4-Leg Prop Combo Longshot (Editor's Pick)
We're taking a swing at a four-leg combo tonight instead of a single contract. Every leg on its own is a live price, but stacking all four together is what turns this into a true longshot play.
- Leg 1 is Yordan Alvarez going deep against the Yankees, currently the richest home run price on the Astros-Yankees board at 26¢. Houston has already been pitching around him this week, walking him intentionally multiple times, which tells us how much respect his bat is getting even in a down stretch for the Astros lineup.
- Leg 2 is Kazuma Okamoto to homer against Toronto, priced at 18¢, tied for the top home run price on the Royals-Blue Jays board. Okamoto and the rest of the Kansas City lineup are seeing Max Scherzer, who has allowed 12 home runs and carries a 7.40 ERA this season, so the whole Royals home run market is inflated for good reason.
- Leg 3 is Adrian Houser going over 3.5 strikeouts for the Giants, priced at 58¢ on the current board.
- Leg 4 is Brady Singer going over 4.5 strikeouts for the Reds, priced at 45¢, rounding out a combo that leans on two starters who miss enough bats to clear those thresholds on a good night.
The ticket itself shows a combined 70.41x payout across the four legs.
A $5 event contract purchase at that multiple would return $352.05 if every leg hits, for a profit of $347.05 on the $5 stake.
- If all four legs settle Yes: the position pays out at 70.41x, turning $5 into roughly $352.05.
- If even one leg misses: the entire $5 stake is lost, since Polymarket combos settle all-or-nothing across every leg.
Make no mistake, this is a huge longshot. A 70.41x payout implies roughly a 1.4% chance of hitting, so this is a small, speculative stake rather than a core position, and it needs all four props to land on the same night to cash.

Yankees vs Astros: Best MLB Player Props Today
New York (74-56) enters on a one-game win streak and is pulling away in the AL East, while Houston (65-66) has dropped five of its last nine and just parted ways with general manager Dana Brown.
Yankees righty Will Warren (8-6, 4.43 ERA) faces Astros rookie Ethan Pecko (0-0, 4.91 ERA), who is making just his second career start.
Moneyline
- Houston Astros (43¢, implying 43%): the Astros are getting a discount despite the recent skid, with the market still respecting a lineup that includes Alvarez, Altuve and Bregman-caliber power up and down the order.
- New York Yankees (58¢, implying 58%): the Yankees are favored at home behind a hotter recent stretch and a healthier pitching staff, with the market pricing them as clear favorites in this Yankees vs Astros opener.
Spread and Total
- Astros +1.5 (61¢) / Yankees -1.5 (40¢): the run line still favors New York covering, though at a shorter price than the moneyline suggests given how competitive recent Astros losses have been.
- Over 8.5 (52¢) / Under 8.5 (49¢): the total sits almost dead even, with both lineups capable of scoring in bunches against shaky bullpens.
Home Runs
These home run props for Yankees vs Astros are ranked below by Yes price, from most to least likely on the board. Some contracts on this board only have one side actively priced, so a couple of entries below show just the Yes side.
- Yordan Alvarez (Home Run: 26¢ Yes, 79¢ No): the top price on this board, and Houston has been walking him intentionally rather than letting him beat them, a sign the market is right to respect his power even in a rough patch for the team.
- Ben Rice (Home Run: 22¢ Yes, 79¢ No): Rice has quietly been one of the more productive bats in the Yankees lineup and gets a favorable price here as New York's second-best home run option.
- Spencer Jones (Home Run: 17¢ Yes, 84¢ No): the rookie outfielder's raw power keeps him in the mix against a Houston staff that has a 5.04 ERA over its last 14 games.
- Luis Garcia Jr. (Home Run: 17¢ Yes): Garcia has pop from the right side and this price reflects a real chance against a Yankees pitching staff that has been generous with the long ball lately.
- Trent Grisham (Home Run: 17¢ Yes, 86¢ No): Grisham has been swinging a hot bat recently and sits right alongside Jones and Garcia at 17¢.
- Cody Bellinger (Home Run: 16¢ Yes, 90¢ No): Bellinger has been working back from a hamstring issue and was seen running the bases in pregame warmups, a good sign for his availability and pop tonight.
- Jazz Chisholm Jr. (Home Run: 15¢ Yes): Chisholm's speed-power combination keeps him priced above most of the Astros' everyday lineup.
- Austin Wells (Home Run: 14¢ Yes): the Yankees catcher has enough thump to stay in the double digits on this board.
- Daulton Varsho (Home Run: 14¢ Yes, 92¢ No): Varsho rounds out the Yankees' everyday power options at a matching 14¢.
- Christian Walker (Home Run: 13¢ Yes, 91¢ No): Walker has said the Astros are underperforming their talent level, and this price reflects a lineup still trying to find its rhythm.
Blue Jays vs Royals: Best MLB Player Props Today
Kansas City (58-74) has won eight straight games and arrives in Toronto red hot, while the Blue Jays (64-68) sit two games back of a wild card spot after losing two of three to the Yankees over the weekend.
Toronto starter Max Scherzer (1-6, 7.40 ERA) has allowed 12 home runs in just 45 innings this year, and he faces Seth Lugo (5-7, 4.71 ERA) for Kansas City.
Moneyline
- Kansas City Royals (45¢, implying 45%): the Royals are getting real value here given their current win streak, and the market still can't fully shake Scherzer's name recognition despite his 2026 numbers.
- Toronto Blue Jays (56¢, implying 56%): Toronto is favored on home cooking in this Blue Jays vs Royals opener, but the gap is thinner than the win totals alone would suggest.
Spread and Total
- Royals +1.5 (63¢) / Blue Jays -1.5 (38¢): the run line leans heavily toward Kansas City staying within a run and a half, which lines up with Scherzer's shaky recent form.
