Wait 5 sec.

The Atlanta Braves kick off Monday’s small slate of games with a divisional matchup against the Washington Nationals.Even though the Atlanta Braves have won their last eight games in a row, time is not on their side as they are still seven games back from the New York Mets for the last wildcard spot in the playoffs. Luckily for Atlanta, they will have the opportunity to keep their postseason hopes alive on Monday night as they face off against the Washington Nationals, who severely underwhelm on offense.While there are only three games taking place on Monday night, there are still plenty of markets to browse through, which you can read a detailed breakdown of below.Best betting promos and sportsbooks for today’s MLB Prop BetsFind the best promos and sportsbooks to use for today’s Major League Baseball prop bets.Washington Nationals vs Atlanta Braves (7:15pm, EST)Chris Sale Over 8.5 Strikeouts (-132) at FanDuel SportsbookEven though Atlanta severely underwhelmed this year per their preseason projections, their low level of play did not affect Chris Sale as the Braves ace is currently averaging an ERA of 2.35, a WHIP of 1.070, and a FIP of 2.49. His aggression on the mound has played a major role in his success this season, as Sale is also averaging more than one Strikeout per Inning Pitched.In a divisional matchup against Washington, Sale will have a great opportunity to generate another high volume of Strikeouts as he faces off against a Nationals offense that ranks below league average in Contact Rate and in on-base percentage. For some more exposure, escalator bet Sale’s Strikeout prop by placing smaller wagers on his alternate overs at the best available odds.Washington Nationals First Five Innings Team Total Under 1.5 (-175) at BetMGM SportsbookThe Nationals’ struggles with making contact also hurt their ability to bring home their runners, as their offense ranks in the bottom half of the board in RBIs and in Total Runs Scored. With the Braves’ defense reducing the amount of variance with their coverage, as their top-3 mark in Fielding Percentage indicates, expect Sale to hold the Nationals out of scoring position in the first five innings of the contest.Milwaukee Brewers vs San Diego Padres (9:40pm, EST)Freddy Peralta Under 1.5 Earned Runs (+120) at BetMGM SportsbookLike Sale, Freddy Peralta has managed to put together a very productive 2025 campaign as the Milwaukee Brewers pitcher heads into Monday night averaging an ERA of 2.65, a WHIP of 1.073, and a FIP of 3.61. Peralta’s ability to avoid contact at a consistent rate has helped him keep opposing runners off the bases, as he also averages less than one Hit Allowed per Inning Pitched.Peralta will have a great opportunity to sustain his high level of play on the mound against San Diego as he faces off against a Padres offense that ranks below league average in Slugger Percentage and in Total Runs Scored. Especially with his back end shortening the gaps in the outfield with their high level of play on defense, as the Brewers rank top-10 in Defensive Efficiency.Elias Diaz Under 0.5 Hit (-150) at BetMGM SportsbookSince the start of the regular season, Elias Diaz has struggled to find his footing as the Padres batter is averaging less than 0.5 Hit per game and a .203 Batting Average. With Peralta possessing an elite blend of power and accuracy, as well as being surrounded by a productive defense, expect Diaz to continue to struggle at the plate and be held without a Hit.St. Louis Cardinals vs San Francisco Giants (9:45pm, EST)Justin Verlander Over 17.5 Outs (-167) at FanDuel SportsbookEven in his twilight years, Justin Verlander is still playing at a high level as the San Francisco Giants pitcher is averaging an ERA of 3.75 and less than one Hit Against per Inning Pitched. Even with his defense ranking 27th in Defensive Efficiency, Verlander is able to succeed as he also averages a FIP of 3.71.Fortunately for Verlander, he will be able to neutralize the St. Louis Cardinals offense with just his individual production as he faces off against a lineup that ranks below league average in Team Total Hits and in Slugger Percentage. Should the total on Verlander’s Outs prop cross through the key number of 18, then pass on this market.About the authorKody MalstromKody Malstrom is a professional sports bettor and sports betting journalist with six years of experience covering a vast majority of sports.
