A massive 15-game Tuesday MLB slate is loaded with parlay value. Here are our best combinations with boosted odds across tonight's games.
Tuesday Major League Baseball Parlay Picks - May 19, 2026
Fifteen games on the Tuesday Major League Baseball slate means plenty of angles to attack, and tonight's card is full of intriguing pitching matchups, run-line value, and totals that the market hasn't quite priced perfectly. We've combed through the live odds across all the major books to bring you three parlay combinations worth targeting tonight.
Key Matchups and Analysis
Baltimore Orioles @ Tampa Bay Rays - 7:41 PM ET
This is one of the most interesting lines on the board tonight. The Orioles are getting +105 on the moneyline at BetMGM - that's essentially a pick-em price for a Baltimore club that has genuine postseason pedigree. Tampa Bay at home is always a tricky proposition, but laying -116 on the Rays in what figures to be a tight, low-scoring affair feels like an overreaction. The total sitting at 7.5 reflects a genuine pitchers' duel setup. With the run line priced at +175 for Baltimore to win by 2+, the straight moneyline at plus-money is exceptional value. This is our top value flag of the night - the market is essentially saying Baltimore and Tampa are dead even, yet you can back the Orioles at a profit. Grab it.
New York Mets @ Washington Nationals - 7:46 PM ET
The Mets head to D.C. as firm favourites at -149, which makes their run line at +110 (theScore Bet) an outstanding value proposition. New York winning by 2+ at plus-money against a Nationals side that has struggled for consistency this season is a line that deserves attention. Washington at +136 (FanDuel) is tempting on paper, but the talent gap here is too wide to back the home side. The total at 9 suggests a moderate-scoring game - not a blowout, but enough run production for the Mets to cover comfortably.
Seattle Mariners @ Chicago White Sox - 10:41 PM ET
The Mariners have one of the better pitching setups in the American League and are installed as -145 home favourites. Their run line at +145 (theScore Bet) to win by 2+ is outstanding value given the White Sox's offensive struggles this season. The total is a low 7.5, which speaks to the pitching quality Seattle is expected to bring. A clean Mariners cover at better than even money is one of the best spread opportunities on tonight's card.
Los Angeles Dodgers @ San Diego Padres - 10:41 PM ET
The Dodgers are -154 favourites on the moneyline, which is steep - but their run line at +106 (Bally Bet) to win by 2+ is remarkably generous. Los Angeles carries one of the most powerful lineups in baseball, and the Padres, while competitive at home, are facing a Dodgers team with elite pitching depth. The total at 8.5 is a neutral look, but the run-line value here is too good to ignore in parlay construction.
Texas Rangers @ Colorado Rockies - 9:41 PM ET
Coors Field. Total posted at 10.5 with the over at -115 (BetMGM). This is the simplest bet on the entire slate. The Rockies' home ballpark is notorious for inflating run totals, and the Rangers have enough offensive pop to contribute. With both clubs capable of giving up runs at altitude, Over 10.5 at BetMGM is a natural parlay inclusion. It takes a combined shutout performance for this to miss, which is almost unheard of at Coors.
Parlay 1 - The Value Bomb (3-Leg)
This combination stacks three spread-value picks that all offer plus-money or near-even pricing individually, creating a powerful combined ticket.
- Baltimore Orioles ML (+105) - BetMGM - Plus-money on a legitimate team
- New York Mets -1.5 (+110) - theScore Bet - Mets cover against a weak Nationals side
- Seattle Mariners -1.5 (+145) - theScore Bet - Mariners dominate a struggling White Sox lineup
Combined Parlay Odds: approximately +487 - A $100 bet returns $587 total.
Parlay 2 - Run Line Power Combo (3-Leg)
Targeting plus-money run lines on clear favourites, with a high-altitude over thrown in for firepower.
- Los Angeles Dodgers -1.5 (+106) - Bally Bet - Dodgers too good to not cover at Petco
- Texas Rangers/Colorado Rockies Over 10.5 (-115) - BetMGM - Coors Field does the heavy lifting
- Seattle Mariners -1.5 (+145) - theScore Bet - Mariners run line value too good to pass up
Combined Parlay Odds: approximately +418 - A $100 bet returns $518 total.
Parlay 3 - The Two-Leg Value Play
For bettors who prefer a tighter, higher-probability parlay, this two-legger keeps it clean with two strong spread plays.
- Baltimore Orioles ML (+105) - BetMGM - Best value flag on the entire slate
- New York Mets -1.5 (+110) - theScore Bet - Mets flexing their superiority vs Washington
Combined Parlay Odds: approximately +331 - A $100 bet returns $431 total.
Value Flag of the Night
The Baltimore Orioles at +105 ML (BetMGM) is the single best-priced bet on tonight's board. Getting plus-money on a legitimate, well-constructed Major League Baseball franchise against Tampa Bay - a team with real offensive limitations - is a market inefficiency worth exploiting. Even as a standalone single, this deserves action tonight.
