Best MLB Parlay Picks Today (Take Tigers as Road Dog, Reds Auto-Fade Rolls On vs. Pirates)

It's a massive Saturday slate of baseball, filled with doubleheaders galore and plenty of opportunities to string multiple bets together.

In today's edition of "Best MLB Parlay Picks Today," I like two struggling road teams to get it done; one on the moneyline and another on the run line.

Don't forget, while parlays are a ton of fun to bet, it's worthwhile to note that they are not the way to become a profitable sports bettor.

Let's get into the picks, with all odds via WynnBET.

Best MLB Parlay Picks for Saturday, May 7 (+508 Odds)

• Detroit Tigers Moneyline +170
• Pittsburgh Pirates Run Line -1.5 (+125)

Detroit Tigers +170 vs. Houston Astros

Earlier today, I wrote how the Tigers and Astros are likely to play to the under, as two talented left-handers match up in Framber Valdez vs Eduardo Rodriguez. Rodriguez has been the beneficiary of some tough luck in the early going, given his ERA of 5.33 is much higher than his fielder independent pitching (FIP) of 3.75. He also had his best control of the season in his last start vs. a tough L.A. Dodgers team; going 5.1 innings without recording a walk.

Valdez is a bit of the opposite, with a higher FIP than ERA, while also seeing his walk rate soar to almost five per nine innings.

Houston's the better team, but Detroit have a lot of good hitters from the right side to help neutralize Valdez, and the fact that his strikeout rate is way down provides another boost to the underdog Tigers.

Pittsburgh Pirates Run Line -1.5 (+125)

Perhaps you're getting sick of us at BetSided continue to fade the Reds, but for a team that has just three wins through May 7, including a run line record of 6-19-0, you have to keep doing it!

In the late game of their doubleheader, they're sending out Robert Dugger, claimed off of waivers just three days ago from the Tampa Bay Rays.

He's opposed by Mitch Keller, a heavy ground-ball pitcher who's had some bad luck that's about to turn his way. Keller is 0-4 in five starts this year with a 5.32 ERA, but his expected ERA (xERA) is actually 2.66 over at Fangraphs. Despite four losses to his name, he's still a positive 0.3 WAR pitcher, meaning he's 0.3 wins above the traditional replacement level player.

If Keller finally gets the run support he deserves, along with some better fielding, I don't expect this game to be close at all.
