132.

What Can Beat It

Start with the Yankees, because the counterpoint there is loud. New York's bullpen threw 20 innings in three days, by far the heaviest workload of any team on this card. Tim Hill and Angel Chivilli each pitched three times in that window, and Jake Bird and Camilo Doval twice apiece. If Warren gives back five innings instead of six, Aaron Boone is reaching into a tired pen against a Pittsburgh lineup that hits .266 with a .786 OPS against right-handed pitching and has scored 538 runs, the most of any team playing tonight in these four games. That is the single most uncomfortable number on the page.

Boston's flaw is the mirror image of its streak. The Red Sox are 22-27 at Fenway Park and 29-21 on the road, which means the fourteen-game run has been built substantially away from home. Their lineup against right-handed pitching hits just .239 with a .685 OPS, and Kyle Bradish is a right-hander with a 3.61 ERA and a 33.8 percent sinker who has held opponents to a .237 average. Streaks end, and they usually end against a competent starter.

Arizona's risk is the obvious one. Handing a debut to a pitcher with zero big-league innings while laying a price is uncomfortable, and it gets worse when you notice the Athletics actually hit left-handed pitching better than right-handed pitching this season, .742 OPS against lefties versus .725 against righties. Arizona's own lineup is the weakest of the four teams we are backing, a .667 OPS against right-handed pitching. And Milwaukee's exposure is simply Sproat: if his fifteenth, sixteenth and seventeenth home runs show up tonight, the best record in baseball will not save the ticket. Every one of those numbers is priced into the stake sizes above.

The Bottom Line

Nine units across four sides, all inside a five-cent band. The Diamondbacks at -133 get the largest stake because the Athletics' road bat, a .651 OPS away from their own ballpark, is the single clearest weakness available to attack tonight. The Yankees at -131 are a bet on Chandler's 55 walks finding the wrong ballpark. The Red Sox at -136 are the cheapest fourteen-game winning streak the market will sell you this month, with Ranger Suarez and his five home runs allowed on the mound. The Brewers at -132 are a small stake on the best record in the sport against a 21-31 road team, sized down because Sproat's 5.16 ERA is a genuine liability. Flat pricing across four different arguments is a gift when you are willing to grade the arguments individually.
