MLB Sunday three-team mega parlay (+1667 odds): Tigers to pull big upset

We are approaching the home stretch of the 2021 MLB season and we now know more or less where things stand. We don’t have many days of regular-season baseball left, so why not try to go for a big payday? That’s right; we’re back with another MLB mega parlay, this time a 3-teamer with a payout north of 16/1, and we’re counting on the Tigers to pull off a big upset of the Rays.

We’re absolutely on fire with these mega parlays. My colleague John Hyslop just cashed the mega parlay on Monday at 11/1 odds, and then I did it on Wednesday at 13/1. Then, Ricky Dimon did it again on Saturday at 12/1. We’re going big and bold, so let’s not waste any more time. But before we dive in, don’t forget to check out our picks for the side and total on every MLB game, with our team of experts in red-hot form.

Colorado Rockies -1.5 (+175)

Detroit Tigers ML (+265)

Houston Astros -1.5 (-130)

Parlay odds: +1667

Let’s break down each of the legs one by one.

Colorado Rockies -1.5 (+175) over Washington Nationals

The Rockies being underestimated by oddsmakers? Must be a day ending in Y. Colorado has been playing really well recently, but as usual nobody seems to be paying attention. They’ve won 7 of their past 8 games, and just clobbered Washington 6-0 on Saturday. Washington is clearly just playing out the string and waiting for the season to end.

Over the past month and a half, the Nationals have gone a pitiful 11-32. It makes no sense for them to be a favorite here. Especially not with Paolo Espino on the mound. Espino is 34, yet had only 14 career big-league appearances under his belt before this season. There’s a reason why. He’s been awful the last couple months, and the Nats are just 1-7 the last eight times he’s taken the mound.

Detroit Tigers ML (+265) over Tampa Bay Rays

Unlike the Nationals, the Tigers are actually playing with some pride down the stretch. Detroit is 6-3 in their last 9 games, and they beat Tampa on Saturday. Getting nearly 3/1 is just too good to pass up, especially considering there’s no huge mismatch on the mound. Rays starter Shan McClanahan actually has a higher ERA and WHIP this season than Tigers starter Wily Peralta.

McClanahan is a rookie, and his 1.30 WHIP shows that he’s lucky his 3.59 ERA isn’t higher than it is. The Rays are just 4-6 in their last 10, so I’m certainly not too scared of them. Peralta has been a really pleasant surprise this season, and he’s coming off an outing in which he tossed 6 shutout innings against the Brewers and gave up only 2 hits. He’s capable of pitching well enough to deliver a win.

Houston Astros -1.5 (-145) over Arizona Diamondbacks

We’ll wrap up this mega parlay with the Astros on the run line. Houston surprisingly lost on Saturday, and I think they’ll be extra motivated to bounce back and pour it on against lowly Arizona. The Diamondbacks are arguably the worst team in the league, and they’re just 20-57 on the road this year.

Arizona will start Zac Gallen, who has been something of a bad luck charm for the team. Incredibly, the team is just 2-15 in his last 17 starts. Houston will have Zack Greinke here pitching against his old team, and they obviously have one of the most talented offenses in MLB. Even after two tough starts in a row, Greinke still has a very solid 1.17 WHIP on the year.
