MLB Best Bet Parlay For Monday, September 18

Monday MLB Parlay Analysis

New York Mets vs Miami Marlins, 6:41 PM ET

LEG 1: Luis Arraez 1+ Hit (-310) with FanDuel

The first leg of this hit parlay is one of the best hitters in baseball, Luis Arraez. Arraez takes on Butto and the Mets today at home.

The Marlins are still in must-win mode and I expect the offense to be there against Butto. Arraez has been smoking righties this month and Butto should be no exception.

In September, Arraez is hitting .408 vs righties. Arraez hits better at home as well, so he all around has an ideal matchup today. 

Arraez enters this game with 8 total hits in his last 3 games. Today we only need 1 hit and I think he should deliver once again for the community!


Philadelphia Phillies vs Atlanta Braves, 7:21 PM ET

LEG 2: Trea Turner 1+ Hit (-380) with FanDuel

Our COS Hall of Famer Trea Turner is counted upon once again for this parlay. Trea and the Phillies head to Atlanta to take on the Braves. 

Trea has been ridiculously hot recently. In September, Trea is hitting an insane .367. 

Today he faces Kyle Wright. Wright is a righty and that bodes well for Trea since he’s smoking righties this month.

In September, Trea is hitting .395 vs righties. Getting nine innings of at-bats in the two spot, Trea should once again be able to come through for us.

Seattle Mariners vs Oakland Athletics, 9:41 PM ET

LEG 3: J.P. Crawford1+ Hit (-230) with FanDuel

The last leg of this hit parlay sends us to Oakland where the Mariners face off against the A’s. In a must win game for Seattle, we’re needing a hit from J.P. Crawford.

While Crawford isn’t normally a guy we see in hit parlays, his matchup is great today. Crawford faces the lefty JP Sears.

Against lefties, Sears allows a .311 batting average. Being a lefty, that increases the chances Crawford reaches base via a hit.

Crawford enters this game with a hit in seven straight games. He should be able to make it 8 straight in the battle of JP’s. 

We also like the fact that the Mariners are the road team and will get nine innings of at-bats. It’s up to Crawford to cash this parlay for us!
