Best MLB Parlay Picks Today (Two Favorites, Two Underdogs & One Total Ready for Wild Ride)

When you ride a roller coaster, the calmest parts precede the most wild. So giddy up, because the last couple days of my parlay picks have not gone very well. That can only mean one thing: we're about to cause havoc for sportsbooks.

We've got a fantastic 14-game MLB slate with tons of day games. There's value sprinkled all throughout the day, so be sure to check out the BetSided team previews for each matchup.

I've identified my favorite wagers on the slate though, and it's time to enjoy the ride. Using odds from WynnBET Sportsbook, here are my favorite MLB parlay picks of the day:

Best MLB Parlay Picks Today

Rangers (-119) vs Mariners

Let's get things started with fading a prime candidate for negative regression, Marco Gonzales, who has a 5.18 ERA this month. Seattle is 1-5 in Gonzales' last six home starts as he ranks in the 10th percentile in expected batting average and a disastrous first percentile in strikeout percentage.

Jon Gray, meanwhile, has been one of AL's best pitchers over the last two months. Texas won seven of his last eight starts as he's limited his opponent to three runs or fewer in each outing. In fact, Gray allowed the same number of runs over his last eight starts that Gonzales did in his last two.

Texas mashes left-handed pitching and the Mariners have lost seven of eight as a home underdog. Take the value on Gray in this battle between pitchers going in opposite directions.

Marlins vs Reds Under 8.0 (+105)

This is an under-the-radar excellent pitching matchup with Braxton Garrett taking on Luis Castillo in what is likely his final start as a Red. I see tremendous value on the under, especially at plus odds.

Castillo has a 1.00 ERA over his last four starts as it's clear he wants to get far away from Cincinnati and is doing his best to earn the attention of a contender. The under is 9-3 in his last dozen outings and Castillo has a great matchup against a Marlins' lineup that ranks 27th in OPS against right-handed pitchers this month.

Garrett has nearly been as good as Castillo and he's improving with every start. Over his last two, Garrett allowed just four hits and one run over 12 innings while striking out 18 batters. Cincy struggles against left-handed pitchers, and the under is 7-2 in Garrett's last nine appearances.

I'll happily take the under at plus odds with these two stellar pitchers squaring off.

Orioles (-101) vs Rays

Tyler Wells pitches, so I'm backing Baltimore as a home underdog. The Orioles are 8-2 in Wells' last 10 starts, covering the run line every single time, and are 5-2 in their last seven as home 'dogs.

Tampa Bay, meanwhile, is 1-7 in its last eight as a road favorite. Drew Rasmussen is due for a poor outing as well. He's had a worse expected ERA than actual ERA in five of his last six starts, and his 4.21 expected ERA on the season is a full run worse than his 3.13 actual ERA.

Baltimore rakes at home and I love the value for them to hand Tampa a fifth-straight loss.

Blue Jays (-245) vs Cardinals

These clubs are going in opposite directions and I expect Toronto to roll today. Kevin Gausman is due for a strong outing. His 1.99 FIP (Fielding Independent Pitching) leads all MLB pitchers, but his 3.00 ERA is lagging behind. He should have that strong outing today against a Cardinals' lineup missing Nolan Arenado and Paul Goldschmidt due to vaccination status.

St. Louis has lost 14 of 17 as road underdogs and send Adam Wainwright to the bump, who has been quite lucky. He's got a 4.48 expected ERA compared to a 3.40 actual ERA and has struggled on the road.

Look for the Blue Jays to pick up an eighth straight win as the Cardinals continue to stumble.

Guardians (+116) vs Red Sox

My man Peter Dewey is on the money with this one. We're rolling with my beloved Cleveland Guardians tonight with Stanford man Cal Quantrill facing off against Nathan Eovaldi in his third start since returning from the Injured List.

Those first two starts didn't go well for Eovaldi. He gave up a dozen runs in just seven innings, compiling a 15.43 ERA. I see no reason to trust Eovaldi, who ranks in the third percentile in average exit velocity on the season, or the Red Sox, who are 2-6 in their last eight as a favorite.

I do, however, see reason to trust Quantrill. He's quietly been one of the most consistently great pitchers in MLB over the last calendar year, ingratiating himself with a stellar list of names here. Quantrill allowed three or fewer runs in 15 of his 18 outings this year and should find success against a Red Sox lineup that ranks 24th in OPS against right-handed pitchers in July.

Cleveland is 8-4 in its last dozen as a road favorite. Trust the Guardians to hand Boston its 11th loss in 13 games as Eovaldi falters and Quantrill remains steady.

MLB Parlay for July 27, 2022

The "Giddy Up" Parlay (+2184)

• Rangers (-119) vs Mariners

• Marlins vs Reds Under 8.0 (+105)

• Orioles (-101) vs Rays

• Blue Jays (-245) vs Cardinals

• Guardians (+116) vs Red Sox

We're back to swinging for the fences. This rollercoaster is ready for a wild ride, so get yourself ready. Odds of +2184 give a $25 bettor a profit of $545.91, so maybe we'll all build our own rollercoasters by the end of it.

If you're not feeling quite so rambunctious, the Rangers and Marlins vs Reds Under are my two favorite plays. Combining those still gives you odds of +277 at WynnBET, which is pretty wonderful in its own right.

Best of luck with whichever direction you choose. Let's get after it! Giddy up, baby.
