Mariners at Yankees picks and predictions

Prediction

Mariners 5, Yankees 4

Moneyline

Seattle is 6-3 across its last 9 getaway games.

Castillo has held current New York batters to an aggregate .541 OPS in past meetings, per ESPN. Gil has been terrific, but he has mostly pitched through the lessened traffic of a .217 batting average on balls in play. There has been some good fortune to his numbers so far.

The New York bullpen figures to have more warts than what shows in its surface line, and they have shown during this series. And strength of schedule is often overlooked in baseball betting, as many bettors assume the everyday slate levels everything in a matter of weeks. That is not always the case, and sometimes it figures into a component lean. For example, the Yankees’ pitching-faced slate to date has been a weak one.

FanDuel Sportsbook has a better price here. Consider a partial-unit play on SEATTLE (+122). Go in heavier at +125 or better.

Run line/Against the spread

FanDuel offers a RL Seattle play (+1.5) at -156. That’s enticing as both clubs have played more 1-run games than average. A slight lean but no more.

Over/Under

The total has gone Over in 5 of Seattle’s last 6 games. The total has gone Over in 8 of the Mariners’ last 9 games on the road and has hit in 6 of Seattle’s last 8 games at Yankee Stadium.

On a humid day with a slight outward breeze in the forecast (and 2 fly-ball pitchers on the mound), BACK THE OVER 8.5 (-105).
