⚾ Red Sox vs. Cardinals Prediction & Picks: MLB Odds for Saturday, April 11

Fresh off their first series win of the season, the Boston Red Sox look to get back on track after dropping the first game of the three-game set to the St. Louis Cardinals. This clash of two of MLB’s most storied franchises features a pitching matchup between Ranger Suarez and Kyle Leahy, with first pitch from Busch Stadium in St. Louis set for 7:15 p.m. ET (FOX). The Red Sox are a -140 betting favorite.

My Red Sox vs. Cardinals prediction finds value with the home underdogs given last year's season-long success against left-handed pitchers. Adding to my MLB picks, I am following the trends of Trevor Story's cold start and Jordan Walker's resurgent season to comprise my top player prop and home run wager for this interleague matchup.

🏆 Who will win Red Sox vs. Cardinals?

St. Louis won its first two home series of the season, while Boston is just 1-5 on the road. I expect the Red Sox’ road struggles to continue against a Cardinals team that had great success against southpaws last year.

Score prediction: Cardinals 5, Red Sox 4

💰 Red Sox vs. Cardinals prediction & best bet

Cardinals ML (+120)

For those looking for optimism surrounding the poor beginning to Ranger Suarez’s Red Sox career, the southpaw also struggled through his first two starts last year. Suarez pitched to a 5.91 ERA and 1.92 FIP in 10 2/3 innings in his first two starts, then rebounded for a 3.01 ERA and 3.31 FIP over 146 2/3 innings the rest of the season.

However, I am buying that despite St. Louis’ overall disappointing 78-84 record, it ranked fifth in BABIP and in the top-11 in on-base percentage and strikeout rate against left-handed pitching last year.  

🔥 Best Red Sox vs. Cardinals player prop bet

Trevor Story Under 1.5 total bases (-150)

Entering this series there were four players among 186 qualified hitters than had a negative wRC+ so far this season, and two of them resided in the Red Sox lineup (Caleb Durbin and Trevor Story).

Story in theory has a great matchup against Cardinals righty Kyle Leahy, who ranks in the 20th percentile or worse in hard-hit rate, barrels, xERA, and xBA. But the free-swinging shortstop is also on pace for a career-high strikeout rate and hasn’t drawn a walk this season, which are big reasons for his paltry .169 wOBA.

Just three of Story’s eight hits on the season have gone for extra bases, and his 37.5% strikeout rate against righties entering the series makes this Under a great value play.

💣 Red Sox vs. Cardinals home run prediction

Jordan Walker to hit a home run (+770)

In 2024, Jordan Walker hit just five home runs with a 72 OPS+ in 51 games, and followed that up with six home runs and a 66 OPS+ in 111 games last season. 

Some may think this year’s start is unsustainable, but Walker’s five home runs through the first 12 games were tied for the MLB lead, while his 1.049 OPS ranked eighth among all hitters.

Suarez has already served up two long balls in 8 1/3 innings, with a .357/.419/.500 slash line to right-handed hitters. 

After hitting just one home run and striking out 16 times in 44 Spring Training at-bats, I am riding the hot hand and expecting Walker to tie his home run total from a season ago.

🚀 Red Sox vs. Cardinals same-game parlay

If the Cardinals are going to pull the upset as home underdogs, they'll likely have to continue to limit Trevor Story at the plate, while continuing to get production from Jordan Walker. I'm giving myself more of a chance to cash this three-leg parlay by backing Walker's RBI prop instead of expecting him to hit a home run. He has overcome a 3:1 K:BB ratio entering the series by belting nearly a third of the team's home runs and being one of two Cardinals hitters with 10-plus RBIs.

💡 How I'm betting Red Sox vs. Cardinals: MLB strategy

Follow all of our MLB analysis and expert predictions for baseball season.

Out of fear that I'm catching Jordan Walker after his torrid stretch at the plate is over, I am allocating just 0.25 units of my bankroll to his home run prop.  

We're also getting a fair price (+120) to back St. Louis to clinch a series victory today, but there is also value in the Cardinals' +1.5 runline odds at -140 at Caesars and bet365. I'd pass on the steeper -150 and -154 odds at BetMGM and FanDuel, respectively.

Those that think Story's -150 odds (carrying a 60% implied probability) for the Under on 1.5 total bases are too steep could look into him going hitless at the best odds of +200 at bet365.

📊 Live Red Sox vs. Cardinals odds

Boston ranges from a -138 to -145 betting favorite, but St. Louis is thus far the only underdog on the entire Saturday MLB slate attracting the majority of the early wagers (55%). The line hasn't budged much at the best sports betting apps, but if the line starts to shade towards the Red Sox despite these betting splits, that would signal reverse line movement, with sharp action coming in on the favorites.

FanDuel is the only sportsbook that differs from the rest of the market with a total of 7.5 runs (juiced -122 to the Over), while the others are all at an O/U of 8.0. Most have the standard -110 juice on either side of the total, suggesting that they're comfortable with that line. Therefore, it should only be a matter of time before FanDuel aligns with the rest of the market and ticks up to 8.0.
