Phillies at Mariners picks and predictions

Prediction

Phillies 6, Mariners 5

Moneyline

LEAN PHILLIES (+100). 

Philadelphia is 4-2 in its last 6 meetings with the Mariners in Seattle. The Phillies are also the slightly better team and are a very solid 26-23 on the road this season.

This is a lean because the Mariners are the hotter team as Philly is only 2-8 in its last 10 and has dropped 5 straight while Seattle is 5-2 in its last 7 overall.

Run line/Against the spread

PASS. 

The line is set too favorably to be worth the risk of betting on. Bet on the moneyline and/or total instead.

Over/Under

BET OVER 8 (-120). 

The Over has hit in each of Philadelphia’s last 4 games and is 6-4 in its last 10.

For Seattle, the Over is 6-1 in its last 7 overall.

The Over has also hit in 2 of the last 3 Philly-Seattle matchups overall, also being 4-1-1 in the last 6 matchups in Seattle.