- Over 8.5 (48¢) / Under 8.5 (53¢): the total actually leans slightly to the Under here, even with a home run rate against Scherzer that would seem to argue for the Over.
Home Runs
These home run props for Blue Jays vs Royals are ranked below by Yes price, from most to least likely on the board. A handful of Royals contracts on this board only have one side actively priced, so those entries show just the Yes side.
- Carter Jensen (Home Run: 18¢ Yes, 83¢ No): Jensen sits at the top of this board, part of a Kansas City lineup taking full advantage of a Scherzer start that has produced 12 homers allowed all season.
- Kazuma Okamoto (Home Run: 18¢ Yes, 85¢ No): Okamoto is the same price as Jensen and is the leg we used in tonight's editor's pick combo above.
- Bobby Witt Jr. (Home Run: 18¢ Yes, 88¢ No): Witt rounds out the three-way tie at the top, and he's been a driving force behind Kansas City's eight-game surge.
- Salvador Perez (Home Run: 17¢ Yes, 86¢ No): Perez remains one of the most dangerous power bats in this lineup even in his age-36 season.
- Vinnie Pasquantino (Home Run: 16¢ Yes): Pasquantino's left-handed pop makes him a live option against Scherzer's home run rate.
- Michael Massey (Home Run: 13¢ Yes, 89¢ No): Massey has settled into a middle-of-the-order role and gets a fair price against a struggling Toronto rotation.
- Brandon Valenzuela (Home Run: 11¢ Yes): Valenzuela's price is modest but still reflects some upside in a lineup this hot.
- Isaac Collins (Home Run: 11¢ Yes): Collins ties Valenzuela at 11¢ as a lower-probability piece on this board.
- John Rave (Home Run: 11¢ Yes): Rave rounds out the four-way tie at 11¢ among Kansas City's depth bats.
- Vladimir Guerrero Jr. (Home Run: 11¢ Yes, 94¢ No): Guerrero is Toronto's best answer on this board, and even at 11¢ he's the highest-priced Blue Jays hitter in the home run market tonight.
Giants vs Reds: Best MLB Player Props Today
San Francisco (53-78) snapped a four-game losing streak by shutting out Cincinnati (62-70) 5-0 on Monday, with Rafael Devers hitting a three-run homer in the win.
Giants starter Adrian Houser and Reds starter Brady Singer both headline the strikeout board tonight, but this section sticks to home run pricing for Giants vs Reds.
Moneyline
- Cincinnati Reds (49¢, implying 49%): the Reds have been shut out 14 times this season, tied for the most in the majors, and that shows up in a moneyline that isn't giving them much of an edge on the road.
- San Francisco Giants (52¢, implying 52%): San Francisco is a modest favorite off Monday's shutout win, even with a Giants team on pace for triple-digit losses.
Spread and Total
- Reds -1.5 (38¢) / Giants +1.5 (63¢): the market thinks San Francisco is the safer side to cover here, even without laying the moneyline juice.
- Over 7.5 (51¢) / Under 7.5 (50¢): the total is a virtual coin flip between two offenses that have both struggled to score consistently this season.
Home Runs
These home run props for Giants vs Reds are ranked below by Yes price, from most to least likely on the board.
- Rafael Devers (Home Run: 19¢ Yes, 99¢ No): Devers is chasing his fourth career 30-homer season and just hit a three-run shot Monday, making him the clear top price on this board.
- Elly De La Cruz (Home Run: 12¢ Yes, 99¢ No): De La Cruz's power-speed profile keeps him well above most of the Reds lineup even during a 3-7 stretch over the last ten games.
- JJ Bleday (Home Run: 12¢ Yes, 99¢ No): Bleday matches De La Cruz at 12¢ as one of the Giants' better secondary power threats.
- Eugenio Suárez (Home Run: 11¢ Yes, 99¢ No): Suárez remains a legitimate pop threat for Cincinnati even as the offense has gone cold as a whole.
- Héctor Rodríguez (Home Run: 9.7¢ Yes, 99.0¢ No): Rodríguez gets a modest price as a depth piece in the Giants' lineup.
- Grant McCray (Home Run: 9¢ Yes, 99¢ No): McCray's speed-first game keeps his home run price on the lower end of San Francisco's regulars.
- Tyler Stephenson (Home Run: 8.8¢ Yes, 99.0¢ No): Stephenson's price reflects a Reds offense that has been shut out 14 times this season.
- Drew Gilbert (Home Run: 8¢ Yes, 99¢ No): Gilbert is priced as a longer shot in the Giants' outfield mix.
- Sal Stewart (Home Run: 8¢ Yes, 99¢ No): Stewart ties Gilbert at 8¢ as one of the lower-probability Reds bats on the board.
- Shay Whitcomb (Home Run: 8¢ Yes, 99¢ No): Whitcomb rounds out the top ten at 8¢, closing out a board where every Under price sits at 99¢, underscoring just how unlikely the market thinks a home run is from either side's bottom of the order tonight.
Beyond these three games, Polymarket has home run, strikeout, and main-market contracts priced across the rest of tonight's full MLB slate.

MLB Player Props Today: Final Thoughts
Across all three games, the board tells a fairly consistent story: pitching matchups are driving the home run pricing more than raw power rankings.
Scherzer's 7.40 ERA is why the Royals' home run market is so heavily inflated in Blue Jays vs Royals, and Houston's bullpen troubles are doing the same work in Yankees vs Astros.
Giants vs Reds is the outlier, a low-scoring matchup where even the best home run price on the board sits under 20¢, and you can dig deeper into that pattern with a quick look at the full Polymarket promo codes page before placing anything tonight.
