Mariners at Red Sox picks and predictions
Prediction
Mariners 6, Red Sox 4
Moneyline
The MARINERS (-102) are worth a look as short ‘dogs in this series opener, as Seattle sails in on a 3-game winning streak.
In addition, the M’s turn to Gilbert, who has been money on the road. He has a sparkling 2.57 ERA away from home, while Pivetta has been a disaster at Fenway Park this season.
Run line/Against the spread
If you’re a little more on the adventurous side, disregard the moneyline, and roll with SEATTLE -1.5 (+152) at plus-money. The M’s not only swept the White Sox over the weekend, but they managed to win by 3 or more runs and cashing against the run line in each of the outings.
On the flip side, Boston +1.5 (-184) has not only posted a dismal 2-7 mark in the past 9 games, it has lost 5 of those outings by 3 or more runs. In the past 9 games, the Red Sox have a terrible minus-22 run differential, too.

Over/Under
BET OVER 8.5 (-110), which is a strong play based on the recent performances for both teams.
The Red Sox have cashed high in 4 straight, and 7 of the past 8 outings. Boston has coughed up 7 or more runs in 7 of the previous 8 contests, too.
For the M’s, the Over hit in the first 3 games of the road trip, and the total has gone high in 15-4-2 in the past 21 away from home.
