Now that we've had an extended weekend to catch our breath and recalibrate for the summer, it's time to nail a MLB parlay.

We've got a loaded slate today with poor weather across the country, some terrible pitching matchups and a couple of good ones. As always, our team at BetSided is analyzing every angle to bring you the best values each day, so be sure to check out the previews from everyone before you fill out your bet slips at WynnBET Sportsbook.

As we get set to turn the calendar over to June, I'm ready to bring us one more lovely May cash. It's pouring rain here in Kansas City right now, but it'll be raining dollars by the time the day ends.

Without further ado, here are my best MLB parlay picks to close out the month using the odds from WynnBET:

Best MLB Parlay Picks for Tuesday, May 31

Giants (+115) vs Phillies

The Phillies have lost four straight thanks to an atrocious stretch from their bullpen, and I like the Giants to extend their losing streak today. Ranger Suarez has struggled of late with a 7.02 ERA in his last three starts. He walked four batters in his last outing and faces a San Francisco lineup that matches up well. They're second in OPS against left-handed pitchers in May and average the second-most walks per game in the league.

On the other end, Jakob Junis has a 1.69 ERA on the road and has given up more than two runs only once in six appearances. He has elite command and has shown a greater ability to go deep in games than Suarez has, alleviating the pressure on the Giants' bullpen.

In their last six games as a home favorite, the Phillies are a pathetic 1-5. Their streak of futility continues today as San Francisco wins their third straight.

Red Sox (-137) vs Reds

Boston has won six straight games that Michael Wacha started and should make it seven in-a-row today. Luis Castillo has had a fine month, but he doesn't go deep in games and his last three starts have come against teams that rank 27th, 26th, and 25th in OPS this month.

The Red Sox lineup should tee off on Castillo, as they're second in OPS in May and have been one of the best in the sport. Look for Boston to improve to 10-4 in their last 14 while the Reds fall to 4-17 in their last 21 as a road underdog.

Mets (-185) vs Nationals

There's no denying how flaming hot the Mets lineup is. They're averaging an obscene 8.86 runs per game in the last week and get to face one of the worst starters in all of baseball today. That's right, it's Patrick Corbin day!

Try not to shield your eyes from the horror and take a peak at Corbin's MLB Statcast pitching profile from Baseball Savant:

This will be the third time the Mets have seen Corbin already this year and they should take advantage of his 6.86 road ERA. Washington is 1-9 in Corbin's 10 starts and the Mets have won five straight as a home favorite. Trust New York to notch another victory today as they celebrate Patrick Corbin day.

Rangers (-114) vs Rays

I have to disagree with Reed Wallach and back the Rangers in this one. They're 9-3 in their last dozen home games, including five straight wins, and have their ace Martin Perez on the mound today. In his last seven starts, Perez has a 0.75 ERA and notched a quality start each time. He should be among the favorites for the Cy Young award and is the early leader in the clubhouse for "Best Offseason Acquisition."

Ryan Yarbrough is having a fine year for Tampa Bay as well, but he doesn't pitch deep into games and the Rays' bullpen was exhausted yesterday after a short outing from Drew Rasmussen. He has a 4.76 ERA on the road. Tampa Bay has lost three straight Yarbrough starts while the Rangers have won five in a row when Perez pitches. Back Texas to improve to 10-3 in their last 13 at home.

Astros vs Athletics Under 6.5 (+100)

If it's a day ending in "Y" and the Astros are playing, we take the under and don't ask any questions. It's 11-1 in Houston's last dozen games and 37-12 on the season.

Cristian Javier ranks in the 90th percentile in expected batting average and should find success against an Oakland lineup that ranks dead last in OPS against right-handed pitchers this month. Frankie Montas has been excellent as well, compiling a 2.25 ERA in five May starts.

The under is 5-1 in Javier's last six outings and 7-2 in Montas' last nine. Expect these trends to continue behind the surest bet in MLB.

Braves vs Diamondbacks Over 9.0 (-115)

Speaking of sure things, the over is 8-1 in Charlie Morton's starts and I like it to improve to 9-1 today. Both Morton and Humberto Castellanos have terrible underlying metrics and face difficult lineups. Castellanos has given up six home runs in his last four starts while Morton has surrendered one in each of his last two.

Well, the Braves and Diamondbacks happen to rank fifth and sixth in home runs per game, with two of the hottest lineups in baseball.

Arizona has the fourth-highest OPS against right-handed pitchers in May while the Braves are 10th over the last two weeks. With a subpar pitching matchup and explosive lineups, back the over to improve to 11-3-1 in Atlanta's last 15 as a favorite.

Recap

The "It's Raining Dollars" Parlay (+3921)

  • Giants (+115) vs Phillies
  • Red Sox (-137) vs Reds
  • Mets (-185) vs Nationals
  • Rangers (-114) vs Rays
  • Astros vs Athletics Under 6.5 (+100)
  • Braves vs Diamondbacks Over 9.0 (-115)

Three favorites, two totals and an underdog? I didn't major in math, but I'm pretty sure that equals dollars. Many, many dollars.

I'm fired up to end May with a bang, though I encourage you to mix-and-match while creating your own parlay over at WynnBET.

Go ahead and get your umbrellas out. To loosely paraphrase the great Randy Moss, I hear it's cloudy with a chance of straight cash, homie.
