Tips and predictions for Rangers at Mariners

forecast

Mariners 6, Rangers 3

Money line

HAPPEN.

There are no big wins on the moneyline here. The Mariners (-135) are too expensive, and the Rangers, with a starter making his debut, aren’t big underdogs either.

Avoid this option.

Running Line/Against the Spread

Bet Mariners -1.5 (+170).

Seattle has dominated the season series, winning 3 of 6 games by multiple runs. In a 3-game home series against Texas from June 14-16, they went 3-0 and 2-1 on the run line. The Mariners have not had a 1-run win since August 25 and are 5-2 ATS in their last 7 games.

The Rangers also haven’t had a 1-run loss since August 16th and have lost 3 of their last 5 games. Considering these trends and the difference in starting pitchers, MARINERS -1.5 (+170).

Over/Under

Bet over 7 (-120).

The Rangers have scored overs in 3 of their last 4 games and have scored 17 runs in their last 4 games. Texas has allowed 28 in those games. They are 7-3 O/U in their last 10 games.

The Mariners have a record of 4-1-2 O/U in their last 7 games and have scored at least 5 runs in 5 of their last 7 games. Seattle has also scored in double figures in 2 of their last 7 games. OVER 7 (-120).
