Sunday's massive 14-game Major League Baseball slate is loaded with parlay value. Here are our top combinations for September 20.
Sunday's Best Major League Baseball Parlay Picks - September 20, 2026
A monster 14-game Major League Baseball Sunday slate gives us plenty of angles to work with. From an afternoon full of divisional battles to a primetime showdown in Baltimore, we've combed through the lines to find the best parlay value of the day. Let's get into it.
Line Movement and Value Spots
A few lines jumped out immediately as worth targeting. The Detroit Tigers at +102 (Courtside) on the moneyline against the Chicago White Sox is borderline laughable - the Tigers are fighting for postseason position while the White Sox have been one of the worst teams in baseball. Getting a legitimate playoff contender at plus money against a basement dweller screams value. Similarly, Atlanta Braves +120 (Courtside) against the Houston Astros in Houston is an interesting spot - the Braves are capable of putting up big offensive numbers and catching the Astros on a lazy Sunday afternoon in a potential lookahead spot.
The Baltimore Orioles +180 (BetRivers) at home against the Milwaukee Brewers is the most eye-catching number on the board. The Orioles at home at that price represents enormous value if they're not completely out of the picture, and Milwaukee at -200 is the kind of chalk that can burn you in baseball's variance-heavy landscape.
Parlay 1: The Value Hammer (3-Leg)
This parlay targets two flat-out value moneylines plus a spread play that looks extremely well-priced.
- Detroit Tigers ML (+102, Courtside) - Getting a playoff-hopeful Tigers squad at plus money on the road against the woeful Chicago White Sox is one of the best values on today's board. The White Sox have been historically bad in 2026 and this line should be flipped.
- New York Yankees -1.5 (+150, theScore Bet) - The Yankees running out a strong rotation arm on a Sunday nationally visible spot, and +150 on the run line is exceptional value for a club with this kind of offensive upside. Arizona has been inconsistent at home and New York's lineup can put crooked numbers on the board.
- Seattle Mariners -1.5 (-105, BetMGM) - The Mariners are built around elite pitching and shutting down opponents. Coors Field or not, Seattle's rotation has the ceiling to dominate and -105 on the run line for a top-tier pitching staff is solid value. The Rockies have been the worst team in the National League and this line feels light.
Combined odds: approximately +571 - A $20 bet returns over $114 in profit.
Parlay 2: The Spread Parlay (3-Leg)
This combination leans into the spread market with three teams that should cover comfortably based on the matchup context.
- Cleveland Guardians -1.5 (+104, FanDuel) - The Guardians at plus money on the run line at home against the Athletics is a gift. Cleveland is one of the American League's most consistent clubs and the A's remain a rebuilding project. The Guardians have the pitching and lineup depth to win this game by multiple runs.
- Chicago Cubs -1.5 (+105, theScore Bet) - The Cubs at plus money on the run line against a Cincinnati Reds team that has struggled all season is excellent value. Chicago has enough offensive firepower to win convincingly, and +105 on a -1.5 spread for the favourite is a line we want to be on.
- Milwaukee Brewers -1.5 (-115, BetMGM) - Yes, -115 on the run line isn't as juicy as the other two legs, but Milwaukee's pitching staff is elite and a primetime Sunday road game in Baltimore - even at a challenging venue - sets up well for a Brewers club that knows how to manufacture runs and win games convincingly.
Combined odds: approximately +419 - A $20 bet returns over $83 in profit.
Parlay 3: The Totals Special (2-Leg)
For bettors who prefer totals, this two-leg combination targets two matchups with clear over/under angles.
- Athletics vs Cleveland Guardians - Over 7.5 (+110, theScore Bet) - The total is the lowest on the entire board at 7.5, and getting plus money on the over here is excellent value. Even in a pitcher's duel, eight combined runs between two Major League Baseball lineups is a very reachable number and +110 means the books are offering us value on this outcome.
- Chicago Cubs vs Cincinnati Reds - Under 9.5 (+105, theScore Bet) - A total set above nine and a half runs is asking a lot in a regular-season September game. Getting plus money on the under at 9.5 is rare and worth targeting - most games settle well short of double digits, and even if both offences show up, clearing 10 runs combined is not a given.
Combined odds: approximately +330 - A $20 bet returns over $66 in profit.
Key Value Flags
- Baltimore Orioles +180 (BetRivers) - The largest underdog price on the board at home. If the Orioles are competitive, this is massive value.
- Detroit Tigers +102 (Courtside) - Playoff-calibre team at plus money against the White Sox. One of the best value spots of the day.
- New York Yankees -1.5 +150 (theScore Bet) - Run line plus money for the Yankees in a winnable spot is exceptional pricing.
- Cleveland Guardians -1.5 +104 (FanDuel) - Another run line at plus money for a clear favourite - these are the lines to target in baseball parlays.
