Mariners 4, Diamondbacks 2

Moneyline

The Diamondbacks have scored 3 runs in 3 games and are 1-10 in games in which they score 3 or fewer runs.

Opponents have scored more than 3 runs only once in Gilbert's 5 starts.  Seattle has won 8 of the 10 games and have allowed 3 or fewer runs in 11 of their last 12 games.

Betting Seattle on the moneyline isn't a bad bet, but there is more money to be made on the run line.

PASS.

Eleven of Seattle's last 12 wins have been by at least 2 runs while the Diamondbacks' last 7 losses and 10 of their last 11 losses have been by multiple runs.

BET MARINER -1.5 (+145).

Over/Under

Each of the first 2 games of the series had totals of 7 or fewer runs.

Seattle's last 5 games and 9 of their last 10 have not reached 8 total runs and 4 of Gilbert's 5 starts have not reached 8 total runs.

BET UNDER 7.5 (-115).
