Mariners at Mets picks and predictions

Prediction

Mariners 4, Mets 3

Moneyline

BET MARINERS (+100).

The Mariners are 8-2 over their last 10 games, while the Mets are 1-9 in that stretch and have gone 2-13 over their last 15. New York holds just a half-game lead over the Cincinnati Reds for the final NL Wild Card spot.

While the Mets have fared better at home, Castillo holds the edge over Manaea in the pitching matchup, with Manaea allowing at least 4 earned runs in each of his last 2 starts.

Run line/Against the spread

PASS.

While 4 of the Mets' last 9 losses have come by at least 2 runs, the best value is on the Mariners' moneyline.

Over/Under

BET UNDER 8.5 (-120).

The Mariners have scored 3 or fewer runs in each of their last 3 games and 4 or fewer runs in 5 of their last 7. They have allowed 4 or fewer runs in 8 of their last 10.

The Mets have scored 4 or fewer runs in 6 of their last 10.

Expect the series opener -- the first meeting between these teams this season -- to stay competitive, with both clubs chasing postseason spots.
